Due to the COVID-19 pandemic, our office is closed to the public.  To avoid late fees, we encourage all of our customers to use our online bill payment solutions or call the office 925-625-3798 to make payment arrangements.

Staff is busy transitioning the District to a new financial management software system with new bill payment options.  The new online payment and water consumption portal will launch August 17th with new features for our customers.  Until then, look here for bill payment options.
