Frequently asked questions
- Why is my actual bill higher than the estimate?
- Most utilities charge tiered rates — the first few thousand gallons are cheap and prices rise as you use more. There are also fixed service fees, sewer charges (often equal to or higher than water) and stormwater fees.
- How can I reduce my water bill?
- Low-flow showerheads ($20–$50) can cut shower use by 40%. Fixing a leaky toilet can save 100+ gallons per day. Watering lawns at dawn reduces evaporation.
