RECOMMENDED ACTION Approve plans and specifications and authorize advertisement for
bids for Water Well Rehabilitation Project at Various Locations.
BACKGROUND INFORMATION:The proposed project is to rehabilitate two domestic water wells
(Well 1'1R and Well22) inside City limits and the Mosquito Pond
well at the White Slough Water Pollution Control Facility.
Well 1 1 R is located al 824 East Turner Road and was constructed in 1991 . Well 22 is located at 2001
South Cherokee Lane and was constructed in 1988. The water production at both wells has steadily
declined over the past several years, causing pumping water levels to approach the pump intake
elevation. While water wells can produce the desired amount of groundwater for decades, overtime, the
well casing openings can be encrusted with deposits, which need to be cleaned and removed in order to
restore the water production. The pumps also are expected to need replacement. These two water wells
(and the respective pumps) have exceeded the typical 2)-year design life and should be rehabilitated in
order to restore the well production.
The Mosquito Pond well is located at the city's wastewater treatment facility. lt is primarily used to
provide water to the San Joaquin County mosquito fish ponds. Occasionally, it supplies cooling water to
the Northern California Power Agency Lodi Energy Center. A steady decline in water production and
reliability prompted a recent inspection of the well. The inspection indicated the casing is damaged,
portions of the slotted casing are encrusted, and the bottom of the well is filled with sand and other debris
that needs to be removed. The water pump is also in need of replacement.
This project includes video inspection of the wells, mechanical and chemical removal of the encrustation
present on the well casing, removing the debris from the bottom of the well, furnishing and installing new
pump equipment to restore production, and other incidental and related work, all as shown on the plans
and specifications for the project.
The plans and specifications are on file in the Public Works Department. The planned bid opening date
is November 4,2020. The project estimate is $410,000.
FISCAL IMPACT:This project will reduce the long{erm maintenance costs of the water well
and enhance water system production capacity.
