Site evaluations determine the soil's ability to accept sewage effluent by determining soil type, seasonal high water table, lot size, and topography.
A construction permit is issued based on soil type, other limiting factors, the size of the structure, and potential water usage. It includes the size of the septic tank(s), secondary disposal system(s), specific location if necessary, and any fill required to overcome soil limitations. Once a sewage system is installed but before it is covered, a final inspection is conducted to ensure the system is installed in compliance with the permit. A diagram of the system size and location is provided.
Evaluations of existing systems are conducted to determine the condition of the sewage system, usually at the request of a lending institution or home buyer. Consultations are provided for on-site sewage disposal systems during all phases of the process.
The Allegan County Water and Sewage Regulations govern sewage disposal systems for one and two-family residential dwellings. Sewage systems for commercial establishments with flows up to 10,000 gallons per day are covered by the Michigan Criteria for Subsurface Sewage Disposal. Sizing is covered by the Michigan Department of Environmental Quality. Construction permits issued for commercial systems are issued based on the requirements of the Michigan Criteria for Subsurface Sewage Disposal.
