The reservoir tank is placed at a point near the village that is higher than all the houses that are to be supplied. The tank must be large enough to ensure an uninterrupted supply during the times of day when there is the peak demand. The tank is thus sized according to the size of the population and the flow rate from the spring during the dry season. The tank in this system is a 13 000 litre tank made from reinforced concrete using a pre-fabricated mould. The tank has a vaulted brick roof, a method that is both cheaper and quicker than making a reinforced concrete roof.
