Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements Recently Adopted Pronouncements In June 2016, the FASB issued ASU 2016-13, "Financial Instruments-Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments," amending the accounting for the impairment of financial instruments, including trade receivables. Under previous guidance, credit losses were recognized when the applicable losses had a probable likelihood of occurring and this assessment was based on past events and current conditions. The amended current guidance eliminates the “probable” threshold and requires an entity to use a broader range of

Restructuring and Related Activities [Abstract]
Restructuring Charges	Restructuring and Asset Impairment Charges Restructuring In response to the changes in business and economic conditions arising as a result of the COVID-19 pandemic, on June 2, 2020 management committed to restructuring activities across our businesses and functions globally. The plan is designed to support our long-term financial resilience and simplify our operations, strengthen our competitive positioning and better serve our customers. As a result of this action, during the three and six months ended June 30, 2020, we recognized restructuring charges of $38 million and $40 million, respectively. These charges included reduction of headcount across segments and asset impairments within our Measurement & Control Solutions segment. Immaterial restructuring charges incurred during the first quarter are included in the plan information presented below. During the three and six months ended June 30, 2019, we recognized restructuring charges of $14 million and $22 million, respectively. We incurred these charges primarily as a continuation of our efforts to reposition our European and North American businesses to optimize our cost structure and improve our operational efficiency and effectiveness. The charges included the reduction of headcount and consolidation of facilities within our Measurement & Control Solutions and Water Infrastructure segments, as well as headcount reductions within our Applied Water segment. The following table presents the components of restructuring expense and asset impairment charges: Three Months Ended Six Months Ended June 30, June 30, (in millions) 2020 2019 2020 2019 By component: Severance and other charges $ 21 $ 13 $ 23 $ 20 Lease related charges — — — 1 Asset impairment 17 1 17 1 Total restructuring charges $ 38 $ 14 $ 40 $ 22 Asset impairment 10 — 10 3 Total restructuring and asset impairment charges $ 48 $ 14 $ 50 $ 25 By segment: Water Infrastructure $ 6 $ 7 $ 8 $ 11 Applied Water 2 2 2 2 Measurement & Control Solutions 40 5 40 12 The following table displays a roll-forward of the restructuring accruals, presented on our Condensed Consolidated Balance Sheets within "accrued and other current liabilities" and "other non-current accrued liabilities", for the six months ended June 30, 2020 and 2019: (in millions) 2020 2019 Restructuring accruals - January 1 $ 27 $ 5 Restructuring charges 40 22 Cash payments (12) (12) Asset impairment (17) (1) Foreign currency and other (1) — Restructuring accruals - June 30 $ 37 $ 14 By segment: Water Infrastructure $ 4 $ 4 Applied Water 1 2 Measurement & Control Solutions 27 5 Regional selling locations (a) 4 3 Corporate and other 1 — (a) Regional selling locations consist primarily of selling and marketing organizations and related support services that incurred restructuring expense which was allocated to the segments.

These actions are expected to continue through 2021. The Water Infrastructure, Applied Water, and Measurement & Control Solutions actions commenced in 2019 consist primarily of severance charges. The actions commenced in 2019 are complete. The Water Infrastructure, Applied Water and Measurement & Control Solutions actions commenced in 2017 consist primarily of severance charges and are complete. The discontinuance of a product line resulted in $17 million of asset impairments, primarily related to customer relationships, trademarks and fixed assets within our Measurement & Control Solutions segment. Asset Impairment During the second quarter of 2020 we determined that internally developed in-process software within our Measurement & Control Solutions segment was impaired as a result of actions taken to prioritize strategic investments. Accordingly we recognized an impairment charge of $10 million. Refer to Note 9, "Goodwill and Other Intangible Assets," for additional information. During the first quarter of 2019 we determined that certain assets within our Measurement & Control Solutions segment, including a customer relationship, were impaired. Accordingly we recognized an impairment charge of $3 million. Refer to Note 9, "Goodwill and Other Intangible Assets," for additional information.

