Type II and Type III Non-community Water Supplies
WELLS SERVING BUSINESSES AND INSTITUTIONS
Any well that serves a business or institution is considered a public water supply in Michigan. Public water supplies are regulated under authority of Michigan Safe Drinking Water Act, Act 399 of the Public Acts of 1976.
Community Water Supplies
Supplies that serve municipalities, such as city or township water supply wells, are considered "community" water supplies. Community water supplies also include wells that serve 14 or greater residential living units. Community water supplies are regulated by the Michigan Department of Environmental Quality (MDEQ). If you wish to permit a community water supply well you must contact the MDEQ. Community water supplies are classified as Type I supplies under Act 399.
Non-community Water Supplies
Non-community water supplies include water supplies and associated wells that serve water to the public, to employees or to members of a facility and are not "community" supplies. These supplies include those serving restaurants, schools, offices, stores, general small businesses, motels/hotels, industrial operations such as mines, pubic swimming pool facilities etc.
Non-community water supplies are divided into two main categories under Act 399 based upon the number of individuals served. Those that serve 25 or more individuals per day for any 60 days in a year are classified as Type II non-community water supplies and those the serve fewer than 25 are classified as Type III non-community water supplies.
Your local Health Department is responsible for regulating all non-community public water supplies within their jurisdiction.

Large Quantity Withdrawal
If your proposed well has the capability to withdraw 70 gallon per minute of water from the aquifer, you must submit to the Michigan Department of Environmental Quality (MDEQ) for an assessment of the potential impact to the aquifer. Information regarding the large quantity withdrawal review process can be found at this LINK.
