BTW 10000 litre Plastic Water Tank from Big Water Tanks Installation Guide

Delivery

Delivery of your Big Water Tank is to the entrance of your property.
However, our driver has the discretion to deliver onto your site, provided that you have cleared a large access way.
An able-bodied person must be available on-site to assist with tipping the tank off the trailer.

Site Preparation

Remember that Big Water Tanks are for ambient temperature, potable water storage only.
Site preparation is the responsibility of the purchaser. Contact BWT should you have any questions.

Select an area which is FIRM, LEVEL, STABLE and free draining.
Ensure that the site area is free from any sharp objects such as stones and roots
Do not place the tank on beams or a wooden pallet with interval spaces.
If the location is on a sloping section ensure that the mounting site, surrounding the area is level and will remain free from any erosion in the future.
When lifting the tank use all lifting lugs and never lift the tank with water in it. A10000 Litre tank weighs 225kg when empty and about 10 tons when full.
A compacted sand bedding area of at least 100mm deep is required which is retained so that the sand cannot wash away.
There should be a minimum sand or GAP7 base of at least 250mm more on either side of the tank refer to Figure 1.
The tank can be placed on a smooth concrete surface however the pad must be constructed to handle the weight of the tank when full.
Failure to do so will result in the concrete cracking which will provide an uneven surface and unnecessarily stress the tank.
Take care with the preparation of the site area and when handling the tank.
Once in place inspect around the bottom of the tank to ensure that there is no gaps between the surface and tank.

Installation

When installing the tank ensure that all pipe work from the tank is supported.
It is important not to allow the weight of the pipe work to rest on the wall of the tank without being fully supported.
A flexible hose must be installed between the out let fitting and pipe.
This provides less stress on the tank fittings by allowing for pump vibration, surging and expansion and contraction of the tank.
Water pumps must not be directly installed to the side of the tank.
Air and water must be able to escape at the same rate as the water is being pumped in or out to avoid a possible internal pressure or vacuum.
Pipe the overflow away from the foundation to prevent erosion
A1/2 – 2″ Hansen tank fitting is installed in the bottom of the tank.
We recommend that thread tape be used on all fittings to avoid leaks which could lead to possible erosion and under mining of the tank foundation.
Do not over tighten fittings when installing in to the tank.
The tank may be buried up to 500mm.
Only use clean back fill when filling against the tank and
Do Not Bury over 500mm from the bottom of the Tank
Please Note: Tanks smaller than 1000Lmay NOT be buried
