Frequently asked questions

  • Public Act 165 was signed into law on September 16, 1993, and took immediate effect. The bill amended Michigan's Safe Drinking Water Act, 1976 PA 399, as amended (Act 399).

  • There are approximately 10,500 community and noncommunity public water supplies serving an estimated 50 million visitors and residents each year. Community public water supplies are those serving cities, towns, villages, mobile home parks, apartments, etc. with at least 15 service connections or 25 or more year-round residents. Noncommunity public water supplies include facilities such as schools, campgrounds, restaurants, businesses, parks, motels, highway rest stops, etc. with their own well, serving an average of 25 or more persons per day, at least 60 days per year.

  • The fees for community water supplies are based on population served and range from $505.66 to $169,490.52. Noncommunity fees are divided into two categories. Facilities with wells serving primarily a transient population such as campgrounds, rest stops, motels, and restaurants are classified as transient noncommunity water supplies. Their annual fee is $171.92. Nontransient noncommunity water supplies (schools and businesses) routinely serve the same 25 or more persons (students/employees) for at least six months per year. The nontransient annual fee is $728.12 per year. Requirements for nontransient water supplies are much more complex than for transient water supplies, demanding a higher level of regulatory support to attain compliance.

    Note: The annual fee does not include the costs for water sample analysis.

  • Amendments to Act 399 continue to increase inspection and sampling requirements for public water supplies. The State of Michigan maintains a primacy agreement with the United States Environmental Protection Agency. This means the State retains authority to implement the public water supply program in lieu of the federal government as long as it enacts rules that are at least as stringent as the federal rules. The public water supply program includes periodic inspection of water supplies, monitoring the quality of drinking water served to the public, certification of laboratories for drinking water analysis, maintenance of a state drinking water laboratory, certification of water treatment plant operators, technical consultation, permitting and construction plan review, and training. The fees are required to enable the State to implement these regulations for public water supplies.

  • If information is incorrect, you should correct it, and return the corrected invoice with the proper payment. If the error involves a change in the invoice amount, the information necessary to recalculate the fee is provided. A written explanation for the correction must be provided, signed by an authorized representative, and submitted with the appropriate payment. Always retain a copy of the invoice for your records.

  • Act 399 contains penalties for late payment (after November 30 of each year) calculated as 9 percent per annum for community water supplies and $25.00 per month or portion thereof for noncommunity water supplies. The Michigan Department of Treasury collects all penalties.
