Type II Water Supply

Inspecting Public Water Supplies

A Public Water Supply, also known as a Type II well, doesn’t have to be a community supply, but by definition, it has 15 or more service connections or serves at least 25 people on an average daily basis for at least 60 days a year. A few examples of place with Type II well are schools, restaurants, churches, campgrounds, industries, and highway rest stops with their own water supplies. These wells are further classified based on usage.

  • Nontransient: A Type II supply that serves at least 25 of the same people on an average daily basis for more than 6 months per year. This definition includes water supplies in places of employment, schools, and daycare centers.
  • Transient: A Type II supply that serves 25 or more people a day for at least 60 days of the year (or 15 or more service connections). Examples include motels, churches, golf courses, restaurants, parks, and highway rest areas.

In 1974, out of concern for the quality of water we drink, Congress passed the Safe Drinking Water Act giving the US EPA responsibility for establishing and enforcing drinking water quality standards nationwide. The Michigan Safe Drinking Water Act (Act 399) was enacted in 1976 and requires all Type II facilities to collect water samples for specific parameters, and at specific intervals. For more information, visit the Michigan Department of Environment, Great Lakes, and Energy.

As part of the Michigan Safe Drinking Water Act, HDNW conducts an inspection once every five years for Type II wells. The purpose of the surveys is to determine:

  • If your water supply system currently meets state drinking water standards
  • If your water supply system meets the minimum construction and operational standards of Act 399 and to require corrections where necessary
  • What water quality monitoring frequencies are necessary to maintain compliance with Act 399
