Massachusetts Irrigation Schedule

Smarter watering begins with you

People across the country are putting water high on the list of things to use more efficiently, especially given the large fluctuations in the amount of rain and snow we receive. Plus, of course, the finite nature of the water supply and the essential role it plays in human, economic and environmental well-being.

Frequently Asked Questions (FAQs)

Water uses subject to Level 3 voluntary restrictions include nonessential outdoor watering activities such as:

  • irrigation of lawns via handheld watering, sprinklers, or automatic irrigation systems;
  • washing of vehicles, except in a commercial car wash or as necessary for operator safety; and
  • washing of exterior building surfaces, parking lots, driveways or sidewalks, except as necessary to apply surface treatments such as paint, preservatives, stucco, pavement, or cement

Water uses NOT subject to voluntary restrictions include essential watering activities:

  • for health or safety reasons;
  • by regulation;
  • for the production of food and fiber;
  • for the maintenance of livestock; or
  • to meet the core functions of a business (for example, irrigation by golf courses as necessary to maintain tees, greens, and limited fairway watering, or irrigation by plant nurseries as necessary to maintain stock).

  • Grass grows the deepest and healthiest roots with infrequent watering.
  • Watering two days a week is more than adequate to have a beautiful lawn. In fact, research has shown that grass thrives with about an inch of rain a week - some supplied by Mother Nature and the rest by just one watering.

Historically, when the demand for water increased in a community, the water industry considered only one solution: construct a new water supply (a well, a reservoir, or an interconnection with another community). Forward-thinking water utilities and community leaders have now come to recognize that prudent use of these precious resources is also part of the solution; in part, because spending money on new water supplies will result in higher water rates and conservation is simply better for the environment.

With this new approach, Aquarion, like many other environmentally conscious utilities, has begun implementing annual irrigation restrictions in some of the communities it serves in Connecticut and Massachusetts.

Through the Water Management Act, MassDEP regulates the amount of water that all water suppliers in Massachusetts can withdraw from the environment from its sources (e.g. wells). The irrigation schedule will help ensure that our water systems are in compliance with the WMA permit limits and requirements.

No. The restrictions do not apply to irrigation systems that are supplied with water from a private well. However, local ordinances/bylaws might apply. Please check with local officials.
The Massachusetts Department of Environmental Protection (MassDEP) regulates and closely monitors the quantity of water that water utilities withdraw from the environment.
