Options for installing a 10000 litre JoJo vertical water tank

The basic principles for installing a polyethylene vertical water tank apply to a range of water tank sizes but become more important as the water tank capacities increase. It is critical to install water tanks properly, especially the larger 5000 litre, 10000 litre, 15000 litre and 20000 litre water tanks – these carry many tonnes of water!.

The 10000 litre water tanks are rated to carry 10 tonnes of water – bear this in mind when placing the tank and filling it with water.   There are basically to installation methods approved by JoJo Tanks:

1. Install tank on cement, ground=level platform or base;

2. Install tank on a certified steel water tank stand.

What follows is a brief outline of the above two options:

1. Guidelines for a cement base or platform for a 10000 litre water tank

• JoJo Tanks advise that customers build a cement base for the tank using 25MPA cement.
• The width of the platform should be at least 50mm wider than the base of the tank, which is 2200mm in diameter.  So the cement base should be at least 2250mm x 2250mm square.
• There must be no overhang and the height/depth of the cement platform should be at least 150mm.
• JoJo Tanks suggest that the earth is compacted very well before the cement base is laid
• Builder must ensure that the base for the tank is 100% level.

2. Water tank stand installation

JoJo Tanks supply steel water tank stands that are manufactured and certified by a structural engineer.  The tank stands are supplied in kit form, ready to bolt together.  There are tank stands for 5000 litre vertical water tanks and tank stands for 10000 litre water tanks available in the following heights:

• 1.5 metre tank stand
• 3.0 metre tank stand
• 4.5 metre tank stand
• 6.0 metre tank stand
• 9.0 metre tank stand

The installation of the tank stands requires a concrete base block for each of the four tank stand feet; the dimensions should be at least 900mm long x 900mm wide x 600mm high.  Full installation guidelines can be obtained with the purchase of JoJo tank stands.

A 10000 litre JoJo vertical water tank is quite heavy even when empty so care must be taken when hoisting/lifting the 10000 litre tanks up on to the tank stand platforms (especially for tank stands 3m and higher).

It pays to observe proper installation procedure when installing the bigger water tanks in order to avoid damage to the tank itself and to surrounding infrastructure.
