RCI Septic Service is now a proud member of the Greater Derry Londonderry Chamber of Commerce. Being a member of the Chamber has great advantages for small businesses like ourselves. The Chamber of Commerce is often called by local residents for referrals. In particular new residents coming into the town need a full “bag” of resources. Resources like, who to call for septic tank cleaning or problems with septic system (foul odor inside or outside the house; standing water on the leachfield, slow draining toilets or drains). As a member of the GDLC, they will refer RCI Septic Service (as well as any other like businesses who are members).
