Burney Septic Services, also known as Marc's Plumbing and Septic, is family owned by Marc and Nancy Twyman. The Twyman's came to Big Valley in Lassen County to tackle a four year septic project in Eagle Lake, and Marc's Plumbing and Septic was born. Many years later the Twymans have become proud community members of the Intermountain Area and put an emphasis on supporting local business. Kind, honest, and professional, Burney Septic Services promises to serve our community and provide the best service possible.
