Title
Murphree Water Treatment Plant (MWTP) Filter Expansion and Upgrade (B)
Staff recommends awarding a contract to Beach Construction Company, Inc. for construction services for the MWTP Filter Expansion and Upgrade.
Explanation
W/WW Systems has a Capital Improvements Program to fund various improvement projects at the Murphree WTP. Upon completion, this project will enhance the reliability, redundancy, and treatment capacity of the filtration treatment system. The project includes constructing two new filters (Filters No. 5 and No. 6) to increase filtration capacity. The two new filters will be constructed similar to the existing Filters No. 1 through No. 4 and will include a new pipe gallery, clearwell, influent channel, and an elevated walkway to connect the existing filter structure to the new filter structure. In addition, rehabilitation work will be performed on existing Filters No. 1, No. 2, No. 3, and No. 4 which will modify the filter media and instrumentation and electrical systems to enhance reliability and replace components that have reached their useful service life. This rehabilitation will include replacement of the filter sweep piping, construction of new baffle walls in the inlet channels to improve hydraulics, and repair minor cracks in concrete to existing filters.
