A 1 inch rainfall on the City of Summit generates approximately 105 million gallons of water. Some is absorbed into green spaces while the rest is discharged to three (3) of the State's Watershed Management Areas. The runoff is conveyed to these WMA's through the City's storm sewer network and discharged at 105 individual outfalls.
The City has thirteen (13) individual sub-watershed areas which are depicted on our the Watershed Map (PDF).
Citywide Drainage Assessment Report (DAR)
This report is used as infrastructure management tool to provide a guide for capital planning on drainage projects. It is revised annually in November to reflect new projects that have been identified and to remove projects that have been completed. Read the current report (PDF).
The "Stormwater Management Rules (NJAC 7:8)" were adopted February 2, 2004. The rules were adopted to conform to the December 1999 Phase II Rules by the EPA which followed up to the 1972 Clean Water Act. The State's Stormwater FAQ page provides specific details on the adopted rules.
The rules require each Municipality to obtain a permit to discharge runoff to the watershed. The permit is renewed annually.
Sump Pump Discharge Is Stormwater Not Sewage
Sump pumps are by law Not permitted to be connected to the sanitary sewer system. This overburdens a system not intended for heavier flows during wet periods and adds to Summit’s cost for treating sewage. Discharging sump pump flow onto City streets often causes icing hazards in the cold weather months for drivers and pedestrians. When such icing is deemed a hazard, the connection must be removed.
Therefore, sump pumps must be connected to the City’s storm sewer system where available or must discharge onto private property away from the building’s foundation.
