Who We Are What we are trying to accomplish & Why Goals – Have changed over time Accomplishments
Where we are headed All options on the table
Recycled Water (purple pipe) Seasonal Storage Potable Reuse
Overview
North San Diego Water Reuse Coalition
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

North San Diego Recycled Water Coalition Support Hosted workshop for electeds on IPR/DPR Fund research efforts associated WateReuse DPR
initiative at $100,000 level Direct Potable Reuse initiative SB322 (Hueso) (2013)
Requires Dept. Public Health to develop potable reuse regulations
Final groundwater recharge regulations in 2014 Final surface water augmentation regulations by 2016 (expert panel)
Report to legislature on feasibility of DPR by 2016 (expert panel)
Potable Reuse Efforts
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)
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
Thank you!
