Southwest Infrastructure INC is a licensed California contractor based in Temecula, Riverside County, holding CSLB license #1141220 under classification A — General Engineering, C31 Construction Zone Traffic Control, C34 Pipeline. The license was active and clear when this listing was compiled.
This trade handles everything between the house and the main or the tank: clearing and repairing blocked laterals, replacing collapsed clay or cast-iron sewer pipe, installing and servicing septic systems, and restoring failed leach fields.
Working in southwest Riverside County: The wildland interface runs right up against several of these communities, so defensible space and ember-resistant detailing come up regularly on exterior projects.
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 #1141220 is current, and check bond and workers’ compensation coverage, using the CSLB license lookup before signing a contract or paying a deposit.
