Persons who plan to build an onsite wastewater treatment system must obtain a Construction-Installation Permit or a Water Pollution Control Facilities Permit (WPCF) before construction. Onsite systems must obtain a WPCF permit if the system:
Has a projected daily sewage flow greater than 2,500 gallons, or
Handles sewage with a greater strength than residential wastewater, or
Uses a technology identified by DEQ as warranting regulation.
Onsite wastewater treatment systems that do not require WPCF permits must still obtain Construction-Installation Permits.
