Hydro Jetting in Pasadena, California
Short answer: Pasadena is its own city, not part of the City of Los Angeles, so LASAN does not run the sewer mains here. The city maintains the public sewer mains. The property owner is responsible for the house sewer, the private lateral. Many Pasadena homes date from the early 1900s, so old pipe and roots are common.

About Pasadena and what it means for the sewer line
- About 57% of housing units are rented.
- The Bungalow Heaven district has around 800 small homes built between 1900 and 1930.
- The Arroyo Seco runs through the city from the mountain foothills.
- Rainfall is about 20 inches a year, higher than downtown Los Angeles because of the mountains.

Sources are the Wikipedia article on Pasadena and the City of Pasadena house sewer guide. The same guide says it is not allowed to connect patio drains, downspouts, pool overflow or footing drains to the sanitary sewer, and it is illegal to open or enter a manhole. Do not lift manhole covers yourself.
Sewer line problems that can be common in Pasadena
- Original laterals in homes built in the early 1900s.
- Roots from large, mature trees.
- Wind-damaged trees that disturb lines (windstorms have toppled trees in the past).
- Multi-unit buildings with shared laterals.
- Wrongly connected drains, such as a downspout tied to the sewer.
