Private Water Systems

Program Services
The Logan County Health District examines and permits private water systems in Logan County.

A private water system is a system that serves less than 25 people per day, or serves 25 or more people less than 60 days per year, or have less than 15 service connections.

  • A church with its own water well may serve 500 people, but maybe only 52 times per year. This is a private water system.
  • A campground with a water well system that serves about 100 people during peak times, but only 20 days of the year. This is a private water system unless there are 15 or more campsite water connections (service connections).
  • A restaurant, that does not serve water to its patrons and does not provide water for human consumption. Such restaurants only use water for hand washing, restroom, washing dishes, ice machines and coffee machines. The washing of food preparation utensils alone does not qualify a system as a public water system.
Homeowners can download their well logs from the Ohio Department of Natural Resources website.

Well Disinfection
Well disinfection can eliminate or reduce many different kinds harmful bacteria and viruses as well as harmless bacteria which can cause unpleasant taste and odors. However, disinfection will not correct water problems caused by chemical contamination from nitrate, fuels, pesticides, or other substances. Well disinfection should be performed under the following circumstances:
  • When coliform bacteria are present in the water
  • After flooding of the well
  • After plumbing installation, e.g. softeners, sinks, filters
  • After casing or pump repairs - submersible types or other
  • When water taste or odor changes, e.g. from iron or sulfur reducing bacteria
  • As part of annual maintenance
  • During start up of seasonal wells
Well Disinfection Instructions (PDF) are available. Also, the article Water Quality (PDF) provides a great checklist for well owners.
