The city relies on groundwater supplies for a portion of its drinking water. At an estimated cost of $500 million, the new AWPF will treat tertiary effluent from the existing Donald C. Tillman Water Reclamation Plant to produce purified water suitable for groundwater replenishment via the Hansen Spreading Grounds. The project will use advanced treatment processes, including microfiltration, reverse osmosis, and ultraviolet and advanced oxidation to purify more than 15 million gallons per day, reducing the amount of imported water, providing a new groundwater supply source for up to 200,000 customers, and helping to increase the city's resiliency by providing a sustainable local drinking water source in the traditionally drought-stressed region.
"Jacobs' selection by LASAN and LADWP to help secure the city's long-term water supplies with a new advanced water purification facility is one of several transformative projects happening in the state to address drought concerns in California," said Ron Williams, Jacobs People & Places Solutions Americas Senior Vice President. "Water scarcity is a growing issue across the globe. Taking this innovative and collaborative approach to tackle water shortages in Los Angeles offers a safe, sustainable, and effective way to manage water resources and address water scarcity issues in the state."
Jacobs has more than 25 years of experience in the water design-build space and has delivered more than 150 design-build projects and programs. Jacobs will deliver the project under a progressive design-build contract, with responsibility for design, permitting, construction, start-up, and commissioning. The city selected the progressive design-build delivery model to minimize cost, reduce risk, streamline construction, and improve schedule performance.
Because of the project's magnitude and importance in addressing water shortages in LA, it has received funding through the Water Infrastructure Finance and Innovation Act (WIFIA) program. WIFIA fast-tracks investment in U.S. water infrastructure by providing long-term, low-cost loans for regionally and nationally significant water projects. Financing the project with a WIFIA loan will save the city an estimated $81 million.
