WaterWise Water Conservation Program

Did You Know?

  • 50% of household water is used on lawns and landscapes.

  • The best and most efficient time of day to water your lawn is before 8 am and after 5 pm.

  • Unless you own a WaterSense certified smart irrigation controller, your irrigation schedule should be adjusted monthly.

  • You can save over 300 gallons in one month by running your dishwasher only when it is full.

  • Treatment plants and potable water distribution systems must be built 3-4 times larger due to the increased demand of summer lawn irrigation.

  • Aquifers are rocks or deposits located underground that hold water in cracks or spaces between layers of sand or gravel.

  • The majority of Chanhassen's water supply comes from the Prairie du Chien-Jordan aquifer.


The WaterWise Program helps residents, business owners, and organizations reduce water usage throughout Chanhassen. Water use has continued to rise each year within the city, partly due to increased population and partly due to increased demand in general. The highest use occurs in the summer when thousands of irrigation systems are pumping drinking water to spray on lawns. This puts unneeded stress on the aquifers we draw from and costs taxpayers as extra wells and systems are built to meet the demand for water during peak times.

The WaterWise Program offers educational opportunities and incentives to reduce water usage at home and at work. Saving water at home saves you money. Check out these links on ways to use water more efficiently.

The City is also offering rebates on WaterSense certified toilets and irrigation controllers as well as Energy Star clothes washers and dishwashers. You can find out program details with the link below and find products that meet the requirements.

July is Smart Irrigation Month

July is declared 'Smart Irrigation Month.' Sponsored by the Irrigation Association, Smart Irrigation Month is a national campaign to increase awareness about simple practices and innovative technologies homeowners and businesses can use to sustain healthy lawns and landscapes while using water resources more efficiently.

July is a peak month for water use. For example, the City of Chanhassen supplies an average of 4 million gallons of water per day during the winter. In the summer, daily water use goes up to as much as 16 million gallons. Lawn irrigation accounts for most of the summertime increase, making July a good month to consider smart irrigation practices and technologies that conserve water.

Reducing water use can help homeowners and businesses save money on their utility bills. It also contributes to reducing the need for costly public spending on new infrastructure to store and convey water and protects our communities' water supplies for the future.
