Q: How frequently are customers billed?

Q: Why is my water bill higher than expected?
A: Higher bills often result from increased usage. New appliances, lawn watering, pool filling, or irrigation systems can significantly increase consumption. Check for leaks using our Leak Detection Guide to identify hidden water waste. Bills may also cover additional days if meter readings weren't exactly 90 days apart, or if previous bills were estimated.
Q: Can you provide tips to reduce my water bill?
A: Visit our water conservation webpage for indoor and outdoor water-saving tips. Use the Alliance for Water Efficiency's Water Calculator to identify savings opportunities throughout your home.
Q: What does an 'estimated' bill mean?
A: Bills are estimated when actual meter readings cannot be obtained due to:
- Indoor meters with limited access
- Blocked or covered meter pits
- Meter equipment malfunctions
- Reading difficulties when dials are between digits
Q: What winterization steps should I take if leaving my home for extended periods?
A: Consult with a plumber about properly winterizing your home's pipes and fixtures, especially if you have a hot-water heating system. If your heat will be off, schedule to have your water service shut off at the street. If keeping heat on, set the thermostat no lower than 55 degrees and arrange for someone to check periodically.
