Private On-site Water Supply System
All seasonal or year-round residential structures require an approved water supply prior to construction. The first step in the process is to submit an application with payment and schedule a site evaluation. Once approved, a permit is issued and a Well Driller, registered with the State of Michigan, can drill your new or replacement well. The owner will receive a packet in the mail containing the permit and water sample bottles. The owner is responsible for taking and sending in the water samples to the Laboratory for Coliform bacteria and Nitrates/Nitrites. The well driller will submit a Well and Pump Record either on Wellogic or to the health department for approval.
Community and Non-community Water Supplies
The Community Water Supply Program oversees the primary EPA program that sets forth minimum standards for safe drinking water as well as administering the requirements of Michigan's Safe Drinking Water Act. The program's primary function is regulatory oversight of approximately 1,425 community public water supplies in Michigan.
A Non-community Water Supply is a water system that provides water for drinking or potable purposes to 25 or more persons at least 60 days per year or has 15 or more service connections.
Michigan is home to nearly 10,000 non-community water supply systems, which includes schools, restaurants, motels, campgrounds, and churches. The Michigan Safe Drinking Water Act (Act 399), enacted in 1976, enabled the Michigan Department of Environmental Quality (DEQ) to maintain primacy (state authority) over the drinking water program in our state. The DEQ contracts with local health departments to maintain a non-community water supply program in each county. Non-community water supply staff at DEQ supports the local health departments through training, technical support, and program evaluation.
Types of Community and Non-community Water Supplies are:
