Prop 84 2015 IRWM Implementation Grant agreement provides funding from the Safe Drinking Water, Water Quality and Supply, Flood Control, River and Coastal Protection Bond Act of 2006 to GWMA for 19 projects located within the Greater Los Angeles IRWM region.
Gateway Water Management Authority (GWMA) is the Implementing Agency on the following projects:
Advanced Water Meter Replacement Project:
The project will save approximately 423 acre-feet per year (AFY) of water supply and improve regional water use efficiency by replacing an estimated 4,199 water meters at customer service connections with Advanced Meter Reading (AMR) units that have advanced reading technology capabilities. The project encompasses the service areas of 11 participating GWMA entities including the cities of Bellflower, Cerritos, Commerce, Downey, Lakewood, Norwalk, South Gate, and Whittier, as well as the Pico Rivera Water Authority, Long Beach Water Department and the Pico Water District.
Southeast Water Efficiency Program:
The project will improve water use efficiency by conducting audits to determine excess water use and implementing retrofits to offer immediate drought relief and long-term water savings at public facilities throughout the Central Basin service area. The project primarily targets the disadvantaged communities (DACs) in the Central Basin service area for the audits and retrofits. Devices that will be available for installation include high-efficiency toilets (tanks and flushometers), zero water and ultra-low water urinals, laminar flow restrictors, large rotary nozzles, rotating nozzles for spray heads, weather-based irrigation controllers, central computer irrigation controllers, and flow regulators. This project will save an estimated 176 AFY of water and provide a water quality benefit of reducing approximately 0.29 milligrams per liter (mg/L) per year of nitrate/nitrite.
Gateway Cities Regional Recycled Water System Expansion Project:
The project includes the planning, design, and environmental documentation for pipelines that will extend the Central Basin Municipal Water District (CBMWD) recycled water system into three cities, the City of South Gate, the City of Bell Gardens, and the City of Lynwood. The new customers that will be served include parks and schools in the disadvantaged communities (DACs) of the three cities. The project will provide 453 AFY of water savings and water quality improvement.
Paramount Blvd. Turf Replacement Project (Lakewood):
The project includes replacing turf with water-efficient and drought-tolerant landscaping, installing a water efficient irrigation system, and installing biofiltration swales along several roadway medians. These improvements will be implemented on approximately 100,000 square feet of median islands along Paramount Boulevard from Del Amo Boulevard to Carson Street. The project will provide an estimated 165 AFY of water savings and will improve water quality by reducing zinc concentrations in stormwater runoff.