Accounting Policies [Abstract]
Background and Basis of Presentation	Background and Basis of Presentation Background Xylem Inc. (“Xylem” or the “Company”) is a leading equipment and service provider for water and wastewater applications with a broad portfolio of products and services addressing the full cycle of water, from collection, distribution and use to the return of water to the environment. Xylem operates in three segments, Water Infrastructure, Applied Water and Measurement & Control Solutions. See Note 19, "Segment Information", to the condensed consolidated financial statements for further segment background information. Except as otherwise indicated or unless the context otherwise requires, "Xylem," "we," "us," "our" and the "Company" refer to Xylem Inc. and its subsidiaries. Basis of Presentation The interim condensed consolidated financial statements reflect our financial position and results of operations in conformity with accounting principles generally accepted in the United States of America ("GAAP"). All intercompany transactions between our businesses have been eliminated. The unaudited interim condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC") and, in the opinion of management, reflect all adjustments (which include normal recurring adjustments) considered necessary for a fair statement of the financial position and results of operations for the periods presented. Certain information and note disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such SEC rules. We believe that the disclosures made are adequate to make the information presented not misleading. We consistently applied the accounting policies described in our Annual Report on Form 10-K for the year ended December 31, 2019 ("2019 Annual Report") in preparing these unaudited condensed consolidated financial statements, with the exception of accounting standard updates described in Note 2. These condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the notes included in our 2019 Annual Report. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements, and the reported amounts of revenue and expenses during the reporting period. Estimates are revised as additional information becomes available. Estimates and assumptions are used for, but not limited to, postretirement obligations and assets, revenue recognition, income tax contingency accruals and valuation allowances, goodwill and indefinite lived intangible impairment testing, contingent liabilities and lease accounting. The global outbreak of the novel coronavirus (COVID-19) disease was declared a pandemic by the World Health Organization and a national emergency by the U.S. Government in March 2020 and has created significant global volatility, uncertainty and economic disruption. The COVID-19 pandemic also has caused increased uncertainty in estimates and assumptions affecting the condensed consolidated financial statements. Actual results could differ from these estimates. Our quarterly financial periods end on the Saturday closest to the last day of the calendar quarter, except for the fourth quarter which ends on December 31. For ease of presentation, the condensed consolidated financial statements included herein are described as ending on the last day of the calendar quarter.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Our quarterly provision for income taxes is measured using an estimated annual effective tax rate, adjusted for discrete items within periods presented. The comparison of our effective tax rate between periods is significantly impacted by the level and mix of earnings and losses by tax jurisdiction and discrete items. The income tax provision for the three months ended June 30, 2020 was $4 million resulting in an effective tax rate of 10.9%, compared to a $17 million expense resulting in an effective tax rate of 10.5% for the same period in 2019. The income tax provision for the six months ended June 30, 2020 was $8 million resulting in an effective tax rate of 10.4%, compared to a $32 million expense resulting in an effective tax rate of 12.8% for the same period in 2019. The effective tax rate for the three and six month periods ended June 30, 2020 differs from the United States federal statutory rate primarily due to the mix of earnings in jurisdictions, partially offset by the Global Intangible Low-Taxed Income ("GILTI") inclusion. Additionally, the effective tax rate for the three and six month periods ended June 30, 2020 differs from the same periods in 2019 due to the relative impact of the benefit from favorable equity compensation deductions on the effective tax rate as well as release of unrecognized tax benefits in 2020, offset by changes in tax law in Switzerland in 2019. Unrecognized Tax Benefits We recognize tax benefits from uncertain tax positions only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities or litigation, based on the technical merits of the position. The tax benefits recognized in the condensed consolidated financial statements from such positions are measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate resolution. The amount of unrecognized tax benefits at June 30, 2020 was $126 million, as compared to $129 million at December 31, 2019, which if ultimately recognized will reduce our effective tax rate. We believe that it is reasonably possible that the unrecognized tax benefits will be reduced by approximately $1 million within the next 12 months as a result of the expiration of certain statutes of limitations. We classify interest expense relating to unrecognized tax benefits as a component of other non-operating expense, net, and tax penalties as a component of income tax expense in our Condensed Consolidated Income Statements. As of June 30, 2020, we had $9 million of interest accrued for unrecognized tax benefits. During 2019, Xylem’s Swedish subsidiary received a tax assessment for the 2013 tax year related to the tax treatment of an intercompany transfer of certain intellectual property that was made in connection with a reorganization of our European businesses. The assessment asserts an aggregate amount of approximately $80 million for tax, penalties and interest. Xylem filed an appeal with the Administrative Court of Stockholm. Management, in consultation with external legal advisors, believes it is more likely than not that Xylem will prevail

