Restructuring and Related Activities [Abstract]
Restructuring Charges	Restructuring and Asset Impairment Charges Restructuring From time to time, the Company will incur costs related to restructuring actions in order to optimize our cost base and more strategically position itself. During the three months ended March 31, 2022, we incurred restructuring charges that were less than $1 million. During the three months ended March 31, 2021, we recognized restructuring charges of $5 million of which $4 million relates to actions previously announced in 2020 arising as a result of the COVID-19 pandemic. These charges included reduction of headcount across all segments and asset impairments within our Measurement & Control Solutions segment. The following table presents the components of restructuring expense and asset impairment charges: Three Months Ended March 31, (in millions) 2022 2021 By component: Severance and other charges $ — $ 4 Asset impairment — 1 Total restructuring charges $ — $ 5 Asset impairment charges — 1 Total restructuring and asset impairment charges $ — $ 6 By segment: Water Infrastructure $ — $ 4 Applied Water — 1 Measurement & Control Solutions — 1 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 three months ended March 31, 2022 and 2021: (in millions) 2022 2021 Restructuring accruals - January 1 $ 7 $ 29 Restructuring charges, net — 5 Cash payments (3) (12) Asset impairment — (1) Restructuring accruals - March 31 $ 4 $ 21 By segment: Water Infrastructure $ — $ 2 Applied Water — 1 Measurement & Control Solutions 3 14 Regional selling locations (a) 1 4 Corporate and other — — (a) Regional selling locations consist primarily of selling and marketing organizations and related support services that incurred restructuring expense that was allocated to the segments.

Background and Basis of Presentation	Mar. 31, 2022
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 17, "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, 2021 ("2021 Annual Report") in preparing these unaudited condensed consolidated financial statements. These condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the notes included in our 2021 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, post-retirement obligations and assets, revenue recognition, income taxes, valuation of intangible assets, goodwill and indefinite-lived intangible impairment testing and contingent liabilities. Actual results could differ from these estimates. The global outbreak of the novel coronavirus ("COVID-19") disease in March 2020, declared a pandemic by the World Health Organization, has created significant global volatility, uncertainty and macroeconomic 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.

Contract assets relate to costs incurred to perform in advance of scheduled billings. Contract liabilities relate to payments received in advance of performance under the contracts. Changes in contract assets and liabilities are due to our performance under the contract. The table below provides contract assets, contract liabilities, and significant changes in contract assets and liabilities: (in millions) Contract Assets (a) Contract Liabilities Balance at January 1, 2022 $ 125 $ 164 Additions, net 34 62 Revenue recognized from opening balance — (50) Billings transferred to accounts receivable (39) Other (2) (1) Balance at March 31, 2022 $ 118 $ 175 Balance at January 1, 2021 $ 117 $ 166 Additions, net 43 67 Revenue recognized from opening balance — (71) Billings transferred to accounts receivable (50) — Other (1) — Balance at March 31, 2021 $ 109 $ 162 (a) Excludes receivable balances, which are disclosed on the Condensed Consolidated Balance Sheets Performance obligations Delivery schedules vary from customer to customer based upon their requirements. Typically, large projects require longer lead production cycles and delays can occur from time to time. As of March 31, 2022, the aggregate amount of the transaction price allocated to performance obligations that are unsatisfied or partially unsatisfied for contracts with performance obligations, amount to $379 million. We expect to recognize the majority of revenue upon the completion of satisfying these performance obligations in the following 60 months. The Company elects to apply the practical expedient to exclude from this disclosure revenue related to performance obligations that are part of a contract whose original expected duration is less than one year.

Income Taxes	Mar. 31, 2022
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 March 31, 2022 was $16 million resulting in an effective tax rate of 16.4%, compared to a $27 million expense resulting in an effective tax rate of 23.3% for the same period in 2021. The effective tax rate for the three-month period ended March 31, 2022 was lower than the U.S. federal statutory rate primarily due to favorable earnings mix and tax settlement benefits, partially offset by the Global Intangible Low Taxed Income ("GILTI") inclusion. 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 on the proposed assessment and is vigorously defending our position through litigation; however, there can be no assurance that any final determination by the authorities will not be materially different than our position. As of March 31, 2022, we have not recorded any unrecognized tax benefits related to this uncertain tax position.

