A septic system or onsite wastewater treatment system (OWTS) is required for every structure with a restroom or sewer drain. Septic Permits are processed through Delta County Environmental Health - see the Health Department's Septic Systems web page for detailed information regarding septic system installation and repair.
An address must be assigned in order to apply for a Septic Permit. A minimum of two inspections are required: 1) site inspection to determine suitability to accommodate the proposed system/location; 2) final inspection to ensure the system was installed as specified in the permit. Final approval is required prior to occupancy.
Intensifying use such as creating a new parcel (subdivision) and/or a new/change of use requires proof of adequate water supply. The use of cisterns or other types of water storage vessels which require periodic refilling from an off-site source are not an acceptable domestic water supply. Cisterns continue to supply existing uses but a permanent water source must be identified to subdivide or intensify the use.
Wells are permitted by the State Engineer, Department of Natural Resources:
Colorado Division of Water Resources 1871 East Main Street Montrose, Colorado 81401 970-249-6622
Delta County has a number of purveyors that service different areas with water connections (water taps). Contact the appropriate water purveyor to check on ability and willingness to serve water for the project.
