Carollo Engineers Leading Historic Water Planning Effort: "One Water LA 2040"

Carollo Engineers is partnering with the Los Angeles Bureau of Sanitation (LASAN) and the Los Angeles Department of Water and Power (LADWP) to develop and implement the City's “One Water LA 2040” Plan.

"Los Angeles is pivoting away from its traditional reliance on climate-sensitive imported water supplies to focus on expanding its local water sources, in particular recycled water, groundwater, and runoff capture,” said Tom West, Carollo's project manager. "Through the One Water LA 2040 Plan, the City will build resiliency into every aspect of water — a goal that requires unprecedented collaboration between City departments, regional agencies, and stakeholder groups. We are pleased and proud to be a part of this historic endeavor.”

Over the next 12 months, Carollo's work on the One Water LA 2040 Plan will provide the framework, vision, and implementation strategy required to meet the region's near- and long-term water supply challenges. Specific objectives include:

  • Coordinating water management activities between all city departments, partners, and stakeholders.
  • Improving the health of local watersheds by restoring ecosystems, reducing pollutants in waterways, and returning water to local aquifers.
  • Planning for climate change through adaptation strategies.
  • Increasing community awareness and advocacy.
  • Optimizing more than $10 billion in capital improvement programs for wastewater, recycled water, and stormwater facilities.

As the City's overall Project Manager for the One Water LA Program, Carollo is developing wastewater and stormwater facilities’ master plans and city policies designed to govern on-site water conservation and reclamation. In addition, Carollo is directing stakeholder outreach and communications programs to engage more than 80 neighborhood councils, 15 council districts and more than a dozen local, state and federal agencies that represent the City's four million residents.

"The One Water LA 2040 Plan is an enormous undertaking,involving the coordination of multiple stakeholders, city departments and interest groups," said Adel Hagekhalil, assistant director for LASAN. “In the end, One Water LA will ensure the relationship that future generations of residents and ratepayers have with all aspects of water in Los Angeles will be the most reliable, cost-effective, environmentally sound and as healthy as possible. Through One Water LA we are connecting the dots, drops, and hearts of those we serve.”

Once complete, One Water LA will set the standard for integrated approaches to water management across a vast range of residential, commercial, and environmental demands.With the City's population expected to dramatically increase over the next 20 years, Los Angeles' city leaders will use the One Water LA Plan to squeeze value from every drop of the region's precious water resources.

“I am pleased with the high level of cooperation and collaboration that One Water LA is achieving between city departments,” said Martin Adams, senior assistant general manager of the Water System for LADWP. “The success of our future water supply portfolio benefits greatly from the close working relationship with LASAN. The One Water LA program is helping to facilitate that process and ensure that investments we each make are working toward a common goal.”
