AGENDA TITLE: Approve Plans and Specifications and Authorize Advertisement for Bids for
Well 10C Rehabilitation Project
MEETING DATE: August 19, 2015
PREPARED BY: Public Works Director
RECOMMENDED ACTION: Approve plans and specifications and authorize advertisement for
bids for Well 10C Rehabilitation Project.
BACKGROUND INFORMATION: Well 10C is located at 790 North Guild Avenue and was constructed
in 2003. Since, the yield of the well has been reduced while the
production of sand particles has increased. The City hired a
contractor to remove the pump and perform video inspection in 2013. The video inspection shows the
well casing is encrusted with scale which is restricting the well screen openings. The video also reveals
more than 40 feet of silty type material at the bottom of the well.
The inspection of the pump equipment indicates sufficient wear and tear to warrant rebuilding the pump
to restore the water production rate. This project employs mechanical and chemical means to clean the
well casing of encrustation, remove debris from the bottom of the well, redevelop the well, and rebuild the
pump equipment to restore the yield of the well. The City needs this water well to supplement peak hour
demand and fire flows in the industrial area east of Highway 99. The water from the surface water
treatment facility would not be able to supply the water to this part of the City especially during fire
events.
This project consists of performing video inspection of the water well, cleaning the well casing,
rehabilitating the well to restore capacity, inspecting and rebuilding (if necessary) the existing deep well
turbine pump equipment, 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 September 16, 2015. The project estimate is $95,000.
FISCAL IMPACT: This project will reduce the long term maintenance cost of the water well.
FUNDING AVAILABLE: Funding will be identified at project award.
