Underground Storage Tank Removal & Roth Tank Installation

Underground Storage Tank Removal & Roth Tank Installation

CommTank provided a removal service for a 1,000-gallon underground storage tank and the installation service for two 400-gallon Roth aboveground storage tanks at this home in Concord, Ma. We removed one 55-gallon drum of sludge/oily water from the underground tank. Field technicians conducted field screening of the tank grave (four sidewalls and pit bottom) and no evidence of contamination was found. Salvageable oil from the underground tank was transferred into the new Roth tanks and the furnace was fired, tested, and left ready for operation.
