Engineered water storage tanks Pioneer


The tank body of the XLE engineered Pioneer Water Tanks system is Grade 300MPa (44,000psi) steel sheets, profiled and fabricated according to the Pioneer Water Tanks V-lock® wall panel design. The tank wall sheets are bolted horizontally to each other and vertically to column supports. Nominal sheet dimensions are 2.2m (7.2ft) x 1.1m (3.6ft).


Wall panel sheets are pre-curved for each tank size to achieve the required circumference. Tank walls are comprised of two stacked rings. An overflow outlet is placed in one upper wall panel to account for design seismic sloshing effects. The overflow outlet height varies by tank size.

65,000 gallon water tank roof structure


The dome roof system of the XLE engineered Pioneer Water Tanks system is BlueScope Zincalume® Steel sheets fastened to the SHS roof structure and to the top flange of panel walls. XLE water tanks have a 0.42mm thick Grade 550MPA (79,800psi) roofing sheets.


The roof supporting steelwork is galvanized, welded Vierendeel trusses with Square Hollow Section (SHS) chords and web members. SHS members are Grade 350MPA (51,000psi) steel. The roof trusses are attached to the top wall panel flange with a swivel foot and bolt assembly.

    Pioneer Water Tanks Foundations

    The foundation for Pioneer Water Tanks depends on the location and application of the water storage project. Pioneer Water Tanks may have the option to sit on a clean sand pad base or may be required to be anchored to a concrete ring beam depending on the local authority.

    This short video shows a concrete ring beam being installed for a 51,785-Gallon Pioneer Water Tank in Nothern California.

    Concrete ring beam outline for Pioneer Water Tanks

    The ring beam drawings specify the size, number and spacing of the reinforcing bars and ligatures to be used as well as the MPA rating for the concrete. Ring beams should be as level as possible and have no more than +/- 1/16” over any 5’0” (+/- 2mm over any 2m) of the circumference at the tank wall position and +/- 1/8” (+/- 4mm) over the entire ring beam. A survey chart will need to be completed and returned to your local installer for approval before the construction is started.

    The local Pioneer Water Tanks installer needs to ensure that foundation conditions are adequate. All water storage systems are subject to the local authority requirements so Pioneer Water Tanks also recommends local installers adhere to that authority for the tank location.
