Local septic systems for Oroville
Oroville is the Butte County seat, set where the valley floor meets the Sierra foothills along the Feather River below the tallest dam in the United States. BC Brown General Engineering has provided septic work for Oroville and the surrounding Butte County area since 1999, with the equipment and the track record to back it up.
Foothill ground around Oroville usually percs well, but rock and slope shape the design. We run the perc and soil-profile tests, lay out the tank and leach field to fit the grade and required setbacks, and install a system built for the lot.
Oroville is a short run southeast 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.
