RFP/Call for Bids Note: 

The City of Pacific Grove (City) will complete construction of the Pacific Grove Local
Water Project (PGLWP) in 2017 via a design-build contract. The primary purpose of the
project is to produce and distribute high quality recycled water to replace potable water
used for non-potable water demands.
The project consists of a 0.25 million gallon per day (MGD) Water Recycling Facility
(WRF) for the production of 125 acre-feet per year (AFY) of non-potable water primarily
for landscape irrigation. Irrigation occurs primarily during the nighttime and early
morning hours to maximize water management efficiency and minimize public contact.
Other recycled water uses include toilet and urinal flushing, sewer flushing, street
sweeping and construction demands. The recycled irrigation water pumping system is
part of this WRF; the irrigation system is maintained by the Golf Course and Cemetery
Operator.
The project diverts municipal sewage flows from the existing 15-inch gravity sewer in
Asilomar Avenue, through a diversion / influent pump station, which pumps sewage to
the WRF. The WRF utilizes Membrane Bio-Reactor (MBR) technology to treat the
influent and produce Title 22 compliant effluent for unrestricted reuse.
The WRF is designed to treat between 0.025 and 0.25 MGD depending on the irrigation
water demand. During certain periods (wet weather season) it may be necessary to
cease production of reclaimed water and to operate in a biological process maintenance
mode. The City is required to comply with the Waste Discharge Requirements as
described in the Order No. R3-2016-0044 (Production Permit) and SWRCB Order WQ
2016-0068-DDW (Use Permit) Exhibit C. The City is also required to operate pursuant
to the City’s Recycled Water Program.
