Advanced Underground Systems

Based in Riverside, Riverside County, Advanced Underground Systems holds California contractor license #879314, classified A (General Engineering, C42 Sanitation System). The license was active and clear when this listing was compiled.

Septic and sewer work covers septic tank installation, pumping and repair, leach field replacement, sewer lateral repair and replacement, trenchless lining and pipe bursting, and camera inspection of buried lines.

Working in the Inland Empire: Summers are long and hot and air quality is regulated by the South Coast AQMD, both of which shape material choices and how outdoor work is scheduled.

Before you hire any septic or sewer contractor: On septic, ask which county environmental health permit the work requires. Tank replacement and leach field work are permitted and inspected at the county level, and an unpermitted system is a problem at resale.

License status can change at any time. Confirm license #879314 is current, and check bond and workers’ compensation coverage, using the CSLB license lookup before signing a contract or paying a deposit.
