New Hampshire 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.

By following the voluntary schedule for sprinkler irrigation from April 1 through October 31, you can help maintain adequate water pressure and supply for you and your community while also being a steward of the environment.

Best practices for lawn watering

We recommend that customers water their lawns only two times per week. The optimum time to run sprinklers is between sunrise and 9 a.m., and one inch of water per week is sufficient to keep grass green.

Follow the twice-weekly sprinkler irrigation schedule so no adjustments are needed if/when water use restrictions again become necessary.

See best practices below:

  • Please avoid wasting water by sprinkling impermeable surfaces such as sidewalks and driveways.
  • No watering is necessary if it has rained within the last 48 hours. Pay attention the weather forecast and postpone watering if rain is forecast within the next 24 hours.
  • Hand watering is strongly encouraged for gardens, flowers and other ornamentals because it is a much more efficient use of water.
