City Of Columbia

Project Description: City of Columbia owns and operates 56 pump station in its sewer collection system including six (6) major pump stations. As part of the Clean Water 2020 program, the City is making improvements to the pump stations to comply with the consent decree. The typical improvements includes old equipment removal, installation of new pumps, piping, generator, wetwell, control panels, and fencing, etc. Currently the City is undertaking a forcemain condition assessment project at selected major pump stations and a Supervisory
Control and Data Acquisition (SCADA) improvement project for all pump stations, through a Capital Improvement Project SS7333. Separately, the City is undertaking another project (SS7060), making improvements at six pump stations.

Although the above referenced projects addresses the vulnerability of having sanitary sewer overflows (SSO) at selected pump stations, the remaining pump stations poses risks (SSO, curtailing growth, aging infrastructure, etc.).

This project, based on the criticality, will select a handful of pump stations slated for improvements each fiscal year until all of the necessary improvements were carried out at remaining pump stations. Total Current Contract Value is $1,000,000.00.
