This project will include the installation of 39 new valves inside of the 24 MOD. The existing valves have reached their useful life. These valves have been purchased separately by Charlotte Water.
Lee Dukes Alum Bulk Storage Replacement
This construction contract is for the replacement of the Alum Bulk Storage tanks at the Lee Dukes Water Treatment Plant. The project will also include replacement of the existing piping between the day tanks and the bulk storage and the piping between the bulk storage tank to the delivery fill location.
Lee Dukes Chemical Feed Piping Replacement
This construction contract will be for the replacement of the chemical feed piping at the Lee Dukes Water Treatment Plant. The piping replacement will pertain primarily to the chlorine feed system and the alum feeds.
Siphon Cleaning Services
Cleaning and post cleaning inspection services for various diameters, lengths and configurations of inverted siphons, including flow control, throughout the Charlotte Water service area. The diameters of siphon pipes to be cleaned and inspected range from 6-inch to 48-inch and include both single and multi-barrels. The Company shall verify the sizes and configurations of each siphon and report any discrepancies to the as-builts to Charlotte Water. Cleaning schedules will vary, as required, and may include the need to perform services during nights, weekends, and/or City observed holidays. Company awarded must have a vacuum truck to haul sewage debris to landfill.
Reclaimed Water Pumping Capacity Improvements at Mallard
This contract will provide services to improve reclaimed water pumping capacity at the Mallard facility. The improvements will enhance system efficiency and support increased demand for reclaimed water usage. Upgrades will include pump replacements and infrastructure modifications.
Multi-Sensor Inspections
The work consists of all labor, material, and equipment to inspect existing large diameter sewers using Multi-Sensor (Laser/LiDAR), Sonar, and HD Image technology. The MSI deployment shall provide a three-dimensional representation of internal pipe conditions above the flow line using laser/LiDAR measurement and below the flow line using sonar measurement and both combined with HD imaging. The work includes locating manhole using signal transmitting device, processing the MSI data and delivering the results of the processing in a ready to use format.
Zone 2 Water Replacement Package 1
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.
FY23 Professional Engineering and Land Survey Services for Watermain and Sanitary Sewer Street Main Design/Extensions Contract #1 – CANCELLED
This contract is for professional services in support of the Design and Construction Division. These contracts will allow Design and Construction to assist with LCR projects which typically require a longer and more complicated design process which in turn is more costly. Examples of reasons for increased cost in LCR projects versus typical street main extensions would be the need for geotechnical investigation or wetlands investigation and permitting.
Fiscal Year 22 Water Main Rehabilitation
This project will clean and apply a polymer coating to the interior walls of old, but still structurally sound cast iron water mains. Also included is the replacement of all valves, hydrants, and galvanized service lines associated with each project. The work completed in this contract will improve water quality and flow in the distribution system; consists of an undetermined number of individual projects consisting of water infrastructure rehabilitation; and/or replacements, which will be assigned by the Project Engineer.
