Residential On-Site Sewage Disposal System
District Health Department No. 4 Onsite Sewage Disposal Program is designed to assure compliance with the DHD4 Sanitary Code. The goal of the program is to effectively manage onsite wastewater disposal and treatment systems so that residents of the health district are protected against potential disease causing organisms found in wastewater and to ensure that the state’s ground and surface water resources are protected from potential contaminants.
Permit
The Sanitary code requires that property owners obtain a construction permit prior to installing or repairing an onsite sewage disposal system. An onsite sewage disposal system permit will provide the specifications and requirements for the sewage disposal system construction. The system must then be constructed in accordance the Sanitary code and with any special permit requirements.
An onsite sewage disposal system permit is valid for 2 years.
Applying for a Permit
Permit applications can be obtained at any District Health Department No. 4 office and on this website. following the submission of an application and the associated fee, a site visit will be arranged. Environmental Health staff will then conduct a site review and soil evaluation and then, if site conditions allow, issue a permit for construction of the sewage disposal system.
The site factors determining the size and location of a proposed sewage disposal system include but are not limited to:
- Soil texture and stratification (layering)
- Seasonal high water table
- Topography and slope
- Isolation to surface water and drainage areas
- Isolation to water wells
- Property line location
- The number of bedrooms in the proposed home
- Garbage grinders and/or sewage ejector pumps
* The application can be obtained from the link at the right*
Final Inspection
A final inspection of the completed system must be conducted by District Health Department No. 4 staff prior to covering/backfilling the sewage disposal system.
Final inspections will be arranged by mutual agreement with the health department and the system installer and/or property owner.
