| Research Abstract |
In Japan, many municiparities have become to receve more water for their waterworks from large-scale public water-supply entetprises especially since mid-1980s. On the other hand, these municiparities have abandoned more and more thier own water resources near at hand. So the author hypothesized that local water resources are apt to be more incautiously observed and less severely less severely preserved from pollution and that water-environments of many regions must be more and more polluted if the large-scale public wate-supply enterprices increase and prevail over local waterworks.
This hypothesis was actually proved to some degree through statistical analyzes, visiting and questioning the staff of waterworks of the muniuciparities which have come to receive water from large-scale pubric water-supply enterprises, questioning the inhabitants of the regions where municiparities' own water resouces were abandoned, and sennding postal questionnairs to the municiparities concerned. The prevailance of large-scale pubric water-supply enterprises owes to the initiatives of the central government and prefedtural authorities rather than municiparities'own wills. Such failure of autonomy of municiparities and the oversupply of water as its result have come to be prominent causes of water pollution in Japan.
