Average user

Water/sanitary sewer increase: 7.94%, about $5.89/month.

Stormwater fee increased from $9.50 to $10 per ERU.

Rate/bill item
Official FY26 context
Why searchers care
Minimum residential water/sewer user
City budget article listed monthly change from $33.34 to $35.52.
Explains small-user bill increase.
Average residential water/sewer user
City budget article listed monthly change from $74.21 to $80.10.
Explains common household increase.
Water system costs
FY26 budget includes operation of two treatment plants, modern lab, 10 elevated storage tanks, nearly 1,500 miles of water mains, and 1,260 miles of sanitary sewer mains.
Gives real reason behind rate adjustment.
Raw water
Budget included $1.7 million increase for raw water purchases from Tarrant Regional Water District.
Raw water cost affects retail rates.
Wastewater treatment
Budget included $7 million increase for wastewater treatment by Trinity River Authority.
Sewer charges are not just pipe charges; treatment costs matter.
Debt service and electricity

Useful when users ask why city services rose.
Garbage/recycling
Residential refuse charge increased from $21.80 to $22.71.
Water bills may include more than water/sewer.

Bill-reading tip: do not compare only the total. Separate water, sewer, trash/recycling, stormwater, late/past-due, and usage changes before assuming the water rate alone caused the increase.

High Bill: Find the Cause Before Calling

Portal data

Use hourly, daily, or monthly usage in Know Your H2O/app.

Toilet leak

A running toilet can waste about 200 gallons per day.

Irrigation leak

Summer sewer surprise

Average Winter Consumption: Sewer Charge Shortcut

What it is

AWC sets a maximum wastewater charge for the following October through September billing year.

How calculated

December-March water usage is reviewed; the highest month is discarded; the remaining three months are averaged.

New account

If your account is new, a city-wide average may be used until your AWC is established.

Question
Direct answer
Action
Why does winter use affect summer sewer?
Winter use estimates indoor wastewater going into the sewer system.
Fix leaks before December-March bills.
What if summer water use is above AWC?
Sewer is capped at AWC; water above AWC is not all billed as sewer.
Check water and sewer lines separately on bill.
What if monthly water use is lower than AWC?
Sewer use is billed equal to water use.
Lower use still helps.
When do reminders appear?
The city places a reminder on November bills with approximate averaging dates.
Read November bill messages carefully.
