The purpose of Zone 2 Water Replacement Package project is to expand Charlotte Water’s ongoing water replacement program by expediting the replacement of older water mains that are of pipe materials known to have a high likelihood of failure. Through research of main break data, a group of neighborhoods have been identified with a high concentration of these water mains made from these pipe materials. This project will focus on the replacement of the galvanized steel pipe (GSP) and asbestos cement pipe (ACP) within the project area but will consider other mains within the scope areas as well if deemed necessary. For this project, Charlotte Water staff believes the Progressive Design-Build delivery method will be best.
Charlotte Water will be soliciting proposals from interested companies for siphon pipe inspection and cleaning services. Charlotte Water will be awarding a contract to perform planned siphon pipe inspections and cleaning on a re-occurring maintenance schedule with a standard frequency.
A Charlotte Water representative shall be present when the final cleaning runs are made to ensure cleanliness and will make the final decision on whether the cleaned siphon is acceptable or not. When available, construction drawings of the siphon(s) to be cleaned will be provided.
Charlotte Water, a Department of the City of Charlotte, will be soliciting Proposals from interested Companies for Sanitary Sewer Cleaning and Closed Circuit Television (CCTV) Inspection Services of sanitary sewer pipes, including flow control, within the Charlotte Water service area. To ensure that the wastewater service flows properly, the sanitary sewer system must be regularly checked to ensure continuous flow with limited interruptions and to assist in maintaining the infrastructure from various issues including: root intrusions, broken or cracked sanitary sewer lines, illegal connections, or other pipe damage from external causes. This solicitation will be comprised of two scopes of services, scheduled and on-call services.
Sanitary sewer pipes must be cleaned to within 99% of the original carrying (flow) capacity of the pipe. All grease, roots, and debris shall be completely removed to be considered clean.
