This advisory affects any property owner with a subsurface sewage disposal system (also known as septic systems, or septic tanks) or multiple systems for which the aggregate wastewater design flow is in excess of 2,000 gallons per day (GPD), regulated in accordance with the New Jersey Pollutant Discharge Elimination System (NJPDES) rules, N.J.A.C. 7:14A-1 et seq., and the Standards for Individual Subsurface Sewage Disposal Systems, N.J.A.C. 7:9A-1 et seq.
Subsurface sewage disposal system permits are generally issued for campgrounds, schools, and commercial establishments, that are not single-family homes. Local public health departments oversee the location, design, construction, installation, alteration, repair, and operation of single-family home septic systems with design flows of less than 2,000 GPD. The Department recommends that subsurface sewage disposal system owners follow the guidelines in this advisory.
