What features should the ideal underground water tank have?

Underground water tanks can be a better alternative to standard above-ground water tanks but they must be properly constructed and designed to withstand pressure exerted on the walls when buried underground.

Here are some features which the ideal underground water tank should possess:

    • The underground tank should be of a useful capacity for storing worthwhile quantities of water; a tank in the 5000 litre to 10000 litre capacity range is usually best
    • The walls should be of sufficient thickness to withstand external pressure from surrounding soil and added strengthening ribs help to further increase the tank’s robustness
    • The shape of the underground water tank is important from a technical point of view; cylindrical tanks are better able to spread external pressure evenly compared to square or rectangular underground tanks
    • Type of material used to make the tank can influence longevity; generally, high quality polyethylene underground water tanks offer the best combination of corrosion resistance, resistance to cracking, ease of installation, affordability and capability of storing potable water for long periods
    • Should be manufactured using a rotational moulding process so that there are no weak seams to potentially crack or split
    • Should be colour-coded so that an underground conservancy tank or septic tank is never used for storing potable water
    • Ideally the brand of underground water tank should be well-known and should offer a guarantee as well as installation guidelines and after sales back-up and information.
