Sewage

All sewage shall be disposed of in a public sewerage system or in a sewage disposal system approved by the department. 1. An initial inspection shall be made of all existing onsite sewage disposal systems by the department. This inspection shall evaluate system adequacy and if no expansion of existing dwelling facilities is occurring, no expansion of the system may be required as long as the system is not failing or otherwise contaminating surface or ground water. 2. If an expansion of the dwelling facilities occurs, then evaluation of the onsite sewage disposal system shall be completed by the department. If the system is adequate, then no expansion of the system will be required. If the system is not adequate in size, then system expansion shall be required as per local regulations or, the requirements in ND Publication WP-74-1R (Septic Tank and Absorption Field Disposal Systems for the Home). Plans for expansion shall be submitted to the local jurisdiction or, the department, water supply and pollution control division, for review and approval prior to construction. 3. The department may require that the septic tank be opened to check its construction. If the department determines that pumping of the tank is necessary, the department may require this to occur. 4. If the department determines that the onsite system needs repair or a new system is required, then the system shall be repaired or replaced in accordance with local regulations, or ND Publication WP-74-1R (Septic Tank and Absorption Field Disposal Systems for the Home).