(b) Incremental shares from stock options, restricted stock units and performance share units are computed by the treasury stock method. The weighted average shares listed below were not included in the computation of diluted earnings per share because to do so would have been anti-dilutive for the periods presented or were otherwise excluded under the treasury stock method. The treasury stock method calculates dilution assuming the exercise of all in-the-money options and vesting of restricted stock units and performance share units, reduced by the repurchase of shares with the proceeds from the assumed exercises and unrecognized compensation expense for outstanding awards. Performance share units will be included in the treasury stock calculation of diluted earnings per share upon achievement of underlying performance or market conditions at the end of the reporting period. See Note 15, "Share-Based Compensation Plans", to the condensed consolidated financial statements for further detail on the performance share units.

During the second quarter of 2020, we recognized impairment charges of $16 million primarily related to customer relationships and trademarks due to discontinuance of a product line within our Measurement & Control Solutions segment. We also determined that internally developed in-process software within our Measurement & Control Solutions segment was impaired as a result of actions taken to prioritize strategic investments and recognized an impairment charge of $10 million. During the first quarter of 2019, we determined that the intended use of a finite-lived customer relationship within the test application of our Measurement & Control Solutions segment had changed. Accordingly we recorded a $3 million impairment charge. The charge was calculated using the income approach and is reflected in “Restructuring and asset impairment charges” in our Condensed Consolidated Income Statements.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	Derivative Financial Instruments Risk Management Objective of Using Derivatives We are exposed to certain risks arising from both our business operations and economic conditions, and we principally manage our exposures to these risks through management of our core business activities. Certain of our foreign operations expose us to fluctuations of foreign interest rates and exchange rates that may impact revenue, expenses, cash receipts, cash payments, and the value of our stockholders' equity. We enter into derivative financial instruments to protect the value or fix the amount of certain cash flows in terms of the functional currency of the business unit with that exposure and reduce the volatility in stockholders' equity. Cash Flow Hedges of Foreign Exchange Risk We are exposed to fluctuations in various foreign currencies against our functional currencies. We use foreign currency derivatives, including currency forward agreements, to manage our exposure to fluctuations in the various exchange rates. Currency forward agreements involve fixing the foreign currency exchange rate for delivery of a specified amount of foreign currency on a specified date. Certain business units with exposure to foreign currency exchange risks have designated certain currency forward agreements as cash flow hedges of forecasted intercompany inventory purchases and sales. Our principal currency exposures relate to the Euro, Swedish Krona, British Pound, Canadian Dollar, Polish Zloty and Australian Dollar. We had foreign exchange contracts with purchased notional amounts totaling $257 million and $0 million as of June 30, 2020 and December 31, 2019, respectively. As of June 30, 2020, our most significant foreign currency derivatives included contracts to sell U.S. Dollar and purchase Euro, purchase Swedish Krona and sell Euro, sell British Pound and purchase Euro, purchase Polish Zloty and sell Euro, purchase U.S. Dollar and sell Canadian Dollar, and to sell Canadian Dollar and purchase Euro. The purchased notional amounts associated with these currency derivatives are $100 million, $83 million, $25 million, $16 million, $15 million and $13 million, respectively. Hedges of Net Investments in Foreign Operations We are exposed to changes in foreign currencies impacting our net investments held in foreign subsidiaries. Cross Currency Swaps Beginning in 2015, we entered into cross currency swaps to manage our exposure to fluctuations in the Euro-U.S. Dollar exchange rate. During 2019 we entered into additional cross currency swaps. The total notional amount of derivative instruments designated as net investment hedges was $720 million and $714 million as of June 30, 2020 and December 31, 2019, respectively. In July 2020, we entered into additional cross currency swaps with a notional amount $425 million to manage our exposure to fluctuations in the Euro-U.S. Dollar exchange rate. Foreign Currency Denominated Debt On March 11, 2016, we issued 2.250% Senior Notes of €500 million aggregate principal amount due March 2023. We designated the entirety of the outstanding balance, or $559 million and $554 million as of June 30, 2020 and December 31, 2019, respectively, net of unamortized discount, as a hedge of a net investment in certain foreign subsidiaries.

