Charles Harris, MD-Health Officer Residential On-Site Sewage System Permit Procedure The following is a brief outline of the steps involved in obtaining a residential on-site sewage system permit. 1. Soil Profile Analysis- Contact a licensed soil scientist to perform a soil profile analysis on your property. The soil scientist will set up a time to meet you and a health department representative at your property. The soil scientist will perform a minimum of 3 soil borings in the desired location of your on-site sewage system. The information from this soil profile analysis will be sent to you and to your health department representative. A list of soil scientists can be provided upon request. 2. Minimum Requirements Letter- Your health department representative will issue a minimum requirements letter based on the soil report from the soil scientist and the number of bedrooms. As the name implies this is the minimum sized on-site sewage system required based on the soils report and number of bedrooms. The minimum requirements letter can then be used by an installer to design an appropriately sized on-site sewage system. *The issuance of a minimum requirements letter does not imply construction approval* 3. Plan Submittal - The following items need to be completed in full and submitted to the health department. A. Hamilton County On-Site Sewage System Permit Application B.

The design MUST be to scale (engineered/architectural scale). Custom scaled designs will not be reviewed b. Include all applicable items noted on the on-site sewage system design checklist D. Hamilton County Private Water Well Construction Application (if applicable) If drainage (perimeter, interceptor, or segment) is required for the system, proof of an acceptable outlet must be provided. An acceptable outlet is a stream, ditch, operating field tile, storm sewer, or other approved gravity outlet. If the drain outlets into a regulated drain, provide a copy of an approved permit from the Hamilton County Surveyor’s Office. Unregulated drains must be field verified by health department staff. 4.
