EXHIBIT 10.12

                  INSITUFORM TECHNOLOGIES, INC.

                 1992 DIRECTOR STOCK OPTION PLAN

                 (as amended February 17, 2000)

          1.   Purposes of Plan.  The purposes of this Plan, which
shall be known as the Insituform Technologies, Inc. 1992 Director
Stock Option Plan, and is hereinafter referred to as the "Plan",
are (i) to provide incentives for members of the Board of Directors
of Insituform Technologies, Inc. (the "Company") by encouraging
their ownership of the class A common stock, $.01 par value (the
"Common Stock"), of the Company, and (ii) to aid the Company in
retaining such directors, upon whose efforts the Company's success
and future growth depends, and attracting other such directors.

          2.   Administration.  The Plan shall be administered by
the Board of Directors of the Company or, as determined by the
Board of Directors in its sole discretion, by a committee from time
to time appointed by the Board of Directors and consisting of not
less than two of its members (the Board of Directors, or such
committee, for purposes of this Plan hereinafter referred to as the
"Committee"), as hereinafter provided. Subject to the terms of the
Plan, the Committee shall have plenary authority to determine the
directors to whom options are to be granted, the number of shares
to be subject to each such option, the terms and conditions upon
which the options are granted and are exercisable, and whether such
options will be incentive stock options or non-qualified stock
options. For purposes of administration, the Committee, subject to
the terms of the Plan, shall have plenary authority to establish
such rules and regulations, make such determinations and
interpretations, and take such other administrative actions as it
deems necessary or advisable.  All determinations and
interpretations made by the Committee shall be final, conclusive
and binding on all persons, including Optionees (as hereinafter
defined) and their legal representatives and beneficiaries.

          The Board of Directors shall designate one of the members
of the Committee as its Chairman.  The Committee shall hold its
meetings at such times and at such places as it may determine.  A
majority of its members shall constitute a quorum.  All
determinations of the Committee shall be made by a majority of its
members.  Any decision or determination reduced to writing and
signed by all members shall be as effective as if it had been made
by a majority vote at a meeting duly called and held.  The
Committee may appoint a secretary (who need not be a member of the
Committee).  No member of the Committee shall be liable for any act
or omission with respect to his service on the Committee if he acts
in good faith and in a manner he reasonably believes to be in or
not opposed to the best interests of the Company.  Service on the
Committee shall constitute service as a director of the Company for
all purposes.


          3.   Stock Available for Options.  There shall be
available for options under the Plan a total of 1,500,000 shares
of Common Stock, subject to any adjustments which may be made
pursuant to Section 5(f) hereof.*  Shares of Common Stock used for
purposes of the Plan may be either authorized and unissued shares,
or previously issued shares held in the treasury of the Company, or
both.  Shares of Common Stock covered by options which have
terminated or expired prior to exercise shall be available for
further options hereunder.

          4.   Eligibility.  Options under the Plan may be granted
to directors of the Company (including officers, key employees and
consultants of the Company).  Options may be granted to such
directors whether or not they hold or have held options previously
granted under the Plan or otherwise granted or assumed by the
Company.  In selecting directors for options, the Committee may
take into consideration any factors it may deem relevant, including
its estimate of the director's present and potential contributions
to the success of the Company.

          5.   Terms and Conditions of Options.  The Committee
shall, in its discretion, prescribe the terms and conditions of
the options to be granted hereunder which terms and conditions
need not be the same in each case, subject to the following:

               (a)    Option Price.  The price at which each share
of Common Stock covered by an option granted under the Plan may be
purchased shall be determined by the Committee and shall not be
less than the lesser of (i) the tangible book value per share of
Common Stock, determined in accordance with generally accepted
accounting principles, as of the end of the fiscal quarter of the
Company immediately preceding the fiscal quarter in which the
option is granted, or (ii) the market value per share of Common
Stock on the date of grant of an option as determined pursuant to
Section 5(c).  The date of the grant of an option shall be the date
specified by the Committee in its grant of the option.

               (b)    Option Period.  The period for exercise of an
option shall in no event be more than ten years from the date of
grant. Options may, in the discretion of the Committee, be made
exercisable in installments during the option period.  Any shares
not purchased on any applicable installment date may be purchased
thereafter at any time before the expiration of the option period.

