Item 4. Description of Securities
        -------------------------

      Not applicable.


Item 5. Interests of Named Experts and Counsel
        --------------------------------------

      The validity of the securities being offered hereby is being
passed upon for the Company by Krugman, Chapnick & Grimshaw, Park
80 West - Plaza Two, Saddle Brook, New Jersey 07663-5819. James D.
Krugman, a partner in Krugman, Chapnick & Grimshaw, is a director
and Chairman of the Board of the Company, and Howard Kailes, a
partner of such firm, is Secretary of the Company. Mr. Krugman owns
10,000 shares of Common Stock; is managing partner of a partnership
which owns 40,364 shares of Common Stock (in 5,046 shares of which
Mr. Krugman has a beneficial interest); has shared voting and
investment power over 33,300 shares of Common Stock owned by a
general partnership in which his mother has an interest; and has
the right to acquire 95,000 additional shares which are issuable
upon the exercise of options granted by the Company (of which
options covering 47,500 shares are currently exercisable).

Item 6. Indemnification of Directors and Officers
        -----------------------------------------

      Under the provisions of Paragraph Seventh of the Certificate
of Incorporation of the Company and Section 145 of the General
Corporation Law of the State of Delaware (the "GCL"), as amended,
the Company is required to indemnify a director or officer of the
Company for expenses arising out of legal proceedings in which the
director or officer became involved by reason of his position as a
director or officer of the Company, if he acted in good faith and
in a manner he reasonably believed to be in or not opposed to the
best interests of the Company and, with respect to any criminal
proceedings, if he had no reasonable cause to believe his conduct
was unlawful. In a proceeding to procure a judgment in the
Company's favor, a director or officer may be indemnified for
expenses incurred by him in connection with the defense or
settlement of the suit if he acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interests
of the Company, except that no indemnification shall be permitted

<PAGE>
without a court order in respect of any claim, issue, or matter as
to which such director or officer shall have been adjudged to be
liable for negligence or misconduct in the performance of his duty
to the Company. Indemnification of a director or officer as
provided above, unless court-ordered, shall be made by the Company
only upon a determination that indemnification is proper in a
specific case because the conduct of such director or officer meets
the standards set forth above. Such determination shall be made
(i)by a vote of the majority of a quorum consisting of directors
who were not parties to the proceeding involved, (ii) by
independent legal counsel in a written opinion or (iii) by the
stockholders of the Company.

      Under agreements entered into by the Company and all of the
members of its Board of Directors, the foregoing indemnification
provisions have been supplemented as follows with respect to such
persons: (i) indemnification is permitted in the event the director
is wholly or partly successful; (ii) prompt payment of litigation
expenses is provided in advance of indemnification, subject to
repayment if it is subsequently determined that the director was
not entitled to indemnification for the expenses in question; (iii)
prompt indemnification is provided unless a determination is made
that the director has not met the applicable statutory standard;
(iv) in the event of a change in control of the Company, a
determination that indemnification is proper may be made solely by
independent legal counsel, in which case the indemnitee will be
presumed entitled to indemnification until such presumption is
overcome by the Company; and (v) the director is permitted to
petition a court or seek an award in arbitration with respect to
his entitlement to indemnification or advancement of expenses.

      Those members of the Board of Directors of the Company (the
"Prior IGL Directors") who previously were directors of Insituform
Group Limited ("IGL") are entitled to the benefits of the agreement
dated July 3, 1992 (the "IGL Acquisition Agreement") among the
Company, INA Acquisition Corp. ("INA Sub") and IGL, pursuant to
which INA Sub will honor and assume all obligations of IGL pursuant
to IGL's Articles of Association and Memorandum of Association as
in effect on July 3, 1992 which provide for indemnification of
directors of IGL with respect to events occurring prior to the
effective date of the acquisition of IGL by the Company. The
Company has also agreed to indemnify the Prior IGL Directors in
connection with certain actions taken as directors of IGL with
respect to the liquidation of IGL contemplated by the IGL
Acquisition Agreement.

