  • Small Flow Treatment Facilities Manual (PDF) (362-0300-002)

    This manual provides guidance for the design, permitting, installation, operation and maintenance of Small Flow Treatment Facilities. These facilities are intended to serve single-family residences, duplexes and small commercial establishments that generate 2,000 gallons per day (gpd) or less of domestic wastewater. The systems described in this manual may be eligible for coverage under an NPDES General Permit and Water Quality Management (WQM) General Permit. These general permits are published statewide one time and coverage is obtained under the statewide permit by documenting compliance with the provisions of this manual and a commitment to meet any conditions contained in the statewide permit. Proposals for systems not described in this manual must apply for individual NPDES and WQM permits that involve a more complex siting, design, and approval process.
