Consent Decree Early Action Project (EAP) improvements to the West Columbia Pump Station began with an assessment which led to rebuilding with resilient and redundant features to ensure continuous operation during flooding. Operating costs and efficiency have greatly improved and the potential for development has been increased. The Congaree River Sewer Force Main CD EAP addressed capacity issues in the existing sewer system by adding a new sewer force main from the West Columbia Pump Station and 22,000 feet of 42-inch force main from the pump station past Granby Park, Rocky Branch and along the quarry road at Vulcan Materials. Operating costs and efficiency have greatly improved and the potential for development has been increased. Total Contract Value is $7,851,089.69.

The Saluda River Pump Station, the City of Columbia's third largest wastewater pump station, saw several improvements as part of this Consent Decree Early Action Project (EAP). The pump station's capacity, equipment, and downstream force main were upgraded to increase efficiency, reliability and reduce the potential for sanitary sewer overflows.
The Columbia Metro WWTP Influent Pump Station and Preliminary Treatment Facility Consent Decree Early Action Project (EAP) involved the design and construction of a new 150 million gallon per day Influent Pump Station and Preliminary Treatment Facility - the largest structures of their kind in SC. Following the upgrades, operating costs and efficiency have greatly improved and the potential for sanitary sewer overflow has been reduced.
The upgrades to Columbia Metro WWTP's Final Clarifiers (Numbers 1-10) in this Consent Decree Early Action Project (EAP) allowed the City to meet SCDHEC's effluent requirements and increase efficiency and reliability.
The improvements to the North Columbia Pump Station during this Consent Decree Early Action Project (EAP) improved its ability to handle solids in the influent stream and provide better access for pump removal. Operating costs and efficiency have improved and the potential for sanitary sewer overflow has been reduced.
Small Sewer CIP projects for properties that are annexed into the City during the year. Funding for specific projects as identified through the course of the fiscal year.
Sewer lines to be replaced as part of the streetscaping project.
The trunk line to be upgraded from Greenlawn to Burnside #1 Pump Station consists of approximately 7,000 LF of gravity sewer ranging in size from 12" - 24" using Ductile Iron and High Density Polyethene pipes. The project consisted of two phases. The first phase of the project was completed in July 2017. The second phase of the project was delayed due to easement considerations, and it has been submitted to Procurement for bidding in 2021.
During the course of a fiscal year, a number of emergency projects arise that are small in size, and generally are not known about at the start of the budgeting cycle. A project budget is needed to cover these projects so that very small projects or emergencies (collapsed lines, etc.) can be completed within the planned budget and completed quickly and efficiently.
This project proposes the replacement of sanitary sewer piping to upsize the existing piping from Manhole 19449MH to Manhole 25145MH for a distance of approximately 5,500 linear feet with new 24-inch diameter gravity sewer located along Kinley Creek from Harbison Boulevard to Piney Grove Road. This project was identified as part of the collection system hydraulic modeling study (Hazen and Sawyer, 2014). This project is classified as a capital investment because it includes the installation of new sewer lines.
The East Rocky Branch Sewer Improvements Phase 1 (Upper Phase) project consists of upsizing the existing piping for a distance of approximately 7,500 linear feet with new 36-inch diameter gravity sewer, generally located along Rocky Branch. The project begins in the Five Points area at the intersection of Santee Ave and Harden St and terminates at the intersection of Main St and Whaley St. This project was identified as part of the collection system hydraulic modeling study (Hazen and Sawyer, 2014).
Clean each digester, replace heat exchangers, rotary gas valves, pearth gas, waste gas burners, valves, piping, pumps, and appurtenances indentified in a recent asset assessment study. Total Current Contract Value is $747,069.41.
This project will be for construction of a new Maintenance and Storage Building.
SCDOT proposes to widen Leesburg Road from 719’ west S-88 (Fairmont Rd) to 705’ east of S-37 (Lower Richland Blvd) (Approx. 3.9 miles). The proposal includes improving 5 lanes (4 travel lanes with a center turn lane), adding curb and gutter, storm drainage and improving intersections.
The aging sewer system, increased number of work orders, I&I, and SSOs have made this sewer basin a priority for rehabilitation. This basin was selected in accordance with our EPA approved CSAP and IRP programs. A consultant will perform a sanitary sewer evaluation study and develop design and bid documents for gravity sewer rehabilitation in the Broad River 02 sewer basin.
The purpose of this project is to provide technical consulting support for a sewer line capacity enhancement project. The services performed as a part of this Scope of Service include evaluation of alternative alignments, engineering, design and construction services for upsizing the existing piping from Manhole 25844MH to 25871MH for a distance of approximately 8,000 linear feet. The existing 18-inch sewer will be replaced with new 36-inch diameter gravity sewer. The project limits and recommended sizing of the gravity sewer line were determined by the CITY and Hazen and Sawyer’s system hydraulic modeling study (Hazen and Sawyer, 2014), 2018 Collection System Master Plan, and ongoing 2020 Major Wastewater Collection and Transmission System (WCTS) Master Plan Updates.
