What Is the Average Water Bill? How to Compare Yours Fairly

The honest answer: there is no single average bill

People search for the “average water bill” to check whether theirs is normal. It is a fair question, but a national dollar average can mislead you. Water prices are set by thousands of local utilities. Some bills include only drinking water. Others add sewer, stormwater, and trash. Billing can be monthly, every two months, or quarterly.

The most useful approach is to compare in two steps. First, check whether your water use is typical for your household size. Then check what your own utility charges for that amount of water. This guide gives you national reference points for both, with their limits.

What the national figures say

EPA’s WaterSense program says the average family spends more than $1,000 a year on water costs. EPA does not break that figure down on the page, so treat it as a broad national signal, not a benchmark for your town. It works out to a little over $80 a month.

For usage, EPA gives clearer numbers. It says each American uses an average of 82 gallons of water a day at home. Outdoor use averages more than 30 percent of household use, and can reach 60 percent in dry regions.

• About 82 gallons per person per day at home (EPA)
• About 10,000 gallons in 30 days for a family of four (EPA)
• More than $1,000 a year in water costs for the average family (EPA)

Step 1: Compare your usage, not your total

Find the usage on your bill and the number of days it covers. Convert it to gallons per day. If your bill uses CCF (hundred cubic feet), multiply by 748 to get gallons. If it uses “1,000 gallons,” multiply by 1,000.

Here is an illustration with made-up numbers. A bill shows 9 CCF over 30 days. That is 9 × 748 = 6,732 gallons, or about 224 gallons a day. For a household of three, that is about 75 gallons per person per day, close to EPA’s 82-gallon average. If the same household used 600 gallons a day in winter, that would be a reason to look for a leak.

EPA offers one more rule of thumb in its leak guidance. If a family of four uses more than 12,000 gallons a month in a cold month like January or February, there could be serious leaks. Winter is a good test month because there is little outdoor watering.

Step 2: Compare your price with your own utility, not a national number

Once you know your usage is normal, look at what you pay per unit. The bill comparison calculator on this site turns a bill into cost per 1,000 gallons. It uses the whole bill, so the result includes fixed charges and any sewer or other fees. That makes it good for comparing your own bills over time, not for comparing official rates.

For a fair outside comparison, look up your utility’s published rate schedule. It shows the fixed monthly charge and the price per unit in each tier. Then compare with a neighboring utility’s schedule at the same usage. Even nearby towns can charge very different prices because of water sources, system age, debt, and how costs are split between fixed and usage charges.

Why bills vary so much from place to place

Local factors drive most of the difference. A city that buys treated water from a regional supplier pays different costs than one with its own wells. Older systems may be replacing pipes. Places with sewer upgrades or stormwater programs often have higher combined bills.

Rate design matters too. EPA describes several common structures. A uniform rate charges the same price for every unit. Increasing block rates charge more per unit as you use more. Seasonal rates charge more in summer. Water budget rates give each household an allowance and charge more above it. The same 10,000 gallons can cost very different amounts under each.

Water prices are rising

Federal price data show water costs rising faster than prices overall. In the Bureau of Labor Statistics consumer price index for September 2026, the “water and sewerage maintenance” category was up 4.7 percent from a year earlier. All items were up 3.7 percent over the same period.

That is a national figure. Your utility may have raised rates more, less, or not at all this year. Check the effective date on your utility’s rate schedule or the rate notices that often come with a bill.

About the surveys you may see quoted

You may see older city rankings online. Circle of Blue’s well-known price survey covered 30 large U.S. cities, and the most recent edition we could find is from 2019. It covered drinking water only. The survey itself notes that it does not consider sewer or stormwater fees, which in many cities are higher than water rates.

The American Water Works Association and Raftelis run a rate survey of 500 water and wastewater utilities. It is a paid subscription product, so its detailed figures are not public. When you see an “average bill” number online, check its year, which charges it includes, and how much water it assumes.

A quick self-check

Use this checklist to decide whether your bill needs a closer look.

• Is daily use per person roughly in line with about 82 gallons? If it is far higher in a cold month, test for leaks.
• Did usage change compared with the same month last year?
• Did the bill cover more days than usual?
• Did your utility change rates recently?
• Does the total include sewer, stormwater, or trash charges?
• Is there a past-due balance or late fee included?
