<br />V-3 <br /> <br />, <br /> <br />The chlorinator is manufactured by Capital Controls Co. and is housed <br /> <br /> <br />in a corrugated, metal enclosure on top of the settling tank. This <br /> <br /> <br />chlorinator is a direct feed type. Chlorine bottles are placed inside <br />the enclosure on a bathroom scale. <br /> <br />The housing for the chlorinator is inadequate. In order to insure <br /> <br /> <br />disinfection by the constant operation of the chlorinator, the <br /> <br /> <br />chlorinator should be housed in an enclosure where the temperature can <br /> <br /> <br />be maintained at 500 F. minimum. The reason for this is that at <br /> <br /> <br />temperatures below 500 F., chlorine gas will combine with water to <br /> <br />form crystalline chlorine hydrates. This can cause trouble at the <br /> <br />pressure-reducing valve and could clog the orifice. <br /> <br />STORAGE FACILITIES <br /> <br />The existing storage facilities consist of three steel tanks located <br /> <br /> <br />above the Town to the north as shown on Drawing No.2 enclosed. <br /> <br /> <br />Flow into and out of the tanks is provided by steel piping laid on <br /> <br /> <br />the ground surface. The high water level in the tanks is controlled <br /> <br /> <br />by individual overflow pipes that discharge to a surface drainage <br /> <br /> <br />ditch behind them. The incoming flow and discharge flow to the dis- <br /> <br /> <br />tribution system is metered; however, the overflow is not. Thus, <br /> <br /> <br />the source yield cannot be accurately determined at the storage site. <br /> <br />Since tanks and piping are above ground, they are exposed to winter <br /> <br />freezing potentials. <br /> <br />. <br />
