Dear Fellow Stockholder:

Recently you may have received an unsigned, anonymous letter from an alleged
employee or employees of the California Water Service Group. The letter was
especially disturbing in its numerous factual inaccuracies, its racial attack on
those who have come to America from other countries, and its personal assault on
my colleague, Pete Nelson.

I speak on behalf of your Board of Directors when I express our complete
confidence in our President and Chief Executive Officer, Pete Nelson. His
breadth of experience, vision, and dedication to increasing shareholder value
and providing excellent customer service make him a critical asset to our
company and its long-term success. Moreover, I can assure you that the
California Water Service Group has the leadership, financial strength, and
strategy to continue its long history of exemplary performance.

Cal Water has always been known for its candor and its commitment to doing the
right thing for stockholders, customers, and employees. I know you share my
pride in all that the company has accomplished, and we look forward to reviewing
those accomplishments at our annual meeting in San Jose on April 24, 2002.

Thanking you for your confidence in the California Water Service Group and
hoping to see you in April, I am

Very truly yours,


/s/ Robert W. Foy

Robert W. Foy
Chairman of the Board
