My septic system has "higher level treatment", what does that mean?

Onsite Wastewater Treatment Systems (OWTS) that utilize higher level treatment are typically required to do so because of setback reductions to wells or watercourses, to shrink the size of system footprint, or because it is a requirement of an property owners association. Higher level treatment systems may not be changed or removed unless they receive permitted approval to do so. Systems that utilize higher level treatment must maintain an operation and maintenance contract for the life of the system and an Operating Permit for the life of the system. 

For more information on Operating Permits and higher level treatment systems you can visit the Operating Permit web page or contact