(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 13, "Share-Based Compensation Plans", to the condensed consolidated financial statements for further detail on the performance share units.

Derivative Financial Instruments	Mar. 31, 2022
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 also 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 $457 million and $301 million as of March 31, 2022 and December 31, 2021, respectively. As of March 31, 2022, 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, sell Canadian Dollar and purchase Euro, purchase U.S. Dollar and sell Canadian Dollar, sell Australian Dollar and purchase Euro, and to purchase Polish Zloty and sell Euro. The purchased notional amounts associated with these currency derivatives are $186 million, $140 million, $49 million, $23 million, $22 million, $20 million and $17 million, respectively. As of December 31, 2021 the purchased notional amounts associated with these currency derivatives are $130 million, $88 million, $31 million, $14 million, $14 million, $13 million and $11 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 the second quarter of 2019 and third quarter of 2020 we entered into additional cross-currency swaps. The total notional amount of derivative instruments designated as net investment hedges was $1,135 million and $1,151 million as of March 31, 2022 and December 31, 2021, respectively. 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 $556 million and $563 million as of March 31, 2022 and December 31, 2021, respectively, net of unamortized discount, as a hedge of a net investment in certain foreign subsidiaries. The table below presents the effect of our derivative financial instruments on the Condensed Consolidated Income Statements and Statements of Comprehensive Income: Three Months Ended March 31, (in millions) 2022 2021 Cash Flow Hedges Foreign Exchange Contracts Amount of (loss) recognized in OCI $ (6) $ (11) Amount of loss (gain) reclassified from OCI into revenue 2 (2) Amount of (gain) reclassified from OCI into cost of revenue — (1) Net Investment Hedges Cross-Currency Swaps Amount of gain recognized in OCI $ 1 $ 30 Amount of income recognized in Interest Expense 6 5 Foreign Currency Denominated Debt Amount of gain recognized in OCI $ 8 $ 26 As of March 31, 2022, $7 million of net losses on cash flow hedges are expected to be reclassified into earnings in the next 12 months. As of March 31, 2022, 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 derivative contracts currently included in our hedging program were as follows: (in millions) March 31, December 31, Derivatives designated as hedging instruments Assets Cash Flow Hedges Other current assets $ 1 $ — Net Investment Hedges Other non-current assets $ 5 $ 8 Liabilities Cash Flow Hedges Other current liabilities $ (6) $ (1) Net Investment Hedges Other non-current accrued liabilities $ (22) $ (26) The fair value of our long-term debt, due in 2023, designated as a net investment hedge was $564 million and $577 million as of March 31, 2022 and December 31, 2021, respectively.

