Water infrastructure investment represents $250 million in savings, and prevents the annual loss of more than 300 million gallons of water.
WASHINGTON, D.C. – August 12, 2015 – (RealEstateRama) — Mayor Eric Garcetti today released 20,000 “shade balls” onto the surface of the Los Angeles Reservoir, marking completion of a $34.5 million initiative to protect the city’s water quality.
LADWP is the first utility company to use this technology for water quality protection. Today’s deployment marked the final phase of an effort that involves the deployment of 96 million shade balls to the 175-acre reservoir — the largest in-basin facility of its kind owned and managed by LADWP. The small, black plastic balls protect water quality by preventing sunlight-triggered chemical reactions, deterring birds and other wildlife, and protecting water from rain and wind-blown dust.
A cost-effective investment that brings the L.A. Reservoir into compliance with new federal water quality mandates, the shade balls are expected to save $250 million when compared to other comparable tools considered to meet that goal. Those alternatives included splitting the reservoir into two with a bisecting dam; and installing two floating covers that would have cost more than $300 million. In addition, the shade balls will also prevent the annual loss to evaporation of about 300 million gallons of water.
