If you have a high water bill and do not know why, call the Marion Water Department. A representative will come to your home to assist in determining the cause. In most cases, high water usage is caused by a leaking faucet, malfunctioning water softener, furnace humidifier, ice maker, or toilet. We recommend that you make these repairs to reduce the wasted consumption on your monthly bill. If you need assistance, please call 319-743-6310.
