State Disposal System Permits

State disposal system permits are required for disposal of wastewater other than to surface waters, including large septic tank and drainfield systems and spray irrigation of wastewater. The need for an SDS permit may be satisfied by certain construction or operating practices; these must be evaluated on a case-by-case basis. Only domestic sewage should be discharged to drainfields.

Process wastewater, washwater and other wastewater should be discharged to a city sewer system. This may be a major consideration when siting a new industry.

Application forms are available from the MPCA at the address and telephone number listed in the Resource Directory section of this Guide. Applications should be submitted 180 days ahead of the anticipated beginning of construction. SDS permits are issued for a period of up to five years. There is an application fee and annual fees, which depend on the size of the facility.
