Sewer Line Experts for San Mateo
San Mateo's sewer infrastructure varies dramatically by neighborhood — San Mateo Park has some of the oldest laterals in the county (1920s-40s clay), while Bay Meadows has modern PVC from the 2000s. The city's east-west topography means hillside western properties flow to flatland eastern collectors.
Trenchless technology is particularly valuable in San Mateo Park and Baywood where mature landscaping and established gardens make traditional excavation devastating and expensive.
