Cascal N.V. Files in Dutch Court

Applies for Immediate Relief to Protect Interest of Minority Shareholders

LONDON, June 3, 2010 - Cascal N.V. (NYSE: HOO) (The Company) announced that it filed an
application with the Court of Appeals Amsterdam Enterprise Chamber (the
"Court") on June 2, 2010 requesting that the Court grant preliminary relief
in order to protect the interest of its minority shareholders. The Court has
scheduled a hearing at 9:00 AM New York City time on June 10, 2010, ahead of
the expiration of the Sembcorp Tender Offer (the "Offer"), which currently
expires at 11:00 AM New York City time on June 21, 2010.

Cascal has serious objections to the Offer, including: the manner in
which the Offer was prepared, the below market value assigned to Cascal
shares and the Offer structure. The Company also objects to the unconditional
and irrevocable terms Biwater accepted by agreeing to tender its Cascal
shares to Sembcorp. As Cascal outlined in its filing with the Court, each of
these items conflicts with fundamental principles set forth under Dutch
corporate law and conflicts with the interests and fundamental obligations
towards Cascal and Cascal's minority shareholders.

Cascal has asked the Court to protect the rights of its minority
shareholders by, among other things: appointing a special trustee to
temporarily oversee Biwater's holdings in Cascal, or alternatively,
suspending Biwater's right to vote its shares or to tender its shares to
Sembcorp. The Company has asked the Court to maintain these provisions until
such time that Sembcorp has committed itself to guaranteeing a sufficient
number of independent members on Cascal's Board that have adequate approval
and veto rights on resolutions affecting the interests of Cascal's minority
shareholders. The Company has also asked that Sembcorp refrain from
cancelling Cascal's New York Stock Exchange (NYSE) listing and/or cancelling
Cascal's share registration with the Securities and Exchange Commission
(SEC). Additionally, Cascal petitioned the Court to suspend the Cascal
directors that are also affiliated with Biwater.

The Board of Directors has indicated that it is pursuing a number of
additional initiatives to protect the interests of stockholders against
Sembcorp's inadequate and coercive offer.
