Water and Sewer Rates

The Crystal Lake Public Works Department takes pride in the quality of drinking water and sewer services that we are able to provide to residents. The impeccable quality and the affordable user rates make these services a bargain for City residents. To view the current Water and Sewer Rates Ordinance please click here.

WaterSense Appliances

The City of Crystal Lake is 100% dependant on groundwater as its water source.  This finite resource must be conserved and protected for the next generation.  By installing water efficient fixtures and reducing indoor water use, our residents could generate a notable decline in water demand. For example, if all outdated toilets in Crystal Lake were updated to water efficient toilets, the demand to the water system may be reduced by up to 90,000 gallons of water per day.
