WATER REPORT OF GREENFIELD

WATER REPORT OF GREENFIELD

The report of the Water Department of Fire District No. 1, of Greenfield, Mass., for the year from January 1 to December 31, 1915, states that the year saw many new buildings connected to the water system and was a record season for the number of new connection of which there were 100. The commissioners are Charles C. Dyer, William F. Aiken and Thomas L. Lawlor. George F. Merrill is superintendent. The water works were constructed in 187a and are owned by the Fire District. The source of supply is reservoirs on Glen Brook, wells near Green River. The mode is gravity and emergency pumping. The reservoir capacity is: upper reservoir, 45,000,000 gallons; lower reservoir, 26,000,000 gallons; Rocky Mt. reservoir, 2,500,000 gallons. The builders of the pumping machinery were the Platt Iron Works Company. The total pumpage for the year in gallons, by Venturi meter, was 11,250,000. The estimated population supplied is 12,123 and the total consumption for the year was 427,294,000 gallons of which 148,726,000 gallons passed through meters. The percentage of consumption metered was 34.81. The average daily consumption was 1,170,008 gallons, being 97 gallong to each consumer; 5,708 feet of distribution pipe were laid during the year and the total in use is 49.7 miles. There were 15 hydrants added making 322 in use. The range of pressure in mains was 65 to 135 pounds. The total number of services is 2,506. The number of meters added was 29. The number in use being 263. The percentage of services metered is 10.5 and the percentage of receipts from metered water is 34.85. The commissioners and superintendent say in the course of their report: The conditions for the first six months of the season were such that they indicated, that if we had a normal summer season, we should have a record drouth year. On account of the conditions last fall, winter came on with very little water in the ground, and it was necessary to start pumping in January and continue for about a week, when heavy rains filled the reservoirs. During the spring months there was considerable shortage in rainfall, and it became necessary to pump for about a week. After this period there was considerable surplus over the normal amount of rainfall, and no pumping has been required, with the exception of a few days’ pumping when the mains from the reservoir were broken by high water. The total cost of operating pumping station was about $270. About the 10th of August wc had very high water in the Glen Brook watershed, also on Green River, due to excessive rains, which caused considerable damage to our pipe lines. The 14-inch main was broken in the gorge, below the lower dam near the dam, also the 8-inch pipe was broken in two places at about 1,500 feet below the dam. These two breaks occurred at about the same time, and were, fortunately, quicklv located, so that the water could be shut olT in such a way that a supply could be obtained from the new pumping station. The 6-inch main which crosses Green River near the ballgrounds was also broken in two places, and several days after, the 8-inch main which crosses Green River near the Shelburne Street bridge was broken. These breaks in Green River were due to the high water scouring out the bed of the stream underneath the pipe. The 8-inch pipe at the Shelburne Street bridge was taken out. and a new 10-inch pipe with flexible joints was laid in its place. As this could not be done immediately on account of the special pipe required, it was necessary to lay a temporary line of 6-inch pipe across the bridge, about 500 feet, in order to supply the section of the town west of Green River. Also considerable damage occurred at the upper reservoir, a portion of the side wall of the spill-wav below the reservoir being undermined and cracked so badlv that it had to be removed. Also the concrete paving in the lower portion of the spillway was undermined and a considerable portion of it carried away. During the high water the water flowed over the top of the dam, as the spillway section was not large enough to carry the amount of water flowing. The spillway on this dam has now been lengthened, so that it has about fifty per cent, more area, and should avoid further overflow of water over the top of the dam.
