Water Supply Service Level I vs. Level II vs. Level III

Level I (point source) is a protected well or a developed spring with an outlet but without a distribution system, generally adaptable for rural areas where the houses are thinly scattered.A Level I facility normally serves an average of 15 households.

Level II (communal faucet system or standposts) is a system composed of a source, a reservoir, a piped distribution network,and communal faucets. Usually, one faucet serves 4 to 6 households. Generally suitable for rural and urban fringe areas where houses are clustered densely to justify a simple piped system.

Level III (waterworks system or individual house connections) – a system with a source, a reservoir, a piped distribution network and household taps. It is generally suited for densely populated urban areas.
