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.
