First, you want to check for leaks. The “usual suspects” for leaks are toilets and in-ground irrigation systems. If no leaks are detected, then you can do some sleuthing by using your water meter. Most water meters are located in basements near the wall closest to the street. They can also be in a utility closet, mechanical room or outside in a pit in the ground. In Concord, the meters measure water use in cubic feet (CF). One cubic foot equals 7.48 gallons. You can use your meter to track water usage throughout the day or week to determine when a lot of water is being used. Are evening baths the culprit? Daily loads of laundry? Or morning lawn watering? Still baffled? CPW offers free water use audits to residential customers. Call 978-318-3250 to schedule an audit.
