Water Supply Service Area Planning

By 2026, all water utilities that serve a population of 10,000 or more people will be required to develop a Water Supply Service Area Plan (see s. 281.348, Wis. Stats.).

Communities that may need to develop this plan prior to 2026 include:

  • communities located in the Great Lakes basin that plan a new or increased withdrawal over an established baseline for their current withdrawal; and
  • straddling communities or communities in a straddling county that are applying for a new or increased diversion of Lake Michigan or Lake Superior water.

The Water Supply Service Plan should be for no more than 20 years and contain the following components.

  • Information regarding current sources of water, future water demand and population projections.
  • Water supply options to meet future needs including a cost-effectiveness analysis of different options with consideration for:
    • a regional or individual water system; and
    • water conservation and efficiency alternatives.
  • An assessment of environmental and economic impacts of different water supply options.
  • An opportunity for public comment on the plan.
