Summer Water Conservation

Water resources are vital for our community. Andover residents and businesses use a significant amount of water for lawn irrigation during peak water demand months: mid-June through mid-September. This increase in use reflects 6,300 gallons per minute that is applied primarily to lawns by irrigation systems and sprinklers. We ask that you take steps to reduce water usage. By consuming less water, you help to preserve our resources. More efficient water use begins with individuals. 

The Water Division continuously monitors the water demand and levels in our storage tanks and reservoirs to ensure we provide high quality water and fire protection. Continue reading below for current water restrictions and frequently asked questions, water savings tips, resources and more.  


Summer 2021

Water Restriction Status: There are no mandatory restrictions at this time. 

Lawn care and gardening tips:


  • Mulch around trees and plants to promote plant growth and reduce weeds.
  • Keep your grass 3 inches tall. Taller grass has deeper, healthier roots. Watering deeply and less often is generally best, to moisten the whole root zone.
  • Water during the coolest part of the day. Early morning is better than dusk since it helps to prevent fungus, and allows water to seep through the thatch later, before evaporation occurs during the day.
  • Avoid lawn watering on windy days.
  • Water plants, not pavement.
  • Mow your lawn with a sharp blade. Mower blades should be sharpened after every 10 hours of use.
  • In June and July, lawns need about 1 inch of water per week, spread over 2 or 3 waterings, to stay green. They need only ½ to ¾ inch per week the rest of the summer. If there has been an inch or rainfall during the week, you do not need to water at all.
  • Overwatering can actually weaken your lawn by promoting shallow roots that are less tolerant to drought and more likely to be damaged by insects.
  • Utilize rain barrels to reuse water on a sunny day.
  • Do the Walk Test to determine when your lawn needs water:
    o The Walk Test: Does your grass stand up straight after being walked on? If not, your lawn is thirsty. Walk across your lawn and back. If you can still see your footprints after a few minutes, your grass needs water.
  • Maintain irrigation systems to prevent leaks and waste. Learn how to find and fix leaks on US EPA’s website at https://www.epa.gov/watersense/fix-leak-week .

Water use facts:


  • Turning off the tap while brushing teeth can save 8 gallons of water per day.
  • Letting the faucet run for 5 minutes while washing dishes wastes 10 gallons of water.
  • Running the dish washer only when it’s full can save the average family 320 gallons of water annually.

The kits include EPA certified WaterSense products such as: low flow shower head, dual spray faucet aerator, adjustable flow garden hose nozzle, garden hose timer, hose repair kit, and rain gauge.

  • Use aerators on your kitchen and bathroom faucets. Aerators help mix water with air as it leaves the spout, which reduces the amount of water needed for rinsing. 
  • Install water saving showerheads. Take showers instead of baths; showers use less water.
