Excerpt from Society of Engineers: Established May 1854, Transactions for 1909 and General Index 1857-1909 There is a great charm in a gravitation scheme as the absence of machinery makes the supply so certain and so automatic, but in the present days of high - class pumping machinery, break downs can be provided against by the provision of spare units, and after all it is only a matter of finance whether the annual cost of pumping will exceed the interest on the additional capital necessary to construct works at a greater distance from the population to be supplied. When, however, the higher supplies are exhausted, as they already are to a large extent, we shall be compelled to utilise the lower catchment areas even if it becomes necessary to add the extra cost of lifting the water to that for the construction of impounding reservoirs for its storage. A further method of utilising to the fullest extent our present supplies will be by the creation of Water Boards, with a Central \vater Authority as a final Court of Appeal, who will be charged with the duty of dealing with the available waters in large areas, their sphere of authority being probably limited, not by our present county, town, or parochial limits, but by the area of the Watershed of a River or group of Rivers.
