3. North San Diego Water Reuse
Coalition

5. Project Overview: Goals
 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

Potable Reuse Opportunities:
 San Elijo Valley Basin
 San Dieguito Basin
 Mission Basin
 Escondido Valley Basin
 San Marcos Basin
 Suitable Surface Reservoirs Also Identified

15. Potable Reuse Efforts
 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)

16. 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

17. Project Overview:
Federal Funding Efforts (WRRDA)
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

18. Next Steps
 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

19. Ultimate Objective
 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
