Eden Prairie may change water rates to encourage conservation and even up charges between residential and commercial users before summer lawn-sprinkling season begins.
A two-tiered charge for all users will be presented to the City Council on March 4 by Public Works Director Gene Dietz.
Lawn sprinkling boosts water demand from about 6 million gallons a day in the winter to a peak of 22 million gallons a day in the summer, Dietz said.
To control summer use, the city enforces strict sprinkling restrictions 24 hours a day, even sending officers out in the middle of the night to catch violators.
The new rates would reinforce conservation efforts but are unlikely to dramatically change habits, Dietz said.
"I am not sure we could ever charge enough to have a solid impact on water use," Dietz said.
"If you have an investment in your yard, most people are going to want to protect that investment."
Basic rates already went up from $1.55 to $1.65 per thousand gallons on Jan. 1.
