A Non-community Water Supply (also known as a Type 2 or Type II water supply) is a water system that provides water for drinking or potable purposes to 25 or more persons for at least 60 days per year; or, has 15 or more service connections. In Washtenaw County, many churches, restaurants, and other facilities are classified as Type 2 water supplies.
Revised Total Coliform Rule
The federal Safe Drinking Water Act (SDWA) requires that all public water systems provide an adequate supply of safe drinking water to customers and consumers. The Revised Total Coliform Rule (RTCR) sets limits for coliform bacteria in drinking water, and requires all public water systems (including Type 2 systems) to monitor for the presence of total coliform bacteria in the distribution system.
The RTCR applies to all Type II water supplies:
- Transient
- Non-transient
- Year-round
- Seasonal
View Washtenaw County Environmental Health Division's presentation "The Revised Total Coliform Rule (RTCR) for Year-Round Non-Community (Type II) Water Supply's in Washtenaw County (PDF)" to see how the revised rule impacts your facility.
