Proper design and maintenance of drinking water wells is necessary for the protection of public health. The Private Well Guidelines:
- Explain what private water supplies (private wells) are
- Assist well drillers with construction standards
- Provide useful information for well owners
The Guidelines
A private water supply provides water for human consumption and consists of a system that has less than 15 service connections and either:
- serves less than 25 individuals, or
- serves an average of 25 or more individuals daily for less than 60 days of the year.
In the Commonwealth of Massachusetts, over 500,000 people rely on private wells to provide drinking water because a public water supply is not available to them.
Local boards of health are responsible for regulating private wells. The Private Well Guidelines assist boards of health and well drillers by attempting to introduce some consistency regarding construction standards from town to town. The Guidelines also provide information useful to well owners, developers, and interested local officials.
