program accelerates investment in our nation's water
infrastructure by providing long-term, low-cost supplemental
loans for regionally and nationally significant projects.

PURE WATER SAM DIEGO

BORROWER: City of San Diego
LOCATION: San Diego, California

WIFIA LOAN AMOUNT: $614 million
TOTAL WIFIA PROJECT COSTS: $1.4 billion
POPULATION SERVED BY SYSTEM: 1,4 million people
NUMBER OF JOBS CREATED: 480 jobs

PROJECT DESCRIPTION

The City of San Diego will construct a new water reuse/recycling facility to produce 30 million
gallons per day (mgd) of purified water. This is the first phase in its multi-year Pure Water
Program that will use proven technology to clean non-potable reused/recycled water into safe,
high quality, drinking water and provide one-third of the City's water supply by 2035. This
purified reused/recycled water will blend with imported and locally sourced water and will be
treated again at the Miramar Water Treatment Plant before being distributed to the public. The
construction project will include new pump stations and conveyance systems, expansion of the
existing North City Water Reclamation Plant, and improvements to the existing Miramar
Reservoir Pump Station. This project will provide a reliable, sustainable supply sourced from
reused/recycled water, reduce the need for imported water, and divert wastewater flows away
from the Point Loma ocean discharge plant.

PROJECT BENEFITS
