    100,000-Gallon Water Storage Tanks Ready for Onsite Delivery and Installation

    Engineered 100,000-gallon water storage tanks are ready for commercial applications. The three-ring XLE 50/03 Pioneer Water Tank model increases capacity with tank wall height instead of a wider diameter. The higher tank wall height is accomplished with thickening the first and second tank wall rings for durable strength. The roof truss system for this tank model is also strengthened along with having more roof trusses as compared to the other standard tank models.
