BACKGROUND
Well 12 is located at the Phillips Ave Reservoir site. It has been inactive since 2018 due to poor water quality (i.e. 123 TCP).
Well 14 is located at the State Street Reservoir/Treatment Plant. It has been inactive for more than 20 years. The well was taken out of service due to poor water quality with multiple contaminants including high nitrate levels.
Well 17 was drilled in 2006, located at the Eastside Water Treatment Plant. However, it was not equipped for pumping.
Before bringing inactive Wells 12, and 14, into use with State Street Water Treatment Plant (WA212) and Well 17 Equipping (WA214) projects for Eastside Water Treatment Plant, the City initiated a CIP project to rehabilitate all three wells.
On January 4, 2022, the City Council awarded Construction Contract No. 2022-242 to General Pump Company, Inc. (GP) for the Rehabilitation of Wells 12, 14, and 17 for $2,936,100.
Since July 2023, GP has continued periodically pumping all three wells to limit biological growth on the well casing walls prior to construction of permanent pumps.
On May 6, 2025, City Council awarded Construction Contract No. 2025-264 to Pacific Hydrotech Corporation for the State Street Water Treatment Plant (WA212). The contract includes the contractor’s responsibility to maintain Well 12 and Well 14 prior to installing permanent pumps and connecting them to the City’s new water treatment plant.
In Summer 2026, the City plans to advertise Well 17 Equipping (WA214) for construction. The contract will include equipping Well 17 with a permanent pump for operational use and connecting it to the existing Eastside Water Treatment Plant at the same site. With the construction phase approaching, GP will no longer be contracted to maintain Well 17.
ISSUES/ANALYSIS
All work has been completed per the terms of the original construction contract and approved change orders. Change Order No. 1 updated the scope of work to include installation of temporary well pumps, equipment to perform maintenance flushing activities, and adjusting contract bid items to reflect a reduced project scope. Change Order No. 2 is the final balancing change order addressing changes in quantities to reflect actual work performed.
General Pump Company, Inc. has complied with the terms of the contract. A Notice of Completion has been prepared for filing with the San Bernardino County Recorder’s Office. The retention funds will be released following the 30-day period.
