DMT – Double Wall Tanks

Inner tank dome overlaps outer tank sidewall to prevent rainwater, snow and debris from entering into the containment basin. Narrow design is ideal for space saving. Molded-in lifting lugs (large tanks only) and upper fitting flats are standard. Molded-in lower fitting flats can accommodate our sturdy optional bottom outlet.