(b) The debt issuance costs and unamortized discount are recognized as a reduction in the carrying value of the Senior Notes in the Condensed Consolidated Balance Sheets and are being amortized to interest expense in our Condensed Consolidated Income Statements over the expected remaining terms of the Senior Notes. Senior Notes On June 26, 2020, we issued 1.950% Senior Notes of $500 million aggregate principal amount due January 2028 (the “Senior Notes due 2028”) and 2.250% Senior Notes of $500 million aggregate principal amount due January 2031 (the “Senior Notes due 2031" and, together with the Senior Notes due 2028, the “Green Bond”). The Green Bond includes covenants that restrict our ability, and the ability of our restricted subsidiaries, to incur debt secured by liens on certain property above a threshold, to engage in certain sale and leaseback transactions involving certain property above a threshold, and to consolidate or merge, or convey or transfer all or substantially all of our assets. We may redeem the Green Bond at any time, at our option, subject to certain conditions, at specified redemption prices, plus accrued and unpaid interest to the redemption date. If a change of control triggering event (as defined in the applicable Green Bond indenture) occurs, we will be required to make an offer to purchase the notes at a price equal to 101% of their principal amount plus accrued and unpaid interest to the date of repurchase. Interest on the Green Bond is payable on January 30 and July 30 of each year. As of March 31, 2022, we are in compliance with all covenants for the Green Bond. On March 11, 2016, we issued 2.250% Senior Notes of €500 million aggregate principal amount due March 2023 (the "Senior Notes due 2023"). On October 11, 2016, we issued 3.250% Senior Notes of $500 million aggregate principal amount due October 2026 (the “Senior Notes due 2026”) and 4.375% Senior Notes of $400 million aggregate principal amount due October 2046 (the “Senior Notes due 2046” and, together with the Senior Notes due 2021, the Senior Notes due 2023 and the Senior Notes due 2026, the “Senior Notes”). The Senior Notes include covenants that restrict our ability, and the ability of our restricted subsidiaries, to incur debt secured by liens on certain property above a threshold, to engage in certain sale and leaseback transactions involving certain property above a threshold, and to consolidate or merge, or convey or transfer all or substantially all of our assets. We may redeem the Senior Notes, as applicable, in whole or in part, at any time at a redemption price equal to the principal amount of the Senior Notes to be redeemed, plus a make-whole premium. We may also redeem the Senior Notes in certain other circumstances, as set forth in the applicable Senior Notes indenture. If a change of control triggering event (as defined in the applicable Senior Notes indenture) occurs, we will be required to make an offer to purchase the Senior Notes at a price equal to 101% of their principal amount plus accrued and unpaid interest to the date of repurchase. Interest on the Senior Notes due 2021 is payable on April 1 and October 1 of each year. Interest on the Senior Notes due 2023 is payable on March 11 of each year. Interest on the Senior Notes due 2026 and the Senior Notes due 2046 is payable on May 1 and November 1 of each year. As of March 31, 2022, we are in compliance with all covenants for the Senior Notes. Credit Facilities 2019 Five-Year Revolving Credit Facility On March 5, 2019, Xylem entered into a Five-Year Revolving Credit Facility (the “2019 Credit Facility”) with Citibank, N.A., as Administrative Agent, and a syndicate of lenders. The 2019 Credit Facility provides for an aggregate principal amount of up to $800 million (available in U.S. Dollars and in Euros), with increases of up to $200 million for a maximum aggregate principal amount of $1 billion at the request of Xylem and with the consent of the institutions providing such increased commitments. 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 ("ESG") score, determined based on the methodology in effect as of March 5, 2019. 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 ESG 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 contains 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. As of March 31, 2022, the 2019 Credit Facility was undrawn and we are in compliance with all revolver covenants. Commercial Paper U.S. Dollar Commercial Paper Program Our U.S. Dollar commercial paper program generally serves as a means of short-term funding with a $600 million maximum issuing balance and a combined limit of $800 million inclusive of the 2019 Credit Facility. As of March 31, 2022 and December 31, 2021, none of the Company's $600 million U.S. Dollar commercial paper program was outstanding. We have the ability to continue borrowing under this program going forward in future periods. Euro Commercial Paper Program On June 3, 2019, Xylem entered into a Euro commercial paper program with ING Bank N.V., as administrative agent, and a syndicate of dealers. The Euro commercial paper program provides for a maximum issuing balance of up to €500 million (approximately $557 million) which may be denominated in a variety of currencies. The maximum issuing balance may be increased in accordance with the Dealer Agreement. As of March 31, 2022 and December 31, 2021, none of the Company's Euro commercial paper program was outstanding. We have the ability to continue borrowing under this program going forward in future periods.

The total net periodic benefit cost for other post-retirement 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 months ended March 31, 2022 and 2021, respectively. We contributed $5 million and $6 million to our defined benefit plans during the three months ended March 31, 2022 and 2021, respectively. Additional contributions ranging between approximately $11 million and $19 million are expected to be made during the remainder of 2022. 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 U.K., 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 mid-2022 .