      Those members of the Board of Directors of the Company (the
"Prior IMA Directors") who previously were directors of Insituform
Mid-America, Inc. ("IMA") are entitled to the benefits of the
agreement dated May 23, 1995 (the "IMA Merger Agreement") among the
Company, ITI Acquisition Corp. ("ITI Sub") and IMA, pursuant to

<PAGE>
which the Company and IMA, as a wholly-owned subsidiary of the
Company, will, to the extent permitted by the GCL and other law,
honor all obligations of IMA pursuant to IMA's certificate of
incorporation and by-laws, and certain agreements entered into by
IMA, as in effect on May 23, 1995, which provide for
indemnification of directors of IMA with respect to events
occurring prior to the effective time of the merger of ITI Sub into
IMA. Under agreements entered into by IMA and all of its directors
prior to May 23, 1995, IMA undertook to indemnify such individuals
to the full extent permitted by applicable law.

      In June 1988, the stockholders of the Company approved an
amendment to its Certificate of Incorporation to add a provision
which eliminates the personal liability of a director of the
Company to the Company or to any of its stockholders for monetary
damages for a breach of his fiduciary duty as a director, except in
the case where the director breached his duty of loyalty, failed to
act in good faith, engaged in intentional misconduct or knowingly
violated a law, authorized the payment of a dividend or approved a
stock repurchase in violation of Delaware corporate law, or
obtained an improper personal benefit or except for acts or
omissions occurring prior to June 17, 1988.


Item 7. Exemption from Registration Claimed
        -----------------------------------

      Not applicable.


Item 8. Exhibits
        --------

      The exhibits required to be filed as part of this Registration
Statement are listed in the attached Index to Exhibits.


Item 9. Undertakings
        ------------

      (a)   The undersigned Registrant hereby undertakes, except as
otherwise specifically provided in the rules of the Securities and
Exchange Commission promulgated under the Securities Act of 1933:

            (1)   To file, during any period in which offers or sales
are being made, a post-effective amendment to this registration
statement:

                  (i)   To include any prospectus required by section
      10(a)(3) of the Securities Act of 1933;


<PAGE>
                  (ii)  To reflect in the prospectus any facts or
      events arising after the effective date of the registration
      statement (or the most recent post-effective amendment
      thereof) which, individually or in the aggregate, represent a
      fundamental change in the information set forth in the
      registration statement. Notwithstanding the foregoing, any
      increase or decrease in volume of securities offered (if the
      total dollar value of securities offered would not exceed that
      which was registered) and any deviation from the low or high
      end of the estimated maximum offering range may be reflected
      in the form of prospectus filed with the Commission pursuant
      to Rule 424(b) if, in the aggregate, the changes in volume and
      price represent no more than a 20% change in the maximum
      aggregate offering price set forth in the "Calculation of
      Registration Fee" table in the effective registration
      statement;

                  (iii) To include any material information with
      respect to the plan of distribution not previously disclosed
      in the registration statement or any material change to such
      information in the registration statement;

      Provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do
not apply if the registration statement is on Form S-3, Form S-8 or
Form F-3, and the information required to be included in a post-
effective amendment by those paragraphs is contained in periodic
reports filed with or furnished to the Commission by the Registrant
pursuant to section 13 or section 15(d) of the Securities Exchange
Act of 1934 that are incorporated by reference in the registration
statement.

            (2)   That, for the purpose of determining any liability
under the Securities Act of 1933, each such post-effective
amendment shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of
such securities at that time shall be deemed to be the initial bona
fide offering thereof.

            (3)   To remove from registration by means of a post-
effective amendment any of the securities being registered which
remain unsold at the termination of the offering.

      (b)   The undersigned Registrant hereby undertakes that, for
purposes of determining any liability under the Securities Act of
1933, each filing of the Registrant's annual report pursuant to
section 13(a) or section 15(d) of the Securities Exchange Act of
1934 that is incorporated by reference in the registration
statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of
such securities at that time shall be deemed to be the initial bona
fide offering thereof.

      (c)   Insofar as indemnification for liabilities arising under
the Securities Act of 1933 may be permitted to directors, officers
and controlling persons of the Registrant pursuant to the foregoing
provisions, or otherwise, the Registrant has been advised that in
the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Act
and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by
the Registrant of expenses incurred or paid by a director, officer
or controlling person of the Registrant in the successful defense
of any action, suit or proceeding) is asserted by such director,
officer or controlling person in connection with the securities
being registered, the Registrant will, unless in the opinion of its
counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in
the Act and will be governed by the final adjudication of such
issue.

