Discharge Requests

Questions regarding discharges to the storm and sanitary sewer? 

If you have a question regarding disposal of stormwater, wastewater or other material to the storm or sanitary sewer you can get guidance and approval from the Environmental Services Environmental Compliance Division (ECD). Some discharges are allowed without restrictions, while others may not be allowed or require a permit or authorization from the ECD. If a discharge requires an authorization, you may need to fill out a batch discharge request form to obtain approval. This may result in the requirement to sample and test the material or implement Best Management Practices. The ECD can provide you with information you need to appropriately dispose of materials and comply with federal, state, and local regulations.
