Charlotte Water needs to establish an annual sanitary sewer siphon cleaning program to optimize system performance and prevent sanitary sewer overflows. Many of the siphons are difficult to clean and may require specialty cleaning and inspection equipment. The intent of this project is to clean each siphon in the collection system at least once every year.
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. Available siphon information, along with maps and as-builts, are found later in these specifications. 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.
This contract will service the Field Operations Division of Charlotte Water and will primarily focus on the annual cleaning and inspection of approximately fifty (50) inverted siphons throughout the Charlotte Water service area.
The Company will be required to clean and inspect all 50+ siphons within the contract time period and will be responsible for scheduling the work. In addition, the Company will be required to clean and TV at least two (2) gravity lines directly upstream and two (2) gravity lines directly downstream of each siphon. Diameter of these lines range from 8-inch to 54-inch.
Charlotte Water needs services to clean and inspect sanitary sewer siphons regularly to maintain system performance and prevent overflows. Many siphons are challenging to clean and may require specialized equipment and techniques. The work involves cleaning and inspecting siphons of various sizes and configurations throughout the service area, with verification of their conditions and layouts. Cleaning schedules will be flexible and may include work during nights, weekends, or holidays to reduce service disruptions. In addition to the siphons themselves, the adjacent gravity sewer lines upstream and downstream of each siphon will also be cleaned and inspected. These services are essential to ensure the reliability and proper functioning of the sewer collection system.
A company shall provide all materials, equipment, labor, and incidentals required to perform pipe patching for the purpose of repairing joints and offset joints, crowns, and service laterals with an ambient cure, fiberglass liner impregnated with thermosetting epoxy for laterals and main lines within Charlotte Water’s service area.
Pebblestone Storm Drainage Improvement Project consist of channel stabilization and a parking lot rebuilt. The improvements will include approximately 250 linear feet of bank hard stabilization and 170 linear feet of bank soft stabilization. In addition to the channel stabilization, sanitary sewer improvements are required. 180 linear feet of 10-inch and 32 linear feet of 16-inch ductile iron restrained joint sanitary sewer pipe. 180 linear feet of 16-inch and 20 linear feet of 24-inch steel encasement pipe.
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.
The Project consists of water and sewer repair for various streets, highways, parcels, and utility easements within Mecklenburg County.
This project will replace the signalized intersection of Tuckaseegee/Thrift/Berryhill with a roundabout.
This project will install sidewalk within the Peachtree Hills area in three (3) locations. The proposed sidewalk will be located along Peachtree Road from Oakdale Road to Crandon Drive, along the northeast side of Beam Lake Drive from Peachtree Road to an existing sidewalk connection 800ft east, and along the south side of Oak Drive from Oakdale Road to an existing sidewalk connection 0.25 miles east.
This project will be construct various small sidewalk and ramp improvements throughout the City of Charlotte.