Item 4. Description of Securities
        -------------------------

      Not applicable.

Item 5. Interests of Named Experts and Counsel
        --------------------------------------

      The validity of the securities being offered hereby is being
passed upon for the Company by Krugman, Chapnick & Grimshaw, Park
80 West - Plaza Two, Saddle Brook, New Jersey 07663-5819. James D.
Krugman, a partner in Krugman, Chapnick & Grimshaw, is a director
and Chairman of the Board of the Company, and Howard Kailes, a
partner of such firm, is Secretary of the Company. Mr. Krugman owns
10,000 shares of Common Stock; is managing partner of a partnership
which owns 40,364 shares of Common Stock (in 5,046 shares of which
Mr. Krugman has a beneficial interest); has shared voting and
investment power over 33,300 shares of Common Stock owned by a
general partnership in which his mother has an interest; and has
the right to acquire 95,000 additional shares which are issuable
upon the exercise of options granted by the Company (of which
options covering 47,500 shares are currently exercisable).

Item 6. Indemnification of Directors and Officers
        -----------------------------------------

      Under the provisions of Paragraph Seventh of the Certificate
of Incorporation of the Company and Section 145 of the General
Corporation Law of the State of Delaware (the "GCL"), as amended,
the Company is required to indemnify a director or officer of the
Company for expenses arising out of legal proceedings in which the
director or officer became involved by reason of his position as a
director or officer of the Company, if he acted in good faith and
in a manner he reasonably believed to be in or not opposed to the
best interests of the Company and, with respect to any criminal
proceedings, if he had no reasonable cause to believe his conduct
was unlawful. In a proceeding to procure a judgment in the
Company's favor, a director or officer may be indemnified for
expenses incurred by him in connection with the defense or
settlement of the suit if he acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interests
of the Company, except that no indemnification shall be permitted
without a court order in respect of any claim, issue, or matter as
to which such director or officer shall have been adjudged to be
liable for negligence or misconduct in the performance of his duty
to the Company. Indemnification of a director or officer as
provided above, unless court-ordered, shall be made by the Company
only upon a determination that indemnification is proper in a
specific case because the conduct of such director or officer meets
the standards set forth above. Such determination shall be made
(i)by a vote of the majority of a quorum consisting of directors
who were not parties to the proceeding involved, (ii) by
independent legal counsel in a written opinion or (iii) by the
stockholders of the Company.

      Under agreements entered into by the Company and all of the
members of its Board of Directors, the foregoing indemnification
provisions have been supplemented as follows with respect to such
persons: (i) indemnification is permitted in the event the director
is wholly or partly successful; (ii) prompt payment of litigation
expenses is provided in advance of indemnification, subject to
repayment if it is subsequently determined that the director was
not entitled to indemnification for the expenses in question; (iii)
prompt indemnification is provided unless a determination is made
that the director has not met the applicable statutory standard;
(iv) in the event of a change in control of the Company, a
determination that indemnification is proper may be made solely by
independent legal counsel, in which case the indemnitee will be
presumed entitled to indemnification until such presumption is
overcome by the Company; and (v) the director is permitted to
petition a court or seek an award in arbitration with respect to
his entitlement to indemnification or advancement of expenses.

      Those members of the Board of Directors of the Company (the
"Prior IGL Directors") who previously were directors of Insituform
Group Limited ("IGL") are entitled to the benefits of the agreement
dated July 3, 1992 (the "IGL Acquisition Agreement") among the
Company, INA Acquisition Corp. ("INA Sub") and IGL, pursuant to
which INA Sub will honor and assume all obligations of IGL pursuant
to IGL's Articles of Association and Memorandum of Association as
in effect on July 3, 1992 which provide for indemnification of
directors of IGL with respect to events occurring prior to the
effective date of the acquisition of IGL by the Company. The
Company has also agreed to indemnify the Prior IGL Directors in
connection with certain actions taken as directors of IGL with
respect to the liquidation of IGL contemplated by the IGL
Acquisition Agreement.

