Anderson, City Engineer 3’irUECTs Report Requested by Howard Oomcn, City Attorney, for later Investigation® (Continued) For a town of tills size, the water storage capacity should bo sufficient to meet the needs of the community for at least a hO-hour period should -to source of water become unavailable through damage. In considering the storage requirements, irrigation water could be. eliminated in favor of the domestic consumption so that a minimum storage capacity should be between 12 and 1$ million gallons® Lack of stand pipes or elevated water towers to maintain equalized pressure throughout the lines puts an added lord, on the pumps and even with this added load it still will not give the proper equalisation of pressure. All distri­bution mains should be looped to go in such a way that positive pressure will pass through all the lines at all times. These lines should also be equipped with pressure relief valves, pressure regulators and sufficient shut-offs so that Then repairs are being effected or other work being done on the pipe lines that the vjater can be by-passed and be made available to all users except where pork is going on® Sufficient reserve supply sources 'should always be maintained so that these reserves can be used in case of a failure from any of' the other sources. It is apparent from various pressure failures x’iiich occur throughout the water distribution system that these features have not been fully complied with. 1* G. /mderson, City Engineer Y.CAigh Attachments: Reports
