CEO Stephane Richer Steps Down as a Director of Cascal N.V.

To remain CEO through July 31, 2010 and serve as an advisor thereafter

LONDON, June 7, 2010 - Cascal N.V. (NYSE: HOO) (the Company) today announced that Stephane
Richer is stepping down as a director of the Company but will continue in his
role as CEO until July 31, 2010. Thereafter, through March 31, 2011, Mr.
Richer will serve, as needed, as an advisor to the Company.

Mr. Richer, departing Cascal to return to France and pursue personal
interests, stated, "My departure from Cascal after eight years is a personal
decision. As the Company pursues its defense against the bid launched by
Sembcorp, I will continue to work with our Board, our management and our
advisors to serve the interests of our shareholders. Moreover, I stand ready
to provide advice and support to the Company as it seeks to execute on its
strategic and operating plans."

"The Board would like to express its gratitude and appreciation to
Stephane for his leadership and commitment to the success of Cascal. The
Company and its advisors will be working with him as Cascal defends the
interests of our shareholders against the inadequate and coercive bid by
Sembcorp. We also look forward to Stephane's leadership and support during
this transition period and wish him all the best in his future endeavors,"
stated Michael Wager, spokesperson for Cascal.

The Board expects to name a successor prior to Mr. Richer's July 31st
departure.
