San Juan Water District is working on several infrastructure improvement projects to meet state and federal regulations, add system resiliency, and improve service.  These projects include a variety of repairs and new construction projects which are described in our Capital Improvement Plan. These projects are typically funded by water rates paid by customers throughout our Wholesale and Retail service areas, property taxes and state and federal grants.

SJWD personnel are constantly looking for ways to reduce cost and maintain quality service, including with our CIP program.

2023/2024 Air Release Valve Replacement Project

The project includes replacing 45 air release valves (ARV) that are deficient (i.e. broken, not found, cannot be repaired) and/or where the vent opening is located below ground surface and to bring the vent above ground in order to be in compliance with California Code of Regulations, Title 22, Section §64576 Air-Release, Air Vacuum, and Combination Valves.  In locations where existing ARVs are located below ground in the street, the ARV’s will be relocated to the side of the street behind the sidewalk or curb in accordance with the District’s Standards. ARVs will be located within the existing public rights-of-way and easements. The project area boundary for the project is shown in figure below.
