The installation of a extra-large water tank, particularly tanks in the 10,000–30,000 litre range, needs careful planning. Some of the most common mistakes are:
Poor ground preparation – Installing a water tank on uneven, soft or unstable ground can cause movement and place unnecessary stress on the tank. The base should be level, solid and capable of supporting the considerable weight of a full tank.
Underestimating the weight of the water – 1 Litre of water weighs approximately 1kg, so a 25,000 litre tank can hold around 25 tonnes of water, excluding the tank itself. Consider this when design and constructing the supporting base.
Making the base too small – The entire bottom of the tank should be properly supported. Avoid positioning the tank where parts of the base overhang the foundations.
Not checking access before delivery – Large tanks require significant clearance. Narrow gateways, overhead cables, trees, buildings and restricted roads can all create problems when we deliver your tank.
Lifting or moving the tank incorrectly – Our extra large tanks come with pre-moulded need to be handled using appropriate equipment and lifting procedures. Incorrect handling can damage the tank before it is even installed.
Incorrectly connecting pipework – Heavy or poorly supported pipework can put excessive strain on tank outlets and fittings. Pipework should be independently supported and installed so it doesn't transfer loads to the tank wall.
Overtightening fittings – Applying excessive force to threaded fittings, valves or connections can damage components or the tank connection.
Ignoring drainage around the tank and inadequate overflow – Water should not be allowed to collect around the tank's foundation. Good site drainage helps protect the base and maintain a stable installation. During heavy rainfall or rapid filling, water needs somewhere to go. An incorrectly sized or positioned overflow can result in flooding or other installation problems.
Failing to plan for maintenance access – Don't position the tank so tightly against buildings, fences or other tanks that valves, outlets, lids and other components become difficult to reach.
Installing the tank before planning all connections – Decide where pumps, filters, valves, overflows and other equipment will go before putting the tank into its final position.
Not following the manufacturer's installation instructions – Requirements can differ depending on tank size, design, intended contents and site conditions. For very large tanks, the manufacturer's installation guidance should always take priority.
