Water Savings Incentive Program

This program pays $0.60 per 1,000 gallons saved annually. Any project that saves at least 10,000,000 gallons of water could qualify for WSIP funding.

The Water Savings Incentive Program (WSIP) is designed for non-residential customers improving their water efficiency through upgraded equipment or services that do not qualify for standard rebates. WSIP is unique because it provides an incentive based on the amount of water customers save. This “pay-for-performance” design lets customers implement custom projects for their sites.

Terms & Conditions

The Metropolitan Water District of Southern California is a consortium of 26 cities and water districts that provides drinking water to nearly 19 million people in parts of Los Angeles, Orange, San Diego, Riverside, San Bernardino and Ventura counties.

Examples of successful projects include:

  • Changing industrial process water system to capture, treat, and re-use wastewater.

  • Replacing water-using equipment with higher efficiency models in commercial facilities such as kitchens or laundries.

  • Upgrading existing irrigation systems or landscaping to improve water use efficiency for agricultural operations and large landscapes.

  • Contracting for water management services to improve landscape water efficiency.

  • Capturing condensation and using it to supplement cooling tower water supply for increased efficiency.

To be approved for a WSIP incentive, projects must meet the following requirements:

  • Save at least 10,000,000 gallons of water over the total project lifespan (up to 10 years)

  • Cannot include new construction

  • Cannot be installed prior to application approval

  • Cannot save potable water by replacing it with another water source such as recycled or well water.

  • Customers should have at least three years of water use history to establish a baseline for water use before project implementation.

  • Project improvements should exceed locally-applicable water efficiency standards for the devices, products, or technologies being installed or implemented

  • For Equipment-type projects:

    • Operate at least 5 years

    • Save water for the lifespan of the equipment

  • For Water-service management type projects:

    • Include third party contractual services for at least one year

SoCal Water$mart encourages customers to apply at least 2 months before they plan to implement their projects to ensure adequate time for the application process.

Customers who do not anticipate starting their projects within the next 12 months should wait to apply. However, they can contact SoCal Water$mart at or (888) 645-3301 to discuss their project.
