<br />town could not get accreditation for a water system at all. <br /> <br />According to the N.F.B.lJ., the total reqllired fire flow for <br /> <br />a town can be computed from a formula: <br />G ::. 1020 ,<p (:1- - 0.01 VT ) <br /> <br />where <br /> <br />G = required fire now in gallons per minute <br />p" popu1atio>l in thousands <br /> <br />So, for Rico: <br /> <br />G .... 102016-:sj (1 - 0.01 10.53 ) = 737.2 gal./min. <br /> <br />This flm, must be superi.mposed on a maximlJl~ dailY flow, ,lhich <br />'is 44.1 gal./min. or total reqllired flow is 781.3 gal./min. <br /> <br />This flow can be deli ve:t'edeasily with a six inch line to the <br /> <br />distribution point. <br /> <br />HOlo/ever, at this point, all existing lines are of four inch <br /> <br />maximum size, At this :point, we evaluated the present system and <br /> <br />detennined flows at all hydrants. We found that if all bad lines <br /> <br />were replaced by four inch lines and all four inch line:; that lTere <br /> <br />in good shape were left in place, there would be no way that the <br /> <br />N.F.B.U. requirements could be made in more than two of the town's <br /> <br />hydrants. We then reeva,luated the system, replacing all bad lines <br /> <br />with six inch lines and replacing scme four inch mains that were <br /> <br />still in good shape witl1 six inch mains. ~fe fOl)lld that minimum <br /> <br />N.F.B.U. standards could then be achieved with the six inch mains. <br /> <br />Since a community is rated by a deficiency point system <br /> <br />which involves notonJy the water system but the fire department, <br /> <br />fire service c~~unications and fire safety control, it would <br /> <br />be difficult to formulate a system that would make Rico a Class One <br /> <br />- 34 - <br />
