Abstract
A plant (200) for treatment of drinking water from raw water has a treatment tank (202) which is supplied with raw water and a storage tank (204) placed downstream of the treatment tank. The treatment tank supplies water on demand to a point of use (224). The treatment tank and the storage tank are connected by a conduit (206), with a pump (208) to feed water from the treatment tank to the storage tank, and by an overflow pipe (210) to feed water back from the storage tank to the treatment tank. The pump is activated by a command device to feed sufficiently treated water to the storage tank when water is consumed at the point of use and when water in the treatment tank is re-ozonized at intervals between times of consumption of water at the point of use. In the latter case, water from the storage tank flows back to the treatment tank through the overflow pipe so that it can be reozonized in the treatment tank.
