Average Monthly Water Bill in the U.S. by State, City, Usage and Household Size
The average water bill in the United States is not one fixed number. A small apartment in a low-rate city may pay under $30 a month for water, while a family home with lawn irrigation, high summer use, tiered rates, sewer charges and local fixed fees can pay well over $100.
This 2026 guide explains the average U.S. water bill, state-by-state monthly water cost estimates, city cost-per-gallon examples, household-size math, how sewer changes the total bill, and what to check if your bill looks higher than normal.
Water-only national estimate
$43/moA broad 2026 household estimate for water-only service, with lower and higher markets varying widely.
Family of four estimate
$78/moA practical family-of-four benchmark based on about 100 gallons per person per day.
Common monthly range
$19–$123Low-use and low-rate homes may be much lower, while high-rate or high-use states and cities can be much higher.
Quick answer: what is a normal water bill in 2026?
A normal U.S. water bill often falls between about $40 and $80 per month for many households, but the real number depends on your state, city, household size, irrigation, rate structure and whether sewer is included. Water-only bills are usually lower than combined water-and-sewer bills.
Average Monthly Water Bill by State in 2026

Average Water Cost by City: Why Local Rates Matter More Than State Averages
Water is priced locally. Even inside the same state, one city may use a flat fee, another may use increasing block rates, and another may charge separate stormwater, sewer or drought surcharges.
| City example | Region | Example cost per gallon | What it tells you |
|---|---|---|---|
| Pawtucket, RI | Northeast | $0.0053–$0.0057 | Local utility rates can be several times higher than low-cost cities. |
| New York, NY | Northeast | $0.0065 | Large city systems may use combined water/sewer billing rules. |
| Dothan, AL | Southeast | $0.0028–$0.0047 | Some smaller markets may be lower per gallon. |
| Orlando, FL | Southeast | $0.0008–$0.0135 | Tiered use can create a very wide range. |
| Atlanta, GA | Southeast | $0.0034–$0.0082 | Usage level and tier can change cost. |
| South Bend, IN | Midwest | $0.0036 | Midwest rates can be lower but fixed fees still matter. |
| Chicago, IL | Midwest | $0.0049 | Large systems may still be moderate water-only, but sewer adds cost. |
| Corvallis, OR | Northwest | $0.0033–$0.0060 | Rainy regions can still have high infrastructure costs. |
| Seattle, WA | Northwest | $0.0077–$0.0158 | High local rates can push bills above state averages. |
| Roswell, NM | Southwest | $0.0083–$0.0092 | Dry-region water and conservation costs can raise rates. |
| San Diego, CA | Southwest/West | $0.0098–$0.0139 | Imported water, drought planning and tiers can make bills higher. |
City-cost lesson
A city with a lower per-gallon water rate can still have a higher monthly bill if it has high fixed meter fees, sewer charges, stormwater fees, trash collection or minimum charges. Always compare the full bill, not only the water rate.
Average Water Bill Calculator for 2026
Use this simple calculator to estimate water-only cost from daily household use. Add your sewer, stormwater, trash or fixed fees separately if your local bill includes them.
Estimate monthly water cost
$54.31 estimated water-only bill
Example: 4 people × 82 gallons/day × 30 days = 9,840 gallons. At $4.30 per 1,000 gallons + $12.00 fixed fee.
Average Water Bill by Household Size
Household size matters because water use rises with showers, toilet flushing, laundry, dishes and outdoor needs. EPA says average use is around 82 gallons per person per day, but homes with outdoor irrigation, pools or leaks can use much more.
| Household size | Estimated monthly use at 82 gal/person/day | Water-only cost at $4.30/1,000 gal + $12 base | Budget note |
|---|---|---|---|
| 1 person | 2,460 gallons | $22.58 | Small apartment or conservative use may be near low end. |
| 2 people | 4,920 gallons | $33.16 | Sewer and fixed fees can make the full bill higher. |
| 3 people | 7,380 gallons | $43.73 | Usage starts to show clearly in tiered systems. |
| 4 people | 9,840 gallons | $54.31 | A family of four can be around $78/month in some benchmarks. |
| 5 people | 12,300 gallons | $64.89 | Outdoor watering can quickly push this higher. |
| 6 people | 14,760 gallons | $75.47 | Tiered pricing may raise marginal gallons. |
Why Water Bills Vary So Much by State and City
Water is local. The same 8,000 gallons can cost very different amounts in two cities because each utility has its own source water, treatment plant, pipe age, energy cost, debt, conservation rules and rate structure.
