Lawn Watering Ordinance
To help conserve water, we have an ordinance that covers rules for lawn watering from May 1 to September 30.
- Properties that have an odd-numbered address can water their lawns on odd-numbered days
- Properties that have an even-numbered address can water their lawns on even-numbered days
- No watering from Noon to 4:00 p.m. on any day
If you have any questions, contact the Water Department at 952-448-4335.
The Chaska Water & Sewer Department is responsible for the maintenance and operation of the City's drinking water system and sanitary sewer collection system.
