information required pursuant to Rule 13d-2 under the Securities Exchange Act of
1934, as amended, relating to the shares of common stock, par value $0.55 per
share, of the Issuer.

                  All capitalized terms used in this Amendment and not otherwise
defined herein have the meanings ascribed to such terms in the Schedule 13D.

Item 2.           Identity and Background.
                  ------------------------

                  The second paragraph of Item 2(a) is amended and restated in
its entirety as follows:

                  "Except for three (3) shares held indirectly by Vivendi

entirety as follows:

                  "The names, residence or business addresses and present

Item 5.           Interest in Securities of the Issuer.
                  ------------------------------------

                  Item 5 (a)-(c) of Schedule 13D is amended and restated in its
entirety as follows:

                  "(a) As of September 25, 2002, Vivendi Universal could be
deemed to be, through its 40.8% interest in Environnement, the beneficial owner
of 2,500,001 Shares held by Water. Vivendi Universal does not own any of the
Shares (other than through its interest in Environnement) and disclaims
beneficial ownership of any Shares. This Amendment may not be construed as an
admission by Vivendi Universal that it is the beneficial owner of any Shares. To
the best knowledge of Vivendi Universal, no director or executive officer owns
or has any right to acquire, directly or indirectly, any Shares.

                  As of September 25, 2002, Environnement was, through its
subsidiary Water, the beneficial owner of 2,500,001 Shares, constituting
approximately 3.6% of the outstanding Shares (based upon 68,858,761 shares
outstanding as of July 30, 2002 according to the Issuer's Quarterly Report on
Form 10-Q for the Quarter ended June 30, 2002). To the best knowledge of
Environnement, no director or executive officer owns or has any right to
acquire, directly or indirectly, any Shares, other than Andrew D. Seidel, a
member of the Management Board of Environnement, who currently owns 875 Shares.

                  As of September 25, 2002, Water was the beneficial owner of
2,500,001 Shares, constituting approximately 3.6% of the outstanding Shares
(based upon 68,858,761 shares outstanding as of July 30, 2002 according to the
Issuer's Quarterly Report on Form 10-Q for the Quarter ended June 30, 2002). To
the best knowledge of Water, no director or executive officer owns or has any
right to acquire, directly or indirectly, any Shares.

                  As of September 25, 2002, VNAC did not beneficially own any
Shares. To the best knowledge of VNAC, no director or executive officer owns or
has any right to acquire, directly or indirectly, any Shares.

                  (b) Environnement has, through its subsidiary Water, the
shared power to vote or direct the disposition of 2,500,001 Shares. Water has
the shared power to vote or direct the disposition of 2,500,001 Shares.

                  (c) Neither Vivendi Universal nor, to the best of Vivendi
Universal's knowledge, any executive officer or director of Vivendi Universal:
(a) owns, or has any right to acquire, directly or indirectly, any Shares or (b)
has, in the past sixty (60) days, effected any transactions in the Shares.

                  Neither Environnement nor, to the best of Environnement's
knowledge, any executive officer or supervisory board member of Environnement:
(a) owns, or has any right to acquire, directly or indirectly, any Shares or (b)
has, in the past sixty (60) days, effected any transactions in the Shares, other
than (i) 875 Shares owned by Andrew D. Seidel, a member of the Management Board

and UBS Warburg LLC (collectively, the "Underwriters") pursuant to an
underwriting agreement dated September 19, 2002 by and among the Underwriters,
the Issuer, Water and VNAC (the "Underwriting Agreement"), and (iii) 761,655
Shares sold by VNAC to the Underwriters pursuant to the Underwriting Agreement.

                  Neither VNAC nor, to the best of VNAC's knowledge, any
executive officer or director of VNAC: (a) owns, or has any right to acquire,
directly or indirectly, any Shares or (b) has, in the past sixty (60) days,
effected any transactions in the Shares, other than 761,655 Shares sold by VNAC
to the Underwriters pursuant to the Underwriting Agreement.

                  Neither Water nor, to the best of Water's knowledge, any
executive officer or supervisory board member of Water (a) owns, or has any
right to acquire, directly or indirectly, any Shares or (b) has, in the past
sixty (60) days, effected any transactions in the Shares, other than 7,834,220
Shares sold by VNAC to the Underwriters pursuant to the Underwriting Agreement."

Item 6.           Contracts, Arrangements, Understandings, or Relationships
                  ---------------------------------------------------------
                  with Respect to Securities of the Issuer.
                  ----------------------------------------

                  Item 6 of Schedule 13D is amended and restated in its entirety
as follows:

                  "On July 8, 2002, Environnement, Water, VNAC and the Issuer
entered into a Registration and Stock Purchase Agreement (the "Agreement")
relating to the Shares. Pursuant to the Agreement, on July 8, 2002 the Issuer
filed a Registration Statement on Form S-3 ("Registration Statement") with the
U.S. Securities and Exchange Commission ("Commission") for the resale of up to
9,885,256 Shares ("Registered Shares") by VNAC and Water, which was declared
effective by the Commission on September 19, 2002. Each of Water, VNAC and the
Issuer executed the Underwriting Agreement in the form attached to the Agreement
on September 19, 2002.

                  Pursuant to the Underwriting Agreement, on September 25, 2002
the Underwriters acquired 8,595,875 Shares from Water and VNAC at $18.25 per
Share (the "Offering Price"), less underwriting discounts and commission of
