Property owners use sump pumps to battle moisture and flooding issues. The basic sump pump system includes drain tile, a sump pit (which extends below the slab and collects surface water that enters the basement/crawl space or groundwater that rise to the slab), a sump pump, a float or switch, and a drain line. The drain line should direct sump water outside and onto your property without impacting adjacent properties.
What's the problem?
When the sump pump is connected directly to the sanitary sewer system, it adds a tremendous amount of storm water into the system. This is storm water (clean water) that does not need to be treated by the Wastewater Treatment Plant. In addition, the sanitary sewer system is not designed to handle this storm water. It will require the region to build larger and additional sewer pipes and treatment facilities, it raises sewer fees and utility rates for communities and property owners; and it can cause sewage backups into the buildings and sewage overflows into waterways and other environmentally sensitive areas.
The Metropolitan Council estimates up to 80% of I/I comes from private sources, including defective sewer service lines and improperly connected sump pumps, downspouts, and foundation drains. Excessive I/I increases the need to build larger and more expensive sewer pipes and treatment facilities.
What can you do?
- Inspect and repair damaged sewer service lines.
- Replace older clay pipes that are beyond their service life.
- Make sure sump pumps and building drains are not connected to the sanitary sewer system.
