The house lateral and the two-way cleanout
By City Council resolution, the property owner maintains the house sewer lateral, which is the pipe between the main and the building.
For an interim period, and for a fee paid in advance, the city installs a two-way cleanout at or near the property line. From then on the city maintains the line from the cleanout to the main, and the owner keeps the section between the building and the cleanout.
Permits for sewer work
State law requires a permit before plumbing in cities of more than 5,000 people, apart from leak repairs and a short list of fixture swaps. Richardson’s permit pages name no separate sewer line permit.
When your house was built
The free sewer line age checker takes the year your house was built and lists the sewer pipe materials that fit that era. It opens on Richardson’s housing figures, so you can set your own build year against the town’s.
Not every sewer symptom is a sewer line problem. Clogs that return are covered under drain cleaning and leaks in the water supply pipes under repiping, and the cleanout section above explains who keeps which stretch of the line. The other services are on the homepage.
