In this strategy, the population is supplied with drinking water from large, centralised water treatment plants. The treated water is piped to all the communities in the geographical area served by the treatment plant, thus requiring an extensive pipe network, so as to reach even the most remote communities. The treatment plants could be managed and operated by the larger municipalities or, more likely, by the Water Boards in that region. Generally, these plants should be well managed and operated effectively due to availability of sufficient O&M funds and qualified human resources.