As of June 30, 2020, no gains or losses on the net investment hedges are expected to be reclassified into earnings over their duration. The fair values of our derivative assets and liabilities are measured on a recurring basis using Level 2 inputs and are determined through the use of models that consider various assumptions including yield curves, time value and other measurements. The fair values of our foreign exchange contracts currently included in our hedging program designated as hedging instruments were as follows: (in millions) June 30, December 31, Derivatives designated as hedging instruments Assets Cash Flow Hedges Other current assets $ 4 $ — Net Investment Hedges Other non-current assets $ 19 $ 4 Liabilities Net Investment Hedges Other non-current accrued liabilities $ (13) $ (24) The fair value of our long-term debt, due in 2023, designated as a net investment hedge was $582 million and $591 million as of June 30, 2020 and December 31, 2019, respectively.

Credit Facilities 2019 Five On March 5, 2019, Xylem entered into a Five Interest on all loans under the 2019 Credit Facility is payable either quarterly or at the expiration of any LIBOR or EURIBOR interest period applicable thereto. Borrowings accrue interest at a rate equal to, at Xylem's election, a base rate or an adjusted LIBOR or EURIBOR rate plus an applicable margin. The 2019 Credit Facility includes customary provisions for implementation of replacement rates for LIBOR-based and EURIBOR-based loans. The 2019 Credit Facility also includes a pricing grid that determines the applicable margin based on Xylem's credit rating, with a further adjustment depending on Xylem's annual Sustainalytics Environmental, Social and Governance score. Xylem will also pay quarterly fees to each lender for such lender’s commitment to lend accruing on such commitment at a rate based on our credit rating, whether such commitment is used or unused, as well as a quarterly letter of credit fee accruing on the letter of credit exposure of such lender during the preceding quarter at a rate based on the credit rating of Xylem (as adjusted for the Environmental, Social and Governance score). The 2019 Credit Facility requires that Xylem maintain a consolidated total debt to consolidated EBITDA ratio (or maximum leverage ratio), which will be based on the last four fiscal quarters, and in addition a number of customary covenants, including limitations on the incurrence of secured debt and debt of subsidiaries, liens, sale and lease-back transactions, mergers, consolidations, liquidations, dissolutions and sales of assets. The 2019 Credit Facility also contains customary events of default. Finally, Xylem has the ability to designate subsidiaries that can borrow under the 2019 Credit Facility, subject to certain requirements and conditions set forth in the 2019 Credit Facility.

This modification is effective through the quarter ending September 30, 2021, after which the covenant will revert back to the prior test maximum leverage ratio. The amendment also restricts stock repurchases until March 31, 2021, except for shares of common stock in an amount not to exceed the number of shares issued after the date of the Amendment, subject to customary exceptions. As of June 30, 2020, the 2019 Credit Facility was undrawn and we are in compliance with all revolver covenants.