               (c)    Exercise of Options.  In order to exercise an
option, the holder thereof (the "Optionee") shall deliver to the

- -----------------------------
*    subject to shareholder approval




Company written notice specifying the number of shares of Common
Stock to be purchased, together with cash or a certified or bank
cashier's check payable to the order of the Company in the full
amount of the purchase price therefor; provided that, for the
purpose of assisting an Optionee to exercise an option, the Company
may make loans to the Optionee or guarantee loans made by third
parties to the Optionee, on such terms and conditions as the Board
of Directors may authorize; and provided further that such purchase
price may be paid in shares of Common Stock owned by the Optionee
having a market value on the date of exercise equal to the
aggregate purchase price, or in a combination of cash and Common
Stock.  For purposes of the Plan, the market value per share of
Common Stock shall be the last sale price regular way on the date
of reference, or, in case no sale takes place on such day, the
average of the closing bid and asked prices regular way, in either
case on the principal national securities exchange on which the
Common Stock is listed or admitted to trading, or if the Common
Stock is not listed or admitted to trading on any national
securities exchange, the last sale price of the Common Stock as
reported on the National Association of Securities Dealers
Automated Quotation ("NASDAQ") National Market System on such date,
or if the Common Stock is not so reported, the average of the
closing high bid and low asked prices of the Common Stock in the
over-the-counter market on such date, as reported on the NASDAQ
system, or if there are no such prices reported on the NASDAQ
system on such date, as furnished to the Committee by a New York
Stock Exchange member selected from time to time by the Committee
for such purpose.  If there is no bid or asked price reported on
any such date, the market value shall be determined by the
Committee in accordance with the regulations promulgated under
Section 2031 of the Code, or by any other appropriate method
selected by the Committee. An Optionee shall have none of the
rights of a stockholder until the shares of Common Stock are issued
to him.  An option may not be exercised for less than 1,000 shares
of Common Stock, or the number of shares of Common Stock remaining
subject to such option, whichever is smaller.

               (d)    Effect of Termination of Service.  An option
may not be exercised after the Optionee has ceased to be in the
service of the Company or any parent or subsidiary corporations
(within the respective meanings of Sections 424(e) and 424(f) of
the Internal Revenue Code of 1986, as amended [the "Code"], and
referred to herein as "Parent" or "Subsidiary", respectively),
whether as a director of the Company or an employee or consultant
of the Company or any Parent or Subsidiary thereof, except in the
following circumstances:

               (i)   if (x) the Optionee's service as a
          director is terminated for any reason, and (y)
          the Optionee is not an employee or consultant
          of the Company or any Parent or Subsidiary
          thereof, or his employ is terminated at or
          after age 60 or by action of the Company, the


          option may be exercised by the Optionee within
          30 days after the last such termination, but
          only as to any shares exercisable on the date
          the Optionee's service and/or employment so
          terminates;

               (ii)   if the Optionee's service and/or
          employment is terminated by reason of the
          Optionee's total and permanent disability
          (pursuant to the terms of any employee
          disability benefit plan maintained by the
          Company or any Parent or Subsidiary thereof)
          while employed by the Company or any Parent or
          Subsidiary thereof, the option shall thereupon
          become exercisable in full by the Optionee
          within 30 days after such termination;

               (iii)  in the event of the death of the
          Optionee during the 30-day period after
          termination of service and/or employment
          covered by (i) above, the Optionee's
          beneficiary or the person or persons to whom
          his rights are transferred by will or the laws
          of descent and distribution shall have a
          period of one year from the date of his death
          to exercise any options which were exercisable
          by the Optionee at the time of his death;

               (iv) in the event of the death of the
          Optionee while serving as a director or
          employed, the option shall thereupon become
          exercisable in full, and the person or persons
          to whom the Optionee's rights are transferred
          by will or the laws of descent and
          distribution shall have a period of one year
          from the date of the Optionee's death to
          exercise such option.


The provisions of the foregoing clauses (ii) and (iii) shall apply
to any outstanding options which are incentive stock options to the
extent permitted by Section 422(d) of the Code and such outstanding
options in excess thereof shall, immediately upon the occurrence of
the event described in the foregoing clauses (ii) and (iii), be
treated for all purposes of the Plan as nonstatutory stock options
and shall be immediately exercisable as such as provided in the
foregoing clauses (ii) and (iii).

          For purposes of this Section 5(d), service as a
consultant of or to the Company or any Parent or Subsidiary shall
be considered employment, and the period of such service shall be
considered the period of employment; provided, however, that
incentive stock options may be granted under the Plan only to a


director who is an "employee" (as such term is used in Section 422
of the Code) of the Company or any Subsidiary or Parent.

          In no event shall any option be exercisable more than ten
years from the date of grant thereof.  Nothing in the Plan or in
any option granted pursuant to the Plan (in the absence of an
express provision to the contrary) shall confer on any individual
any right to continue in the service of the Company or any Parent
or Subsidiary thereof or interfere in any way with the right of the
Company to terminate his service.

