You may purchase an outside "deduct" meter that connects to your outside faucet. When water operators read your meter, the outside "deduct" meter will be read along with your regular house meter. The amount of water that flowed through your outside faucet will be deducted from the sewer portion of your bill. Cost of the deduct meter is $110.00. Meters are read for June and September billing only. Care must be taken to keep the meter from freezing. Store dry meter inside during cold weather.
