Definition - What does Seeper mean?
A seeper is a leak in an underground sewer pipe, causing excess water to seep back into the sewer pipe adding to the flow through the pipe. Aging sewer pipes can deteriorate and crack, or even have a more catastrophic failure resulting in large ingress of water to the pipe. A seeper is the lowest category of leak with small amounts of water entering the sewer.
Trenchlesspedia explains Seeper
Sewer systems involve large networks of piping, which traverses long distances underground. Many systems have been in place for decades, and have been subject to wear and tear over time. When a sewer begins to leak, water seeps into the pipe and adds loading to the downstream treatment plants and piping network. Trenchless rehabilitation methods include the use of inspection equipment to identify leaks. CCTV inspections are proving effective to determine the scope of damage and the best repair technique. Repair techniques like cured-in-place pipes are commonly used for trenchless rehabilitation.