               (e)    Nontransferability of Options.  During the
lifetime of an Optionee, options held by such Optionee shall be
exercisable only by him.  No option shall be transferable other
than by will or by the laws of descent and distribution; provided,
however, that Options may, in the discretion of the Committee,
permit the Optionee to designate a beneficiary or beneficiaries, in
the event of the Optionee's death, to exercise the rights of the
Optionee and receive the Stock issued pursuant to the Option. Such
beneficiary designation shall be in such form as shall be
prescribed by the Committee, shall be effective upon delivery to
the Company, and when effective shall revoke all prior
designations.  If an Optionee dies with no such beneficiary
designation in effect, the Option shall be transferred by will or
pursuant to the laws of descent and distribution.

               (f)    Adjustments for Change in Stock Subject to
Plan and Other Events.  In the event of a reorganization,
recapitalization, stock split, stock dividend, combination of
shares, merger, consolidation, rights offering, or any other change
in the corporate structure or shares of the Company, the Committee
shall make such adjustments, if any, as it deems appropriate in the
number and kind of shares subject to the Plan, in the number and
kind of shares covered by outstanding options, or in the option
price per share.

               (g)    Registration, Listing and Qualification
Shares of Stock.  Each option shall be subject to the requirement
that if at any time the Board of Directors shall determine that the
registration, listing or qualification of the shares of Common
Stock covered thereby upon any securities exchange or under any
federal or state law, or the consent or approval of any
governmental regulatory body is necessary or desirable as a
condition of, or in connection with, the granting of such option or
the purchase of shares of Common Stock thereunder, no such option
may be exercised unless and until such registration, listing,
qualification, consent or approval shall have been effected or
obtained free of any conditions not acceptable to the Board of
Directors.  The Company may require that any person exercising an
option shall make such representations and agreements and furnish
such information as it deems appropriate to assure compliance with
the foregoing or any other applicable legal requirement.



               (h)    Other Terms and Conditions.  The Committee
may impose such other terms and conditions, not inconsistent with
the terms hereof, on the grant or exercise of options, as it deems
advisable.

          6.   Provisions Applicable to Incentive Stock Options.
The Committee may, in its discretion, grant "incentive stock
options" (within the meaning of Section 422 of the Code), under the
Plan to directors provided, however, that: (a) no such incentive
stock option shall be issued to a director of the Company who is
not also an employee or officer of the Company; (b) no such
incentive stock option shall be granted at an option price which is
less than the market value per share of Common Stock on the date of
the grant; (c) no such incentive stock option shall be issued to
any one Optionee if the aggregate fair market value, determined at
the time of the grant of such incentive stock options, of the
shares with respect to which such incentive stock options are
exercisable for the first time by such Optionee during any calendar
year, together with all options under any other incentive stock
option plan of the Company exercisable during such year, exceeds
$100,000; (d) no such incentive stock option shall be granted to
any Optionee who at the time such option is granted owns more than
10 percent of the total combined  voting stock of the Company
unless (i) the option price is not less than 110 percent of the
fair market value per share of stock on the date of the grant, and
(ii) the option is not exercisable after five years from the date
such option is granted; and (e) Section 5(d)(ii) hereof shall not
apply to any incentive stock option.

          7.   Withholding Tax.  Upon the disposition by any person
of shares of Common Stock acquired pursuant to the exercise of an
option granted pursuant to the Plan, the Company shall have the
right to require such person to pay the Company the amount of any
taxes which the Company may be required to withhold with respect to
such shares.

          8.   Amendment and Termination.  Unless the Plan shall
theretofore have been terminated as hereinafter provided, the Plan
shall terminate on, and no option shall be granted thereunder after
March 31, 2002; provided, however, that the Board of Directors may
at any time prior to that date terminate the Plan. The Board of
Directors may at any time amend the Plan; provided, however, that,
except as contemplated in Section 5(f) hereof, the Board of
Directors shall not, without approval by a majority of the votes
cast by the stockholders of the Company at a meeting of stock-
holders at which a proposal to amend the Plan is voted upon: (i)
increase the maximum number of shares of Stock for which options
may be granted under the Plan, (ii) change the formula as to
minimum option prices, (iii) extend the period during which options
may be granted or exercised, or (iv) amend the requirements as to
the class of persons eligible to receive options. No termination or


amendment of the Plan may, without the consent of an Optionee,
adversely affect the rights of such Optionee under any option held
by such Optionee.

          9.   Effectiveness of Plan.  The Plan will not be made
effective unless approved by a majority of the votes cast by the
stockholders of the Company at a meeting of stockholders within
twelve (12) months from the date the Plan is adopted by the Board
of Directors, duly called and held for such purpose, and no option
granted hereunder shall be exercisable prior to such approval.

          10.  Other Actions.  Nothing contained in the Plan shall
be construed to limit the authority of the Company to exercise its
corporate rights and powers, including but not by way of
limitation, the right of the Company to grant or assume options for
proper corporate purposes other than under the Plan with respect to
any employee or other person, firm, corporation or association.
