In 1992, the City of Santa Ana began receiving recycled water from the Orange County Water District
(OCWD) recycled water program /system called the Green Acres Project (GAP). GAP is a water reuse
effort that provides recycled water for landscape irrigation at parks, schools, and golf courses;
industrial uses, such as carpet dying; toilet flushing; and cooling for power generation. The GAP
recycled water production (treatment) facility is located in Fountain Valley. Recycled water similar to
the water produced by the GAP is commonly called "Purple Pipe" water. Currently recycled water
from the GAP is provided by OCWD to the following water purveyors for use in their service areas:
City of Fountain Valley Mesa Water District City of Newport Beach
City of Huntington Beach City of Santa Ana
Exhibit 1 is a map of the GAP distribution system and its major facilities. The system consists of a 7.5
Million Gallon /Day treatment plant, a 5.0 Million Gallon reservoir, pump station, 37 miles of distribution
pipelines, and 107 active services.
By agreement, the GAP recycled water wholesale rate is 80% of groundwater (water from
underground springs and wells) cost, and retail rates are capped at 80% of potable (water suitable for
drinking) water retail rates. This discount makes recycled water an attractive option for high volume
irrigators and certain industrial users. The OCWD is in the process of renewing the GAP Sales and
Distribution agreements with its retailers, and it is anticipated that the recycled water price will change
in the near future.
The City of Santa Ana utilizes 8% of GAP output (347 acre feet per year) at 25 metered connections.
The recycled water consumed by these accounts directly supplants potable water use, which reduces
the demand on the groundwater basin and preserves potable supplies for other uses. These accounts
combined save between $86,000 and $170,000 per year with recycled water. Recycled water use in
Santa Ana encompasses the irrigation of City Parks, Schools, Street Medians, some retail green
belts, Santa Ana River green belt, and carpet dyeing. During the development of the system, users

were connected based on their annual water demand, use compatibility, and proximity to the project's
recycled water mains. As shown in Exhibit 2, in Santa Ana the recycled water availability is limited to
the southwest quarter of the City along several major roads, where OCWD recycled water mains are
accessible. Exhibit 3 lists the current GAP recycled water users in the City, along with their estimated
annual average use in acre feet.
One of the main uses of the Recycled Water produced by the GAP program is the irrigation of public
street medians; however, major Recycled Water piping and boosting systems will be need to be built
to bring the water to where it is needed, if raw source water is available.
It is the policy of OCWD to maximize the production of the ultrapure water used to replenish the
groundwater aquifer through the Groundwater Replenishment System, which limits the production of
recycled water through the GAP program. In addition, the existing GAP treatment plant is limited in
capacity and will need major treatment process modification to accommodate major system
expansions. At this time, OCWD has no plans to expand the GAP recycled water mains for additional
capacity. Any expansion of the GAP system will have to be funded by the City or the end user.
STRATEGIC PLAN ALIGNMENT
