Request a Storm Sewer Discharge

Discharges to the Storm Sewer System

Regulations regarding discharges to the storm sewer system can be complex and confusing. In addition to stormwater, many non-stormwater discharges can enter the storm sewer system. Some of these are allowed, some are not, and others may require city authorization and implementation of Best Management Practices.

Examples of non-stormwater discharges to the storm sewer system include draining a swimming pool, discharging water from a construction site or discharging wash water. The city generally approves of these types of discharges with a Discharge Authorization or through the Batch Discharge process.
