The Folsom City Council on Tuesday unanimously approved a $474,041 agreement to begin engineering, design and inspection work tied to a major rehabilitation effort for one of the city’s key water storage facilities in the Broadstone area.
The council approved Resolution No. 11623 authorizing the city manager to execute an agreement with HydroScience Engineers, Inc. for the Zone 4 Tank Rehabilitation Project, a priority infrastructure effort aimed at maintaining long-term reliability within the city’s water distribution system.
The project centers on the city’s Zone 4 water storage tank on Caversham Drive in the Broadstone neighborhood. City officials identified the tank as a priority following structural concerns uncovered during ongoing rehabilitation work involving several other aging water tanks throughout Folsom.
Utilities Director Marcus Yasutake said the city’s ongoing infrastructure assessments and water master planning efforts have identified multiple aging facilities requiring rehabilitation or replacement to help ensure continued system reliability and water quality for residents.
Phase 1 of the project will involve draining and cleaning the tank so engineers can complete a detailed interior structural assessment. The work includes installation of scaffolding, sandblasting to expose structural steel components, inspections for corrosion and steel thickness, and identification of repairs necessary to extend the tank’s service life.
Additional improvements planned during the project include installation of a mixer and blower system designed to improve water quality, along with electrical upgrades and miscellaneous repairs. Similar improvements are also planned for East Tank No. 1 elsewhere in the city’s system.
City staff said the project timeline was accelerated after contractors encountered multiple unforeseen structural deficiencies during Folsom’s current Tower Tank Rehabilitation Project. Because the Broadstone tank is of similar age and construction type, officials determined it should be prioritized for further evaluation and rehabilitation planning.
HydroScience Engineers was selected following a competitive proposal process involving pre-qualified engineering firms. According to city documents, the company received the highest technical evaluation scores while also submitting a substantially lower proposal than a competing consultant. HydroScience’s proposal totaled $474,041 compared to another proposal exceeding $1.4 million.
City officials determined HydroScience provided the best overall value based on technical expertise, staffing, experience with similar projects and familiarity with Folsom’s water infrastructure system.
Construction tied to the first phase of the project is expected to begin later this year and continue through the winter of 2026-27 when water demand is lower and tanks can more easily be taken offline. Planning for a future Phase 2 rehabilitation effort is expected following completion of the structural assessments.
The project will be funded through the city’s Water Operating Fund and was approved as part of Tuesday’s consent calendar agenda.
