BC Brown General Engineering has handled sewer work across Colusa County and Colusa County since 1999. Colusa County is rice country along the Sacramento River, from the county seat at Colusa to the I-5 towns of Williams and Maxwell and the Coast Range foothills, and that local knowledge shapes how we approach every job here.
Colusa County underground work means clean trenches in heavy soil, proper pipe bedding, and compaction that keeps the patch from settling into a dip.
Parts of Colusa County are on city sewer and parts on septic. Where the main is available we trench and tie in the lateral at the correct grade, replace failed or root-choked laterals, and coordinate the connection and inspection with the local authority.
Colusa County is south down the valley, and we work it end to end, from the valley towns to the back roads. We pull the permits each job requires, from septic and grading to encroachment, and handle the agency coordination across the county.