The total net periodic benefit cost for other postretirement employee benefit plans was less than $1 million including net credits recognized into other comprehensive income of less than $1 million for both the three and six months ended June 30, 2020. The total net periodic benefit cost for other postretirement employee benefit plans was less than $1 million for both the three and six months ended June 30, 2019, including net credits recognized into other comprehensive income of $1 million for both the three and six months ended June 30, 2019. We contributed $16 million and $9 million to our defined benefit plans during the six months ended June 30, 2020 and 2019, respectively. Additional contributions ranging between approximately $5 million and $15 million are expected during the remainder of 2020. During the first quarter of 2020, the Company purchased a bulk annuity policy with an insurance company for its largest defined benefit plan in the UK, as a plan asset, to facilitate the termination and buy-out of the plan. The bulk annuity fully insures the benefits payable to the participants of the plan until a full buy-out of the plan can be executed, which is expected to occur in 2021. Included in the Company's six months ended June 30, 2020 contributions is $5 million paid to meet the shortfall between the cost of the bulk annuity policy and the plan assets. As a result of the change in assets from a mix of equities and bonds to the bulk annuity, the plan's expected rate of return on assets was reduced to 1.00% at December 31, 2019. The rate at December 31, 2018 was 7.25%. On January 27, 2020, the plan's assets of $336 million were transferred to the insurance company for the purchase of the bulk annuity.

The unrecognized compensation expense related to our stock options, restricted stock units and performance share units was $9 million, $29 million and $14 million, respectively, at June 30, 2020 and is expected to be recognized over a weighted average period of 2.2, 2.1 and 2.2 years, respectively. The amount of cash received from the exercise of stock options was $5 million and $8 million for the six months ended June 30, 2020 and 2019, respectively. Stock Option Grants The following is a summary of the changes in outstanding stock options for the six months ended June 30, 2020 : Share units (in thousands) Weighted Average Exercise Price / Share Weighted Average Remaining Contractual Term (Years) Aggregate Intrinsic Value (in millions) Outstanding at January 1, 2020 2,040 $ 48.56 6.3 Granted 548 74.00 Exercised (131) 41.03 Forfeited and expired (40) 77.28 Outstanding at June 30, 2020 2,417 $ 54.27 6.7 $ 34 Options exercisable at June 30, 2020 1,615 $ 44.49 5.4 $ 33 Vested and expected to vest as of June 30, 2020 2,309 $ 53.36 6.6 $ 33 The total intrinsic value of options exercised (which is the amount by which the stock price exceeded the exercise price of the options on the date of exercise) during the six months ended June 30, 2020 was $5.6 million. Stock Option Fair Value The fair value of each option grant was estimated on the date of grant using the binomial lattice pricing model which incorporates multiple and variable assumptions over time, including assumptions such as employee exercise patterns, stock price volatility and changes in dividends. The following are weighted-average assumptions for 2020 grants: Volatility 24.07 % Risk-free interest rate 15.12 % Dividend yield 1.43 % Expected term (in years) 5.8 Weighted-average fair value / share $ 14.69 Expected volatility is calculated based on an analysis of historic volatility measures for Xylem. We use historical data to estimate option exercise and employee termination behavior within the valuation model. Employee groups and option characteristics are considered separately for valuation purposes. The expected term represents an estimate of the period of time options are expected to remain outstanding. The risk-free rate is based on the United States Treasury yield curve in effect at the time of option grant. Restricted Stock Unit Grants The following is a summary of restricted stock unit activity for the six months ended June 30, 2020 . The fair value of the restricted share unit awards is determined using the closing price of our common stock on date of grant: Share units (in thousands) Weighted Average Grant Date Fair Value /Share Outstanding at January 1, 2020 512 $ 68.95 Granted 317 75.01 Vested (237) 63.32 Forfeited (21) 74.16 Outstanding at June 30, 2020 571 $ 74.42 ROIC Performance Share Unit Grants The following is a summary of Return on Invested Capital ("ROIC") performance share unit grants for the six months ended June 30, 2020. The fair value of the ROIC performance share units is equal to the closing share price on the date of the grant: Share units (in thousands) Weighted Average Grant Date Fair Value /Share Outstanding at January 1, 2020 225 $ 64.51 Granted 78 78.30 Vested (89) 49.15 Forfeited (8) 77.05 Outstanding at June 30, 2020 206 $ 75.89 TSR Performance Share Unit Grants The following is a summary of our Total Shareholder Return ("TSR") performance share unit grants for the six months ended June 30, 2020: Share units (in thousands) Weighted Average Grant Date Fair Value /Share Outstanding at January 1, 2020 225 $ 75.80 Granted 78 100.69 Adjustment for Market Condition Achieved (a) 35 49.15 Vested (124) 49.15 Forfeited (8) 77.05 Outstanding at June 30, 2020 206 $ 96.47 (a) Represents an increase in the number of original TSR performance share units awarded based on the final market condition achievement at the end of the performance period of such awards.

