Water bills are generally high due to increased water usage, but it may also be the result of a water leak. Contact Regional Water at 281-897-9100 to schedule a no charge “check for leak” service call. Customer can also check faucets, toilets, water softener systems and irrigation systems for leaks. A slow drip faucet can waste 15 to 20 gallons of water a day. A leaking toilet can waste up to 100 gallons of water a day. Outdoor watering/irrigation systems can account for 50% or more of your water use during the summer months. Check irrigation system and timer settings to eliminate water waste.
