Sectional Water Tank Installation Requirements
Sectional Tank Installation Guidelines
The tank type determines the type of foundation that may be used for installation. Base guidelines are provided for each sectional tank ordered.
Externally Flanged Base (EFB) Sectional Tanks
Option 1 – Solid bearers
Concrete dwarf walls – placed at 1000mm centres for metric tank panels. As space is required underneath the tank, externally flanged base tanks must be placed on an elevated structures outlined in the image.
Option 2. Steel supports
Parallel steels beams placed on raised steel supports. Steels placed at 1000mm centres metric tank panels.
Option 3. Secondary Steels
Concrete dwarf walls with parallel steels running perpendicular to dwarf walls. Primary walls centres no less than 750mm. Steels placed at 1000mm/500mm centres metric tank panels. This arrangement becomes necessary where access is restricted due to primary supports at 500mm centres.
Sectional Tank Support and Clearance Requirements
Space Requirements for Sectional Tank Installation
| A | B | C | D | |
| Tanks up to 3m deep | 600 | 425 | 750 | 500 |
| Tanks 2m – 2.5m deep | 600 | 525 | 750 | 500 |
| Tanks 3m – 4m deep | 600 | 625 | 750 | 500 |
Clearance dimensions in mm
Clearance may be varied by agreement for small tanks where access is deemed suitable.
Ladders with hoops will require a space of at least 1030mm.
Sectional Tank Base Requirements
Option 1 Concrete plinth
Flat concrete plinth- ensuring the plinth is level and that it extends 150mm beyond the tank internal length and width dimensions
Option 2 Steel supports
Parallel steel beams – placed at 500mm centres metric tank panels.
