Frequently Asked Questions
Usage in gallons is divided by 1,000, then multiplied by your water supply rate plus your sewer/drainage rate (both usually priced per 1,000 gallons).
About 9,000 gallons per month (roughly 300 gallons per day) for a typical US household, according to EPA estimates.
Water supply and wastewater treatment are often billed as two distinct line items, sometimes by different utilities entirely, even though both are based on the same metered water usage.
Usage significantly above the 9,000 gallon/month average often indicates a leak (running toilet, irrigation system, or pipe leak) worth investigating before it shows up on your next bill.
