Outdoor Conservation

In Northeastern Illinois, the average person uses 109 gallons of water each day and In about 31% of this water is used for outdoor purposes. And, 80 – 90% of the outdoor component of residential water use goes to lawn care. Small steps in outdoor water use can save a lot of water.

  • •A typical Illinois lawn needs about 1- 1 ½ inches of water each week, including rain according to
  • In Illinois, cool season grasses can go dormant during hot, dry weather without watering and recover when growing conditions improve in the late summer or early autumn.
  • Overwatering causes runoff, wastes water, and carries fertilizers and other chemicals into the sewer system.
  • Rain gauges measure how much rain was received at a specific location over a designated period of time. Keep track of weekly rainfall totals to determine whether your lawn needs additional water.

Outdoor water efficiency is especially important during the hot summer months when as much as 50% of home water consumption is for watering lawns and gardens.

You can increase efficiency by using a rain barrel. A rain barrel is a water tank which is used to collect and store rainwater runoff, typically from rooftops. Instead of running down driveways and sidewalks to sewers, rainwater falls into a rain barrel where it can be stored for use in gardens and for house plants. They are a simple, efficient, low-cost method for homeowners to conserve water.