      Those members of the Board of Directors of the Company (the
"Prior IMA Directors") who previously were directors of Insituform
Mid-America, Inc. ("IMA") are entitled to the benefits of the
agreement dated May 23, 1995 (the "IMA Merger Agreement") among the
Company, ITI Acquisition Corp. ("ITI Sub") and IMA, pursuant to
which the Company and IMA, as a wholly-owned subsidiary of the
Company, will, to the extent permitted by the GCL and other law,
honor all obligations of IMA pursuant to IMA's certificate of
incorporation and by-laws, and certain agreements entered into by
IMA, as in effect on May 23, 1995, which provide for
indemnification of directors of IMA with respect to events
occurring prior to the effective time of the merger of ITI Sub into
IMA. Under agreements entered into by IMA and all of its directors
prior to May 23, 1995, IMA undertook to indemnify such individuals
to the full extent permitted by applicable law.

      In June 1988, the stockholders of the Company approved an
amendment to its Certificate of Incorporation to add a provision
which eliminates the personal liability of a director of the
Company to the Company or to any of its stockholders for monetary
damages for a breach of his fiduciary duty as a director, except in
the case where the director breached his duty of loyalty, failed to
act in good faith, engaged in intentional misconduct or knowingly
violated a law, authorized the payment of a dividend or approved a
stock repurchase in violation of Delaware corporate law, or
obtained an improper personal benefit or except for acts or
omissions occurring prior to June 17, 1988.

Item 7. Exemption from Registration Claimed
        -----------------------------------

      Not applicable.

Item 8. Exhibits
        --------

      The exhibits required to be filed as part of this Registration
Statement are listed in the attached Index to Exhibits.

Item 9. Undertakings
        ------------

      (a)   The undersigned Registrant hereby undertakes, except as
otherwise specifically provided in the rules of the Securities and
Exchange Commission promulgated under the Securities Act of 1933:

            (1)   To file, during any period in which offers or sales
are being made, a post-effective amendment to this registration
statement:

                  (i)   To include any prospectus required by section
      10(a)(3) of the Securities Act of 1933;
(ii)  To reflect in the prospectus any facts or
      events arising after the effective date of the registration
      statement (or the most recent post-effective amendment
      thereof) which, individually or in the aggregate, represent a
      fundamental change in the information set forth in the
      registration statement. Notwithstanding the foregoing, any
      increase or decrease in volume of securities offered (if the
      total dollar value of securities offered would not exceed that
      which was registered) and any deviation from the low or high
      end of the estimated maximum offering range may be reflected
      in the form of prospectus filed with the Commission pursuant
      to Rule 424(b) if, in the aggregate, the changes in volume and
      price represent no more than a 20% change in the maximum
      aggregate offering price set forth in the "Calculation of
      Registration Fee" table in the effective registration
      statement;

                  (iii) To include any material information with
      respect to the plan of distribution not previously disclosed
      in the registration statement or any material change to such
      information in the registration statement;

      Provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do
not apply if the registration statement is on Form S-3, Form S-8 or
Form F-3, and the information required to be included in a post-
effective amendment by those paragraphs is contained in periodic
reports filed with or furnished to the Commission by the Registrant
pursuant to section 13 or section 15(d) of the Securities Exchange
Act of 1934 that are incorporated by reference in the registration
statement.

            (2)   That, for the purpose of determining any liability
under the Securities Act of 1933, each such post-effective
amendment shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of
such securities at that time shall be deemed to be the initial bona
fide offering thereof.

            (3)   To remove from registration by means of a post-
effective amendment any of the securities being registered which
remain unsold at the termination of the offering.

      (b)   The undersigned Registrant hereby undertakes that, for
purposes of determining any liability under the Securities Act of
1933, each filing of the Registrant's annual report pursuant to
section 13(a) or section 15(d) of the Securities Exchange Act of
1934 that is incorporated by reference in the registration
statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of
such securities at that time shall be deemed to be the initial bona
fide offering thereof.

      (c)   Insofar as indemnification for liabilities arising under
the Securities Act of 1933 may be permitted to directors, officers
and controlling persons of the Registrant pursuant to the foregoing
provisions, or otherwise, the Registrant has been advised that in
the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Act
and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by
the Registrant of expenses incurred or paid by a director, officer
or controlling person of the Registrant in the successful defense
of any action, suit or proceeding) is asserted by such director,
officer or controlling person in connection with the securities
being registered, the Registrant will, unless in the opinion of its
counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in
the Act and will be governed by the final adjudication of such
issue.