Share-based Payment Arrangement [Abstract]
Share-Based Compensation Plans	Share-Based Compensation Plans Share-based compensation expense was $9 million during both the three months ended March 31, 2022 and 2021. The unrecognized compensation expense related to our stock options, restricted stock units and performance share units was $10 million, $38 million and $20 million, respectively, at March 31, 2022 and is expected to be recognized over a weighted average period of 2.2, 2.3 and 2.6 years, respectively. The amount of cash received from the exercise of stock options was $1 million and $3 million for the three months ended March 31, 2022 and 2021, respectively. Stock Option Grants The following is a summary of the changes in outstanding stock options for the three months ended March 31, 2022 : Share units (in thousands) Weighted Average Exercise Price / Share Weighted Average Remaining Contractual Term (Years) Aggregate Intrinsic Value (in millions) Outstanding at January 1, 2022 1,827 $ 64.12 6.1 102 Granted 306 86.76 Exercised (12) 42.35 Forfeited and expired (7) 88.93 Outstanding at March 31, 2022 2,114 $ 67.44 6.5 $ 44 Options exercisable at March 31, 2022 1,425 $ 58.69 5.2 $ 41 Vested and expected to vest as of March 31, 2022 2,022 $ 66.52 6.3 $ 44 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 three months ended March 31, 2022 was $0.6 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 2022 grants: Volatility 26.20 % Risk-free interest rate 1.59 % Dividend yield 1.38 % Expected term (in years) 5.6 Weighted-average fair value / share $ 19.86 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 U.S. 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 three months ended March 31, 2022 . 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 Outstanding at January 1, 2022 484 $ 88.47 Granted 292 86.76 Vested (179) 85.77 Forfeited (12) 90.74 Outstanding at March 31, 2022 585 $ 88.41 ROIC Performance Share Unit Grants The following is a summary of Return on Invested Capital ("ROIC") performance share unit grants for the three months ended March 31, 2022. 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 Outstanding at January 1, 2022 177 $ 84.84 Granted 35 86.76 Forfeited (a) (55) 74.54 Outstanding at March 31, 2022 157 $ 88.90 (a) Includes ROIC performance share unit awards forfeited during the period as a result of the final performance condition not being achieved on vest date. TSR Performance Share Unit Grants The following is a summary of our Total Shareholder Return ("TSR") performance share unit grants for the three months ended March 31, 2022: Share units (in thousands) Weighted Outstanding at January 1, 2022 177 $ 102.96 Granted 70 71.14 Adjustment for Market Condition Achieved (a) 22 89.62 Vested (75) 89.62 Forfeited (2) 85.01 Outstanding at March 31, 2022 192 $ 100.73 (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. The fair value of TSR performance share units was calculated on the date of grant using a Monte Carlo simulation model utilizing several key assumptions, including expected Company and peer company share price volatility, correlation coefficients between peers, the risk-free rate of return, the expected dividend yield and other award design features. The following are weighted-average assumptions for 2022 grants: Volatility 33.3 % Risk-free interest rate 1.44 % Revenue Performance Share Unit Grants The following is a summary of our Revenue performance share unit grants for the three months ended March 31, 2022: Share units (in thousands) Weighted Outstanding at January 1, 2022 — $ — Granted 35 86.76 Outstanding at March 31, 2022 35 $ 86.76 The fair value of the Revenue performance share unit awards is determined using the closing price of our common stock on date of grant.

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, property damage, personal injury, privacy, employment, labor and pension, government contract issues and commercial or contractual disputes. See Note 4, "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 as of March 31, 2022 and December 31, 2021 for these general legal matters. 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 March 31, 2022 and December 31, 2021, the amount of surety bonds, bank guarantees, insurance letters of credit, stand-by letters of credit as well as revenue and customs guarantees was $431 million and $415 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 U.S. 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, 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 $4 million and $3 million as of March 31, 2022 and December 31, 2021 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 changes in the combined current and non-current product warranty accruals over each period: (in millions) 2022 2021 Warranty accrual – January 1 $ 57 $ 65 Net charges for product warranties in the period 5 8 Settlement of warranty claims (6) (9) Foreign currency and other — (2) Warranty accrual - March 31 $ 56 $ 62

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, 2021 ("2021 Annual Report") in preparing these unaudited condensed consolidated financial statements. These condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the notes included in our 2021 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, post-retirement obligations and assets, revenue recognition, income taxes, valuation of intangible assets, goodwill and indefinite-lived intangible impairment testing and contingent liabilities. Actual results could differ from these estimates. The global outbreak of the novel coronavirus ("COVID-19") disease in March 2020, declared a pandemic by the World Health Organization, has created significant global volatility, uncertainty and macroeconomic 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.

(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 13, "Share-Based Compensation Plans", to the condensed consolidated financial statements for further detail on the performance share units.

[1]	Restricted stock unit awards containing rights to non-forfeitable dividends that participate in undistributed earnings with common stockholders 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 13, "Share-Based Compensation Plans", to the condensed consolidated financial statements for further detail on the performance share units.
