SD Tank manufactures self-supporting steel fire-water storage tanks and pump-house buildings at Cewice in Pomerania, offering design-and-build delivery with a stated fifteen-year tank warranty. CNBOP-PIB’s register of Krajowe Oceny Techniczne lists it as holder of CNBOP-PIB-KOT-2024/0401-1005 for extinguishing-medium reservoirs — self-supporting vertical cylindrical fire-water tanks ranging from four to several thousand cubic metres — which is the assessment Polish building law requires before such tanks may be placed on the market. The company additionally cites FM Approvals, NFPA and VdS references for its tank range.
