Water Rates

Water rates are structured to balance reasonable rates with the need to budget appropriately for the purchase of water and debt service payments to cover system improvements, both current and future. By reviewing rates annually, we are able to ensure that both priorities are observed. The rate structure is designed to encourage conservation by charging more per gallon to customers who use higher volumes of water.
