Odd/even sprinkling rules are in effect between May 15 and September 15. Sprinkling is allowed from 7 - 11 a.m. and 7 - 11 p.m. on the odd/even basis. If the last digit in your street address is odd (1, 3, 5, 7, 9) then you may sprinkle only on odd numbered calendar days. If the last digit in your address is even (2, 4, 6, 8, 0) then you are restricted to sprinkling on even numbered calendar days.
Water conservation is required for suburban communities using water from Lake Michigan. These rules apply regardless of rainfall trends and are intended to keep great lakes water sustainable to serve the millions of residents that rely upon this natural resource.
Why We Conserve Water
The city's water restrictions could be more accurately called water conservation measures. In 1967, there was a Supreme Court decision declaring that any state using Lake Michigan water was required to pass water restrictions to limit the amount of water removed from Lake Michigan.
The Illinois Department of Natural Resources instituted guidelines that state that, at a minimum, any town that uses Lake Michigan water must limit the time allowed for water sprinkling between May 15 and September 15. That is why watering restrictions are imposed 7 - 11 a.m. and 7 - 11 p.m. on odd/even days according to your address.
There are more stringent restrictions if drought conditions occur or the Oak Lawn distribution center has mechanical problems. The Public Works Department will continue to notify residents if and when any of these situations occur. We are extremely lucky to have such a bountiful natural resource at our disposal but Lake Michigan is not an endless supply. Please help conserve our natural resources.
What Can You Do to Save Water?
- Check inside faucets for leaks. Even a faucet with a small drip can waste a lot of water.
- Keep showers to five minutes or less in length.
- Turn off the water while brushing your teeth or washing your hands.
- Keep a pitcher of water in the refrigerator. Then you won't have to run tap water to cool it.
- Use dishwashers and clothes washers for full loads only.
- Use a broom to sweep your driveway, garage or sidewalk instead of using water.
- Use a bucket of water to wash your bike or car. Rinse it quickly with the hose.
- Be careful to water the lawn, not the sidewalk or street.
- Water your lawn at night or in the early morning to avoid evaporation.
- Check outside hoses, faucets and automatic sprinklers for leaks.
- Use water only when you need it. Always turn it off when you are finished.
- Install and maintain a rain barrel.
