Siphon Cleaning Service
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.
