In an effort to further Mayor Eric Garcetti's water conservation goals, the City of Los Angeles’ Bureau of Engineering (Engineering) will forego using drinking water during the construction of the Sixth Street Viaduct and instead use water from the Los Angeles River. An estimated 13 million gallons of drinking water will be saved in a first of its kind partnership with the Los Angeles Department of Water and Power (LADWP).

"L.A. is still coping with the drought, and we cannot let up on finding innovative ways to conserve water," said Los Angeles Mayor Eric Garcetti. "Using river water for this project allows us to conserve our most precious resource while replacing aging infrastructure."

To make the switch to river water, Engineering has entered into a partnership with LADWP, the Los Angeles Regional Water Quality Control Board and the California Department of Fish and Wildlife, as well as the construction contractor, Stacy Skanska and Witbeck.

“Construction projects like the $445 million Sixth Street Viaduct Replacement Project need large amounts of water to control dust,” said Gary Lee Moore, Los Angeles City Engineer. “This partnership enables us to use available water and save drinking water for the residents of our city.”

The water is pumped directly from the river into water trucks. The trucks are then moved into position to spray water onto dust coming from the demolition of the viaduct. Water pumped from the river may also be used in the construction of the new bridge.

“Water conservation is a key priority and LADWP is always looking for new innovative ways to conserve drinking water for our customers who need it,” said David Wright, LADWP General Manager. “This partnership is a win-win for the City and for all of us.”
