Water and Energy Efficiency Programs

The Home Energy Renovation Opportunity (HERO) and the Property Assessed Clean Energy (PACE) programs provide home and condominiums owners the opportunity to make water and energy improvements without out-of-pocket expenditures. The HERO program partners with local governments to make water efficient, energy efficient, and renewable energy products affordable for homeowners. PACE works with homeowners to finance the installation of water and energy improvements. Both programs provide up to 100 percent financing and allow property owners to pay for the water, energy and money saving improvements over time as a line item on the property tax bill.  Please see each program for eligibility and program details.

WaterSense Program

Otay Water District has been an EPA WaterSense partner since 2008. WaterSense is a partnership program sponsored by the U.S. Environmental Protection Agency. Its mission is to protect the future of our nation’s water supply by promoting and enhancing the market for water-efficient products and services. Saving water is easy—many products are already available for use, and it doesn’t require changing the way most of us live or do business. WaterSense labelled products are generally 20% more water efficient than similar products in the marketplace.
