Septic Systems in Cohasset, Butte County
When Cohasset property owners need septic work done right, BC Brown General Engineering is the local call. Cohasset is a rural ridge community north of Chico, reached by a long winding road through the foothills. We have worked this ground since 1999 and know what it takes.
Foothill septic in Cohasset works around rock and slope: finding usable leach area, benching tanks in safely, and keeping effluent moving where gravity and the county both agree.
At Cohasset, septic is the only option, there is no municipal sewer, and shallow soil over rock plus deep frost drive the design. We test the soil, design around setbacks from wells and waterways, and install systems that hold up to mountain conditions.
Cohasset is up the ridge north of Chico, 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.
