Local sewer tie-ins & underground for Oroville
BC Brown General Engineering has handled sewer work across Oroville and Butte County since 1999. 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, and that local knowledge shapes how we approach every job here.
Parts of Oroville 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.
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 coordinate the tie-in and inspection with the local sewer authority and pull any permits the connection requires.
