Maximize water reuse in North County, without being encumbered by jurisdictional boundaries
Why? Local supply diversification The D‐word
Project continues to evolve Changing regulatory
environment – recycled to reuse
Link demands for recycled water in North County to production capabilities

Project Overview:Funding to Date
Prop 84 Integrated Regional Water Management Planning Grants
Phase I ‐ Awarded $1.5 million for programmatic EIR, feasibility study, and outreach plan AND direct reimbursement to each partner for their agency’s chosen component
Phase II ‐ Awarded IRWM Round 2 funding $3.4 million for construction

Water Resources Reform & Development Act
Lobbying agreement executed with 8 of the 10 participating agencies
Lobbied in DC five times – Sen. Feinstein, Sen. Boxer, Rep. Peters, Rep. Hunter, Rep. Issa, Army Corps Division Chief Schwitchenberg
All very supportive of this effort Met with local Army Corps of Engineers office in 2013 &
2014 WRRDA has been signed by the President.
Section 1014, Section 7001 and WIFIA
Also continue to monitor Title XVI opportunities
Project Overview:Federal Funding Efforts (WRRDA)
![Page 18: Water Reuse Coalition](https://reader033.vdocuments.mx/reader033/viewer/2022052901/556983d9d8b42a32068b537e/html5/thumbnails/18.jpg)
Complete Programmatic EIR, Army Corps Feasibility Study for WRRDA, and public outreach plan Outreach plan will convey the message of the need for supply
diversification and the viability and safety of recycled water, IPR, and DPR
Construct suite of projects awarded IRWM Round 2 funding ($3.4M)
Continue the pursuit of state and federal funding including IRWM Round 4, WRRDA, and other funding mechanisms
Agencies to continue work on individual water resource development efforts with collective goals in mind
Next Steps

Connect recycled water supplies with recycled water demand throughout North County, including storage and IPR, possibly DPR
Create win/win situations for all agencies involved and the region as a whole
Partnership opportunities and sharing
Ultimate Objective
