CSG is a family-run business established in 1934 with a local depot in Aylesford. We’re specialists in off-mains waste services and carry out sewage clearances at hundreds of properties every day. We have over 80 years of experience and knowledge, specialising in septic tank, cesspit, sewage treatment plant and grease trap collections, maintenance and repairs. •Using a modern fleet of vehicles that range in size means we’re prepared for any situation that may arise; some of our vehicles have jetters to enable us to unblock drains as necessary.
