Septic Systems done right in Chico
BC Brown General Engineering has handled septic work across Chico and Butte County since 1999. Chico is the largest city in Butte County and BC Brown's home base, the commercial hub of the northern Sacramento Valley anchored by Chico State and Bidwell Park, and that local knowledge shapes how we approach every job here.
On the heavy valley soils around Chico, percolation is the whole design question. Tight clay drains slowly, so the leach field has to be sized right, and where soils are poor we install engineered or pressure-distribution systems that meet code instead of failing in a few years.
Chico is just north of our Durham yard, so we mobilize crews and equipment there regularly and keep our response times short. We pull the septic permits through the Butte County Environmental Health Division, handle the perc testing and design coordination, and see the job through final inspection so you are not chasing paperwork.