Commitments and Contingencies

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Legal Proceedings From time to time we are involved in legal and regulatory proceedings that are incidental to the operation of our businesses (or the business operations of previously-owned entities). These proceedings may seek remedies relating to matters including environmental, tax, intellectual property, acquisitions or divestitures, product liability and personal injury, privacy, employment, labor and pension, government contract issues and commercial or contractual disputes. From time to time, claims may be asserted against Xylem alleging injury caused by any of our products resulting from asbestos exposure. We believe there are numerous legal defenses available for such claims and would defend ourselves vigorously. Pursuant to the Distribution Agreement among ITT Corporation (now ITT LLC), Exelis and Xylem, ITT Corporation (now ITT LLC) has an obligation to indemnify, defend and hold Xylem harmless for asbestos product liability matters, including settlements, judgments, and legal defense costs associated with all pending and future claims that may arise from past sales of ITT’s legacy products. We believe ITT Corporation (now ITT LLC) remains a substantial entity with sufficient financial resources to honor its obligations to us. See Note 6, "Income Taxes", of our condensed consolidated financial statements for a description of a pending tax litigation matter. Although the ultimate outcome of any legal matter cannot be predicted with certainty, based on present information, including our assessment of the merits of the particular claims, we do not believe it is reasonably possible that any asserted or unasserted legal claims or proceedings, individually or in aggregate, will have a material adverse effect on our results of operations, or financial condition. We have estimated and accrued $4 million and $5 million as of June 30, 2020 and December 31, 2019, respectively, for these general legal matters. Indemnifications As part of our 2011 spin-off from our former parent, ITT Corporation (now ITT LLC), Exelis Inc. and Xylem will indemnify, defend and hold harmless each of the other parties with respect to such parties’ assumed or retained liabilities under the Distribution Agreement and breaches of the Distribution Agreement or related spin agreements. The former parent’s indemnification obligations include asserted and unasserted asbestos and silica liability claims that relate to the presence or alleged presence of asbestos or silica in products manufactured, repaired or sold prior to October 31, 2011, the Distribution Date, subject to limited exceptions with respect to certain employee claims, or in the structure or material of any building or facility, subject to exceptions with respect to employee claims relating to Xylem buildings or facilities. The indemnification associated with pending and future asbestos claims does not expire. Xylem has not recorded a liability for material matters for which we expect to be indemnified by the former parent or Exelis Inc. through the Distribution Agreement and we are not aware of any claims or other circumstances that would give rise to material payments from us under such indemnifications. On May 29, 2015, Harris Inc. acquired Exelis. As the parent of Exelis, Harris Inc. is responsible for Exelis’ indemnification obligations under the Distribution Agreement. Guarantees We obtain certain stand-by letters of credit, bank guarantees, surety bonds and insurance letters of credit from third-party financial institutions in the ordinary course of business when required under contracts or to satisfy insurance related requirements. As of June 30, 2020 and December 31, 2019, the amount of surety bonds, bank guarantees, insurance letters of credit and stand-by letters of credit was $298 million and $340 million, respectively. Environmental In the ordinary course of business, we are subject to federal, state, local, and foreign environmental laws and regulations. We are responsible, or are alleged to be responsible, for ongoing environmental investigation and remediation of sites in various countries. These sites are in various stages of investigation and/or remediation and in many of these proceedings our liability is considered de minimis. We have received notification from the United States Environmental Protection Agency, and from similar state and foreign environmental agencies, that a number of sites formerly or currently owned and/or operated by Xylem or for which we are responsible under the Distribution Agreement, and other properties or water supplies that may be or have been impacted from those operations, contain disposed or recycled materials or wastes and require environmental investigation and/or remediation. These sites include instances where we have been identified as a potentially responsible party under federal and state environmental laws and regulations. Accruals for environmental matters are recorded on a site-by-site basis when it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated, based on current law and existing technologies. Our accrued liabilities for these environmental matters represent our best estimates related to the investigation and remediation of environmental media such as water, soil, soil vapor, air and structures, as well as related legal fees. These estimates, and related accruals, are reviewed quarterly and updated for progress of investigation and remediation efforts and changes in facts and legal circumstances. Liabilities for these environmental expenditures are recorded on an undiscounted basis. We have estimated and accrued $3 million as of June 30, 2020 and December 31, 2019 for environmental matters. It is difficult to estimate the final costs of investigation and remediation due to various factors, including incomplete information regarding particular sites and other potentially responsible parties, uncertainty regarding the extent of investigation or remediation and our share, if any, of liability for such conditions, the selection of alternative remedial approaches, and changes in environmental standards and regulatory requirements. We believe the total amount accrued is reasonable based on existing facts and circumstances. Warranties We warrant numerous products, the terms of which vary widely. In general, we warrant products against defect and specific non-performance. The table below provides the changes in our product warranty accrual: (in millions) 2020 2019 Warranty accrual – January 1 $ 41 $ 60 Net charges for product warranties in the period 34 11 Settlement of warranty claims (15) (23) Warranty accrual - June 30 $ 60 $ 48

