Sewer Line Maintenance
Prevention of Inflow / Infiltration
A primary effort regarding sewer line maintenance is prevention of inflow / infiltration - stormwater getting into pipes, thus increasing flows to our treatment facilities, resulting in increased costs to the City.
There are several tests Highland Village uses to examine the condition and susceptibility of its sanitary sewer system to inflow/infiltration. A few of these tests include:
Contact the City at (972) 317-2989 (after hours call (972) 317-6551). City crews will respond to check the City's sewer main to verify that the sewer main is open and sewage is flowing. If the sewer main is found to be clear, it is the responsibility of the property owner to call a licensed plumber or drain cleaning service to correct the problem.

There are several tests Highland Village uses to examine the condition and susceptibility of its sanitary sewer system to inflow/infiltration. A few of these tests include:
- Smoke Testing: This method includes blowing smoke from a smoke bomb into a specific section of the sewer pipe, and documenting where smoke exits.
- Dye Testing: Inadequate pipe connections can be detected using a fluorizine dye. If dye that is introduced into a catch basin is later observed in the sanitary sewer downstream, this may indicate that that catch basin is inadequately connected to the sanitary sewer system.
- Closed Circuit TV Inspection: TV cameras placed inside sanitary sewer lines are used to sewer conditions. This method is also helpful in estimating how much infiltration might occur from such leaks.
- Highland Village's Infrastructure Asset Management Program: Over the next year you will see utility crews identifying water, wastewater, and storm drainage assets which include sewer property line clean-outs usually located between the street and your property line.
