Waste Water Division

APWA Four Color-Round


The Waste Water Division maintains both the collection systems and the treatment plant. The collection systems consist of lift stations, force mains, and gravity lines. The treatment plant is permitted by the Texas Commission of Environmental Quality (TCEQ) to treat up to three million gallons a day.

Dispose of Cooking Oils and Grease Responsibly

Did you know when you pour your cooking grease down the drain it collects in your sewer lines forming a solid “grease log”? This “grease log” obstructs the sewer lines, which can cause the sewer to back up into homes and places of business. Find out how to reduce fats, oils, and grease in your home.


How are the charges for sewer determined? 

Sewer charges are based on the average of readings from December, January, and February. Using as little water as possible during these months will help to keep your bill lower all year long. For further questions, please call utility billing at 214-975-0480. View a list of the current rates

What is a sanitary sewer clean-out?

A sanitary sewer clean-out is a plumbing access point to the structure's main sanitary sewer drain piping to allow cleaning entry point when a stoppage occurs.

Where are sanitary sewer clean-outs?

Clean-outs for your home service lines are located in front of your home, near your house, and look like two white pipes sticking up out of the ground. 

What should I do if my sewer is backing up? 

If it is during normal business hours, immediately contact the Waste Water Division at 972-377-5556. For after-hours, please call 214-975-0400. 

Can sewer gas enter my home from city sewer pipes?

Sewer gas can enter a building when the water located in a trap in the building evaporates. All fixtures that are connected to the sewer system must have traps on them. The water normally retained in the trap forms a barrier, keeping the gases from migrating from the sewer lines into the building.
