Construction has begun on two sanitation projects in the San Fernando Valley to tackle industrial groundwater pollution in the area after World War II and the Cold War era.
Developed by two companies and working as the Kiewit-Stantec design-build team on behalf of the LA Department of Water and Power for $ 400 million, the projects will enable groundwater remediation in the 226 square mile San Fernando Valley Groundwater base for several years according to the company.
LADWP is completing the projects, according to the company, in accordance with federal superfund legislation, which uses tax revenues from the chemical and petroleum industries to clean up dangerous sites.
The Central Response Action Treatment Facility in North Hollywood and the Tujunga Well Field Response Action Treatment Facility will be state-of-the-art by their completion in mid-2023, according to Stantec.
The systems will treat and deliver up to 75 million gallons of water per day.
The cleanup, the official said, will ultimately protect public health and strengthen the LADWP’s annual water rights and goals to reduce reliance on imported water.
Currently, local groundwater accounts for around 11% of the city’s total water supply – even more in times of drought.
“Just a year after design began, we are excited to see the inaugural construction work on the North Hollywood Central Reaction Treatment Plant and Tujunga Well Field Reaction Treatment Plant,” said Mike Watson, senior vice president of Stantec, in a statement announcing the construction. “This is an important step in providing Los Angeles residents and businesses with clean and reliable drinking water. “
The two companies bring design, construction and engineering together. According to the company, Stantec will provide services in the fields of construction, mechanics, construction mechanics, construction, architecture, landscape architecture as well as instrument and control technology. And Kiewit will provide electrical engineering services, as well as the management of construction activities.
