Land Based Disposal Systems

The Indirect Discharge Permit Section issues permits for land-based sewage treatment and disposal systems greater than 6,499 gallons per day, including septic tanks and leachfields and also treatment plants and spray disposal systems, all of which use soil as part of the waste treatment process. Following primary, secondary or tertiary treatment, the soil provides final effluent renovation and polishing before it reaches groundwater and, eventually, surface water. This is in contrast to direct discharge systems, which generally discharge through a pipe directly to surface waters.

Land-based sewage treatment and disposal systems with design flows of less than 6,500 gallons per day (a.k.a. on-site systems) are regulated by the Regional Office Program.

The Indirect Discharge Section also issues permits for the land application of food processing wastes generated during the production of cheese, ice cream, beer and other food products. Land application occurs on farm fields or by discharge to farm digesters and manure pits, returning some of the nutrients back to the land.

The management of wastewater treatment residuals, such as septage and wastewater sludge (aka biosolids) is regulated by the Residuals Management Section.
