. conveniences of domestic water supplied with good pressure and in adequate quantities. As more development progressed an adequate supply of water for fire protection and domestic use became a necessity, but could not and cannot be furnished due to undersized lines. The above is not true for all of the development in Eagle, as many annexations and subdivisions were well-planned and the water mains which were installed were of sufficient size to provide good domestic service and fire protection. Raw water transmission: The raw water transmission line from the intake structure to the water treatment plant consists of: 4,500 feet of new 10" cast iron pipe; 1,000 feet of new 12" cast iron pipe; 12,144 feet of old 8" steel pipe; and, 10,560 feet of old 10" steel pipe. The location and ~izes of the raw water transmission line are 0' . shown on Exhibit D at the end of this report. It appears that the tleW 10" cast iron pipe and the new 12" cast iron pipe were laid in reverse order, It is customarily sound engi- neering practice to ins tail the largest pipe where the pressure head is the lowest and the smailer pipe where the pressure is the greatest. The older pipe consigts of a welded steel pipe which has not lasted as long as steel pipe shoold last because cathodic protection was not added to the line during or after construction. Had the steel pipe been properly protected from the corrosive factors in the soil, the line, even though not adequate to deliver the full capacity of the treatment plant, would still be adequate for the town's needs, How- ever, since the pipe was not cathodically protected and provision made to protect it from corrosion, the line now needs to be replaced. - 9 -
