Construction of a new wastewater treatment plant in South Mecklenburg County near Mint Hill. The construction consists of process piping, wastewater equipment installation, and electrical power and controls. The project shall also include provision of a temporary treatment plant during construction of the new plant.
Replacement of diffuser discs in aeration basins 3 and 4. Structural repairs in basins. Baffle installation and mixer rehabilitation.
Roofing Replacement of various Wastewater Treatment Plants’ structures: McDowell, Irwin, Sugar Creek and McAlpine. Replacement consists of complete tear off of existing roof down to substrate. Minor mechanical and electrical relocation/replacement work will be performed, if necessary.
Roofing Replacement of various Water Treatment Plants and Lift Stations. The Project consists of replacing roofing systems at Sharon Repump Station, Hoskins Booster Pump Station, and Plaza Booster Pump Station, as well as removing existing skylight and install clerestory and roof structure at Plaza Booster Pump Station and replacing the skylight at Idlewild Booster Pump Station. complete tear-off of the existing roof down to the substrate. Minor mechanical and electrical relocations and re-hook-ups are required.
This project consists of the replacement of low lift station pump check valves. The project will also include filter improvements and non-potable water upgrades, electrical updates, and a sluice gate replacement.

Charlotte Water (CLTWater) is seeking Progressive Design-Build services to assist with the analysis, design and construction of the Mallard Creek Interceptor Improvement Project – Phase 1 and 2 (Project). Proposers need to assemble a team of experts including at a design, survey, geotechnical, environmental, permitting, pre/post blasting surveys and related seismic monitoring, real estate acquisition including appraisal and legal, and communication experts and construction contractors.
The Mallard Creek Basin service area consists mainly of residential zoning, with increasing commercial development around the new Blue Line Extension, UNC Charlotte, and the University Research Park. Infrastructure improvements are needed, not only to support current flows and maintain required service levels within the Mallard Creek Basin, but to also keep pace with the rapid growth and development. Hydraulic modelling conducted for the Mallard Creek Basin indicated that the Mallard Creek interceptor is currently capacity limited under two-year peak flow conditions. Future population and flow projections further suggested that flows in the basin would likely grow about 20 percent every 10 years. Per Charlotte Water’s Capacity Assurance Program (CAP), for the purposes of accepting new connections, adequate capacity exists when the sanitary sewer system can convey flows at a 2-year Level of Service (LOS) between the point of connection and the wastewater treatment plant without excessive surcharge, while future enhancements are sized for the 10-year peak flow condition.
