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.
