Outdoor Watering Restrictions

Ban on Lawn Irrigation in effect (updated 6/5/2020)

Due to the ongoing dry weather, and two of our sources currently being unavailable due to delays in maintenance activities caused by COVID-19 interruptions, we are implementing a ban on lawn irrigation effective immediately.  This includes above ground sprinklers and automated inground irrigation systems.  The establishment of new lawns is included in this ban on lawn irrigation. The remaining components of our seasonal outdoor water use restrictions remain in effect, including the limits on using water outdoors based on your address.  As a reminder, this includes other outdoor water uses including but not limited to power washing, watering gardens, car washing, and construction related activities.   If conditions warrant and we are able to restore water storage to acceptable levels, we may relax this ban. Any violations will be subject to a fine of up to $200 per incident. We thank you for your cooperation and any water conservation efforts that you observe.  Updates in the status of our outdoor water use restrictions will be communicated on our website and via Twitter @ActonWater.

Seasonal Outdoor Water Use Bylaw

As a reminder, our seasonal outdoor water use bylaw is in effect from May 1st through October 1st.  No outdoor water use is allowed on Monday.  Even numbered properties may use water outdoors on Tuesday, Thursday, and Saturday while odd numbered properties may use water outdoors on Wednesday, Friday, and Sunday.  Lawn watering is not allowed between 7 am and 7 pm on your day because a large amount of water is lost to evaporation when watering during this time.  Irrigation during windy times should be avoided because much of that water is lost to evaporation in these conditions as well.  During the growing season, lawns only require 1 inch of water, this includes any natural rainfall.  Irrigation schedules should be adjusted regularly to account for natural precipitation. 

Outdoor water use under the bylaw includes, but is not limited to, lawn and landscape irrigation (manual or automatic), filling and topping off of pools, car washing, power washing, watering of fruits and vegetables, and construction dust management.

This is also a good reminder to check your irrigation system and outdoor water systems for leaks, broken heads, and inefficient spray.  You should also familiarize yourself with the operation and shutoff for any automated irrigation systems.  Remember, it is your responsibility as a property owner to control your irrigation system in compliance with our outdoor water use bylaw.  Any property that is observed not following the seasonal outdoor water use bylaw is subject to fines up to $200 per offense.  Do not depend solely on your contractor to properly manage your controller.

Thank you for your continued assistance and cooperation in using Acton’s water resources wisely.  It takes the entire community to enable a safe, sufficient, and reliable supply of water.
