What is an individual Sewage Disposal System (ISDS)?
An individual Sewage Disposal System (ISDS) is a privately owned and maintained sewage disposal system. They are commonly referred to as septic systems or onsite wastewater systems. All ISDS have two basic components, a two-compartment septic tank and disposal field. The septic tank serves to separate and store solid material and the disposal field allows wastewater to percolate into the ground.
