Reports & Planning Documents


As part of our commitment to transparency, we make it easy for residents of the Tri-Valley to access information about our water. This includes all required reports to meet state and federal guidelines, and additional reports, data, study results, presentations and other documents we make available for complete transparency.

This is your water agency. If you don’t see a document you are looking for, please feel free to submit a public records request to our Executive Assistant Donna Fabian.
