10000 Litre Underground Water Tank

Water within the soil is capable of exerting considerable hydrostatic pressure, therefire, other than in the most free-draining sand or gravel soil, Ecosure Tank must be encased in at least 230mm (9 inches) of concrete.

1. Excave to the tank diamentions, allowing 230mm (9 inches) minimum clearance around sidewall and base of the unit. Level the base of the excavations. If levelling pegs are used they should be placed well away from the tank.

2. Ensure that any water is pumped from the excavation during installation.

3. Line the walls and base of the excavation heavy duty plastic sheeting to act as a waterproof membrane.

4. Pour a concrete base to 230mm (9 inches) minimum, and level.

5. When base is hard, place tank centrally in hole and ballast with approximately 1/4 of its total volume of water.

6. Backfill around tank with at least 230mm (9inches) of contrete allowing 150mm (6 inches) overlap onto curved tank top. Ensure that the concrete is not too wet and that it is tamped in around the tank.

Do not use a vibrating poker

7. It is most important that you progressively fill the tank with water to level of the backfill in order to stabilise pressure on the tank. This water should remain in the tank until the concrete have fully hardened.

8. Apply a mastic seal between the joint of the joint of the curved tank top and concrete to prevent ingress of water.

9. The tank screw top lid is designed to prevent ingress of dust, dirt and vermin, it is NOT to be walked on or buried or buried such that soil is in direct contact contact with the lid or top of the tank.

10. Where the storage tank is to be totally covered a suitably strong cover, such as a railway sleepers or a reinforced concrete slab must be placed over, but not in direct contact with, the lid.

Potable Water

The Ecosure CT Range of Storage tanks are suitable for potable water when fitted with the optional Bylaw 30 Kit and installed so as to comply with the relevent bylaws. Your water authority should be consulted if you have any doubts about installation

Durability

Ecosure Storage Tanks are manufactured from U.V stabilised medium density polyethylene by the rotational moulding process, which produces a tough, stress free, one piece moulding which is highly durable. It must be noted the Storage Tanks are not indestrucible and should, therefore be handled with care. Wherever practical, the installation should be shaded from direct sunlight.