Segment Reporting [Abstract]
Segment Information	Segment Information Our business has three reportable segments: Water Infrastructure, Applied Water and Measurement & Control Solutions. When determining the reportable segments, the Company aggregated operating segments based on their similar economic and operating characteristics. The Water Infrastructure segment focuses on the transportation and treatment of water, offering a range of products including water, wastewater and storm water pumps, treatment equipment, and controls and systems. The Applied Water segment serves many of the primary uses of water and focuses on the residential, commercial and industrial markets. The Applied Water segment's major products include pumps, valves, heat exchangers, controls and dispensing equipment. The Measurement & Control Solutions segment focuses on developing advanced technology solutions that enable intelligent use and conservation of critical water and energy resources as well as analytical instrumentation used in the testing of water. The Measurement & Control Solutions segment's major products include smart metering, networked communications, measurement and control technologies, critical infrastructure technologies, software and services including cloud-based analytics, remote monitoring and data management, leak detection and pressure monitoring solutions and testing equipment. Additionally, we have Regional selling locations, which consist primarily of selling and marketing organizations and related support services, that offer products and services across our reportable segments. Corporate and other consists of corporate office expenses including compensation, benefits, occupancy, depreciation, and other administrative costs, as well as charges related to certain matters, such as environmental matters, that are managed at a corporate level and are not included in the business segments in evaluating performance or allocating resources. The accounting policies of each segment are the same as those described in the summary of significant accounting policies (see Note 1 in the 2019 Annual Report). The following tables contain financial information for each reportable segment: Three Months Ended Six Months Ended June 30, June 30, (in millions) 2020 2019 2020 2019 Revenue: Water Infrastructure $ 501 $ 561 $ 939 $ 1,043 Applied Water 337 394 675 773 Measurement & Control Solutions 322 390 669 766 Total $ 1,160 $ 1,345 $ 2,283 $ 2,582 Operating Income: Water Infrastructure $ 73 $ 98 $ 112 $ 149 Applied Water 41 62 88 118 Measurement & Control Solutions (46) 26 (58) 42 Corporate and other (14) (15) (27) (29) Total operating income $ 54 $ 171 $ 115 $ 280 Interest expense $ 18 $ 18 $ 34 $ 36 Other non-operating (expense) income, net (1) 3 (4) 5 Gain from sale of business — — — 1 Income before taxes $ 35 $ 156 $ 77 $ 250 Depreciation and Amortization: Water Infrastructure $ 16 $ 16 $ 31 $ 31 Applied Water 5 6 11 12 Measurement & Control Solutions 34 35 70 71 Regional selling locations (a) 7 4 11 8 Corporate and other — 2 3 5 Total $ 62 $ 63 $ 126 $ 127 Capital Expenditures: Water Infrastructure $ 8 $ 21 $ 18 $ 51 Applied Water 3 4 12 10 Measurement & Control Solutions 24 29 51 53 Regional selling locations (b) 8 5 12 9 Corporate and other 1 1 2 6 Total $ 44 $ 60 $ 95 $ 129 (a) Depreciation and amortization expense incurred by the Regional selling locations was included in an overall allocation of Regional selling location costs to the segments; however, a certain portion of that expense was not specifically identified to a segment.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The interim condensed consolidated financial statements reflect our financial position and results of operations in conformity with accounting principles generally accepted in the United States of America ("GAAP"). All intercompany transactions between our businesses have been eliminated. The unaudited interim condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC") and, in the opinion of management, reflect all adjustments (which include normal recurring adjustments) considered necessary for a fair statement of the financial position and results of operations for the periods presented. Certain information and note disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such SEC rules. We believe that the disclosures made are adequate to make the information presented not misleading. We consistently applied the accounting policies described in our Annual Report on Form 10-K for the year ended December 31, 2019 ("2019 Annual Report") in preparing these unaudited condensed consolidated financial statements, with the exception of accounting standard updates described in Note 2. These condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the notes included in our 2019 Annual Report. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements, and the reported amounts of revenue and expenses during the reporting period. Estimates are revised as additional information becomes available. Estimates and assumptions are used for, but not limited to, postretirement obligations and assets, revenue recognition, income tax contingency accruals and valuation allowances, goodwill and indefinite lived intangible impairment testing, contingent liabilities and lease accounting. The global outbreak of the novel coronavirus (COVID-19) disease was declared a pandemic by the World Health Organization and a national emergency by the U.S. Government in March 2020 and has created significant global volatility, uncertainty and economic disruption. The COVID-19 pandemic also has caused increased uncertainty in estimates and assumptions affecting the condensed consolidated financial statements. Actual results could differ from these estimates. Our quarterly financial periods end on the Saturday closest to the last day of the calendar quarter, except for the fourth quarter which ends on December 31. For ease of presentation, the condensed consolidated financial statements included herein are described as ending on the last day of the calendar quarter.
Pronouncements Not Yet Adopted and Recently Adopted Pronouncements	Recently Adopted Pronouncements In June 2016, the FASB issued ASU 2016-13, "Financial Instruments-Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments," amending the accounting for the impairment of financial instruments, including trade receivables. Under previous guidance, credit losses were recognized when the applicable losses had a probable likelihood of occurring and this assessment was based on past events and current conditions. The amended current guidance eliminates the “probable” threshold and requires an entity to use a broader range of

