Storm Water - Sump Pumps

Press Enter to show all options, press Tab go to next option

sump_pumpSump pumps must be pumped outside and not into the sanitary sewer.  Ideally sump pumps should be discharged onto grassy areas and hoses should not cross sidewalks or streets or otherwise impede vehicle or pedestrian traffic.  Care should also be taken not to discharge water toward neighboring properties.  

Sump pumps may not be discharged to the sanitary system (toilets, sinks, showers, and floor drains in your homes) according to City ordinances.

The sanitary sewer system is designed specifically to carry domestic and industrial wastewater and is operated separately from the storm sewer system. The storm sewer system, however, is designed to carry the runoff of storm water and is better designed to handle increased capacity.

In recent storms the sanitary system has faced increased volume of wastewater. This requires a higher cost of treatment and the potential for sanitary sewer backups or emergency discharges from the treatment plant.

Discharging sump pumps outdoors into the storm water system reduces the treatment costs and the potential for problems within the system itself.
