The Headworks DPR Remonstration Project: Implementing DPR for the City of LA

The City of Los Angeles (City) is implementing various strategies for developing a sustainable, local water supply portfolio. One of the key strategies includes a potential potable reuse project sourced from the Los Angeles-Glendale (LAG) Water Reclamation Plant (WRP), with purified water delivered directly to the potable water distribution system at Los Angeles Department of Water and Power (LADWP) Tom LaBonge Headworks Water Complex (Complex), as seen in Figure 1. This project, the LADWP Headworks Direct Potable Reuse (DPR) Project, would be considered DPR using an advanced water purification facility (AWPF) for treated drinking water augmentation (TDWA), as defined in the California State Water Resource Control Board (SWRCB) Proposed Framework for Regulating Direct Potable Reuse in California ñ Second Edition (SWRCB, 2019).
