I NDEPENDENT A DVISORY PANEL
• Convened to provide expert peer
review of the technical, scientific,
and regulatory aspects of the
Demonstration Project
• Similar role as IAP for the City’s
Water Reuse Study & Orange
County’s Groundwater
Replenishment Project
• Provided feedback regarding
– San Vicente Reservoir
– AWP Facility
– Proposed regulatory framework
14
I NDEPENDENT A DVISORY PANEL
CONCLUSIONS
• Ten IAP meetings over three years
• IAP issued summary “letter of findings”
November 16, 2012
• Unanimously concluded the
Demonstration Project satisfied all City
Council directives, and a San Vicente
Reservoir augmentation project would
be a landmark project
“ . . .The Panel believes that
the … Report … (is) responsive
to the directives set forth by
the City Council.”
15
S AN V ICENTE R ESERVOIR S TUDY
• Reservoir provides an
environmental barrier that
satisfies anticipated regulatory
requirements
• Purified water will be diluted
at least 200:1 under all
anticipated reservoir operations
• Important aspects of water quality in San Vicente will not be
affected by adding purified water
• Reservoir expansion will improve water quality; purified water
will not substantially change this

L O N G - R A N G E W AT E R R ES O U R C ES P L A N 2 0 1 2 U P DAT E
E NERGY & E CONOMIC A NALYSIS
An Energy and Economic Analysis of various water supply
options and portfolios was performed through the LongRange Water Resources Plan (LRWRP) 2012 Update
• Energy consumption and greenhouse gas emissions of
purified water delivered to San Vicente comparable to that
of imported water
• Energy consumption and greenhouse gas emissions of
purified water lower than ocean desalination