(b) Incremental shares from stock options, restricted stock units and performance share units are computed by the treasury stock method. The weighted average shares listed below were not included in the computation of diluted earnings per share because to do so would have been anti-dilutive for the periods presented or were otherwise excluded under the treasury stock method. The treasury stock method calculates dilution assuming the exercise of all in-the-money options and vesting of restricted stock units and performance share units, reduced by the repurchase of shares with the proceeds from the assumed exercises and unrecognized compensation expense for outstanding awards. Performance share units will be included in the treasury stock calculation of diluted earnings per share upon achievement of underlying performance or market conditions at the end of the reporting period.

[1]	Restricted stock unit awards containing rights to non-forfeitable dividends that participate in undistributed earnings with common shareholders are considered participating securities for purposes of computing earnings per share.
[2]	Incremental shares from stock options, restricted stock units and performance share units are computed by the treasury stock method. The weighted average shares listed below were not included in the computation of diluted earnings per share because to do so would have been anti-dilutive for the periods presented or were otherwise excluded under the treasury stock method. The treasury stock method calculates dilution assuming the exercise of all in-the-money options and vesting of restricted stock units and performance share units, reduced by the repurchase of shares with the proceeds from the assumed exercises and unrecognized compensation expense for outstanding awards. Performance share units will be included in the treasury stock calculation of diluted earnings per share upon achievement of underlying performance or market conditions at the end of the reporting period. See Note 15, "Share-Based Compensation Plans", to the condensed consolidated financial statements for further detail on the performance share units.
