A wastewater discharge permit is a document that outlines what type of waste and what quantity and strength you can discharge this waste to the sanitary sewer. There is no fee to obtain a permit, but depending on your operation type, surcharges to your monthly sewer bill, City staff time, and sampling may come at a cost.

You must obtain a wastewater discharge permit before the beginning of discharges into the sanitary sewer. You must apply at least 60 days before any planned discharges begin. Failure to do so can result in the suspension of your sewer service or civil penalties.

If you are already discharging wastewater regularly and believe you need a discharge permit, please contact the Industrial Waste Division, (916) 746-1882 or by email.

You can get additional details under the Roseville Municipal Code (RMC 14.26) or by contacting the Industrial Waste Division, (916) 746-1882 or by email.

The City of Roseville owns and operates two wastewater treatment plants, Dry Creek and Pleasant Grove. These facilities collect sewage from a large swathe of Southern Placer County (South Placer Municipal Utility District and County of Placer SMD 3-Horseshoe Bar, SMD2- Granite Bay, Dry Creek CSA, and the Sunset Industrial District.)

Discharges to the sewer must be of a quality that does not pose a hazard to the local environment, City staff, and the public. The operation of a “pretreatment program” (where the requirement of a discharge permit stems from) is stated in both the Dry Creek and Pleasant Grove’s NPDES permits issued by California.

Pollutants that cannot be treated in our treatment process may result in violations of these permits and heavy penalties on the City. These penalties may then increase the cost for all users of the sanitary sewer system. The City wishes to protect the environment at an affordable cost to all our customers.
