LADWP, in partnership with the LA Department of Public Works (LADPW), LA Sanitation (LASAN), and Bureau of Engineering (BOE), developed a series of reports that comprise the City of Los Angeles' Recycled Water Master Planning (RWMP). A total of five documents were produced: Groundwater Replenishment Master Planning Report, Groundwater Replenishment Treatment Pilot Study, Non-Potable Reuse Master Planning Report, Terminal Island Water Reclamation Plant Barrier Supplement and Non-Potable Reuse Concepts Report, and Long-Term Concepts Report. These documents outline the importance of local and sustainable water supplies as well as strategies to increase recycled water production.
Recycled Water Master Planning Fact Sheets
To contextualize the RWMP documents, the fact sheets below describe LADWP's recycled water system, strategies for growth of the recycled water program, and applications of recycled water in Los Angeles.
Recycled Water Master Planning - Executive Summary
Groundwater Replenishment (GWR) Master Planning Report
The Recycled Water Master Planning documents include an evaluation of groundwater replenishment (GWR) as an opportunity to further production and application of recycled water. The report examines facilities needed to purify recycled water for the replenishment of the San Fernando Groundwater Basin.
Non-Potable Reuse (NPR) Master Planning Report
The Recycled Water Master Planning documents include a non-potable reuse (NPR) Master Planning Report to research, identify, and develop a series of potential NPR projects that could be implemented across the City. The NPR GWR Master Planning Reports provide a framework to meet recycled water goals while offsetting imported water.
Groundwater Replenishment (GWR) Treatment Pilot Study Report
Complimenting the strategies outlined in the Recycled Water Master Planning documents, the GWR Pilot Study Report illustrates the advanced water purification processes being considered to produce recycled water for GWR supply. The Pilot study detailed results and recommendations of testing to be used as the basis for planning and design of a future Advanced Water Purification Facility (AWPF) fed with effluent from the Donald C. Tillman Water Reclamation Plant.
Long Term Water Supply Concepts Report
Recognizing the complexity of the implementation of recycled water projects, the Long Term Concepts Report encompasses proposed opportunities available to the City to increase recycled water to offset imported water supplies.
Terminal Island Water Reclamation Plant Barrier Supplement and NPR Concepts Report
In addition to the Recycled Water Master Planning Documents, the Terminal Island Water Reclamation Plant (TIWRP) Barrier Supplement and Non-Potable Reuse Concepts Report is a roadmap for expanding TIWRP to maximize recycled water production. The report evaluates the possibility of recycled water deliveries from TIWRP and recommends reliability measures consisting of contingency facilities to be used should any of the water supplies be interrupted.
Community Input Received as of September 2012
Outreach activities led by the City of Los Angeles during the development of the RWMP included: presenting to and receiving feedback from the Recycled Water Advisory Group (RWAG); briefings for City Council and other elected officials; one-on-one briefings with key stakeholders; presentations to neighborhood councils, community organizations, non-government organizations (NGOs), and business groups; conducting Recycled Water Forums through the City; holding Urban Water Management Plan Workshops; informing the LADWP and City of Los Angeles Department of Public Works, Bureau of Sanitation (BOS) employees; gathering written support, and; maintaining a stakeholder database. Stakeholder outreach continues as RWMP strategies are implemented.
Pure Water Los Angeles Master Plan
Pure Water Los Angeles is a long-term program created to develop a new, local water drinking supply by producing purified recycled water from wastewater treated at the Hyperion Water Reclamation Plant located in Playa Del Rey.