Rate structure
Flat, uniform, increasing block, seasonal, drought and water-budget rates can all change your monthly cost.
Fixed monthly fees
Base charges help pay for pipes, treatment plants, storage tanks, billing staff, loans and infrastructure before usage is added.
Outdoor water use
Summer lawn watering, pool filling, gardens and irrigation can create large seasonal spikes even when rates stay the same.
Sewer charges
Combined water-and-sewer bills can be much higher because wastewater treatment is often billed separately from water delivery.
Leaks
Running toilets, irrigation leaks and hidden service-line leaks can make one month look completely abnormal.
Local infrastructure
Old pipes, new treatment requirements, water imports and debt service can raise rates in certain cities.
If Your Water Bill Is Higher Than the Average
A bill above the state average is not automatically wrong. First compare usage, rate class, fixed fees, seasonal use and sewer charges. Then look for leaks or payment issues.
Compare gallons, not only dollars
Look for gallons, CCF, HCF or thousand gallons. If usage increased, the bill may be responding to actual water use.
Check whether sewer is included
Many “water bills” are actually water + sewer + stormwater + trash bills. Compare the water-only line separately from the total amount due.
Run a leak check
Turn off all water inside and outside. Watch your meter or usage portal. If usage continues, check toilets, irrigation, faucets, water softeners and service lines.
Check seasonal or drought rates
Some utilities charge more during high-demand periods or drought stages. Summer bills can rise even if your base rate looks normal.
Call with a specific question
Say: “My usage changed from ___ to ___ gallons, and my bill changed from $___ to $___. Can you explain the rate tier, fixed charges and sewer line?”
Find Your Local Water Utility Rates by City

A broad U.S. household water-only estimate is around $43 per month, while a family-of-four benchmark can be around $78 per month. Actual bills vary by state, city, household size, outdoor use, fixed fees and whether sewer is included.
Which state has the highest average water bill?
Using the 2026 state estimate table, West Virginia is listed highest at about $123 per month for water-only service. Local city rates may still differ.
Which state has the lowest average water bill?
Using the 2026 state estimate table, North Carolina is listed lowest at about $21 per month for water-only service. Your city or county utility may be higher depending on sewer and fees.
How much water does an average person use per day?
EPA WaterSense says average use is around 82 gallons per person per day, but it varies by climate, household habits, irrigation, fixtures and leaks.
What does CCF or HCF mean on a water bill?
CCF and HCF usually mean 100 cubic feet of water. One CCF or HCF equals 748 gallons.
Why is my water bill higher than the state average?
Your bill may be higher because of more people in the home, lawn watering, pools, leaks, tiered pricing, drought surcharges, fixed fees, sewer charges, stormwater, trash, prior balance or local infrastructure costs.
Does the average water bill include sewer?
Not always. Some published averages are water-only, while many real monthly utility bills include water, sewer, stormwater, trash and other fees. Check your bill line by line.
How do I estimate my monthly water bill?
Multiply people in the home by gallons per person per day, then multiply by 30 days. Divide by 1,000 if your rate is per 1,000 gallons, multiply by your local water rate, and add fixed monthly fees.
Why does my summer water bill increase?
Summer bills often rise because of lawn watering, pools, gardening, car washing, drought rules and seasonal rates. Outdoor use can add thousands of gallons in one billing cycle.
Can a leak make my water bill much higher?
Yes. A running toilet, irrigation leak, broken pipe, stuck softener or hidden service-line leak can waste thousands of gallons before the next bill arrives.
How do I compare city water costs?
Compare the usage unit, per-gallon or per-CCF rate, base fee, tiered pricing, sewer charge, stormwater fee, billing period and household usage. Do not compare only the total amount due.
Where can I find my exact local water rate?
Search your city, county, water authority or utility district website for “water rates,” “utility rates,” or “water and sewer rate schedule.” Your bill may also list the official customer portal.
