<br />I <br /> <br />I <br /> <br />deficiency rating assessed. Additional storage facilities/to meet fire <br /> <br />I <br /> <br />flow,' requirements should be elevated storage tanks. <br /> <br />Distribution Syste~. <br /> <br />The location and size of mains are shown on <br /> <br />I <br /> <br />Plate 1. The system consis.ts of 6", 4", 2" and 1" mains. Fire hydrants <br /> <br />and valves are located as shown on Plate I. Most of the mains are cast iron <br /> <br />I <br /> <br />with leaded joints with the exception of the 1" mains and part of the 2" <br /> <br />I <br /> <br />mains, which are galvanized steel pipe. Most of the distribution system <br /> <br />is undersized as far as delivering required fire flows and will require <br /> <br />I <br /> <br />augmentation or replacement with larger mains. There are numerous dead end <br /> <br />mains which need to be looped and several areas of the town will require <br /> <br />I <br /> <br />fire hydrant installations to meet current hydrant spacing criteria. Flow <br /> <br />I <br /> <br />tests were conducted on September 30, 1975 at various points throughout the <br /> <br />existing system and the results are tabulated in Table 6. <br /> <br />I <br /> <br />I <br /> <br /> Table 6 <br /> Fire Hydrant Flow Tests <br /> ** <br /> Allowable <br /> * Fire Flow <br />Hydrant Static Flow Measured @ 20 psi Type & Size Hydrant <br />Location Pressure Pressure Flow Residual Remarks <br />First St. & 53 psi 5 psi 4 psi Type A <br />Grant Ave. 331 gpm 270 gpm <br />Second St. & 50 psi 12 psi 7.5 psi Type A <br />Lincoln Ave. 453 gRm 399 gpm <br />Third St. & 54 psi 12 psi 6 psi Type A <br />Grant Ave. 405 gpm 361 gpm <br />Fourth St. & 53 psi 35 psi 17.5 psi (1) Type A <br />Lincoln Ave. 691 gpm 959 gpm <br />Fifth St. & 50 psi 46 psi 3.5 psi 917 gpm(l) Type B-very hard to <br />Lincoln Ave. 309 gpm close hydrant <br /> <br />I <br /> <br />I <br /> <br />I <br /> <br />I <br /> <br />I <br /> <br />I <br /> <br />I <br /> <br />I <br /> <br />-23- <br />
