Earlewood Water System Improv, Columbia, SC

Improved Water Quality for a Historic Neighborhood

Hussey Gay Bell designed one of the City’s top water quality projects to improve the aging water distribution systems in the historic Earlewood neighborhood which seeks to provide high-quality water for its over 2,000 residents, reduce the number of water main repairs, and increase the available fire protection within the proposed project area. The approximate amount of replacement included 7,500 LF of 12-inch ductile iron pipe, 7,900 LF of 8-inch ductile iron pipe and 12,200 LF of 6-inch ductile iron pipe, totaling over 27,600 LF of corroded and irreparable water lines. Evaluation of alternative routes for the water lines and confirmation of capacity needs and issues were also included in the design.

Scope of work included hydraulic modeling; analysis of pressure piping; layout, calculations and analysis of new facilities; design and preparation of plans and specifications for water and wastewater infrastructure facilities to include civil; as well as water CAD modeling, pavement overlay design, geotechnical and public involvement.

The water system improvements for the Earlewood neighborhood will reach completion in 2018. This project demonstrates Hussey Gay Bell’s experience with replacing existing water and wastewater system components in a historic residential neighborhood via open-cut installation. This project required extensive coordination with the City of Columbia's engineering staff to determine capacity requirements and evaluate alternate routes for the piping, maintenance of service for residents and public involvement.
