have come from which have been keeping the Morris reservoir up somewhere near normal. Eventually a third reservoir may be constructed back behind Morris, which would make chain of three in the north- west region.
 The East Mountain reservoir has storage capacity of about 150 mill lion gallons, but has to supply a great many people, so that 1t has been found necessary to use pumps from the Wigwam reservoir to sup- ply some of the people in the area. When the total amount pumped from the Wigwam reservoir is not consumed by people in the East Mountain area, the surplus flows into the East Mountain reservoir, which also draws a good deal of its water from the one at Prospect. The Wigwam pumps operate under nor- nal conditions from 6 a. m. to Il p. m. ad it is only on very rare oc- casions that they are allowed to run all night, according to MT. Cas- sin. Waterbury is not only able to furnish its own supply of water, sufficient to meet any but the most extreme emergencies, but it regu- larly sells water to the Hillcrest re district in Middlebury.
 Variation
 The figure of nine million gallons 8 day for the average consumption of Waterbury during the summer of course varies a good deal with the temperature. And the figure, may vary by few thousand gallons on different days of the week. Monday, MT. Cassin said is the day when there Is the greatest demand for water. This is natural, since Monday is the traditional wash day, and since on Monday the factories are opening up for the week. Then there are certain irregular variations in con- An increase can usually be noted on te days when the water in the Hamilton and Chase park swimming pools is allowed to run off, and a fresh supply of water is drawn to fill them again. In an of course, great deal of water could be saved by not allow ing fresh water to be drawn to fill these pools.
 The water pressure varies also in different sections of the city. At the center, the pressure is just about 100 pounds, while in the hill regions the pressure may fall as low as 25 pounds. The firemen have to take these pressure differences into con- sideration in obtaining a sufficiently strong force of water to fight any fire.
 Water Mains
 The city's water mains, MT. Cas- sin said, vary from four to thirty six inches in diameter. Not many of the mains laid nowadays are less than six inches.
 One of the things that the aver age citizen does not think much about in connection with the citys water supply MT. Cassin feels, is the extraordinary care that has to be taken of the watersheds of the res- ervoirs to avoid impurities getting into the water. A state health in- spector is liable to come through town at any time without advance notice, he said, and take samples of the water in the various reservoirs, and report on them. Hence 1t is necessary that the water in all the reservoirs be up to te states stand ards all the time. For removing the from the water, the city relies on the most modern type of chlorinators, made by firm in N. J.
 In short, the water supplied to the citizens of Waterbury need oc- ,asion nobody any worry either as to quantity or quality. The supply is adequate for any emergency and the purity is guaranteed by the effective measures taken by the Water Bureau.
