Pond. In December, 1871, the gates at the outlet of the pond were raised, and remained opened until the twenty-eighth of the month, to allow the fish to escape from the pond. On the twenty-ninth of the month, the lower gates, on Alewife brook, at the Lexington Branch Railroad, were closed, to prevent the drainage from flowing back into the pond. In April and May, the gates at the outlet of the pond were open the entire time, to allow the fish to return to the pond. In September, the gates at the outlet of the pond were again opened, and remain open at the present time, during which time there has been a continual flow of water out of the pond. The following table shows the height of the water in the pond at the end of each month of the year. Engine House. There have been no repairs made on the buildings during the year. The small well-room has been connected with the large one, and the small pumps have been overhauled and put in working order, and were started the first day of November, 1872, and the working of the large pumping engine was suspended at that time, for repairs, after being in constant use for four years. We have at the present time 564 tons of coal on hand. There were 593,492,156 gallons of water pumped the last year, consuming 1,522,650 pounds of coal. The average number of gallons pumped daily was 1,626,006, an average decrease of 12,467 gallons per day (estimating last year's pumping at 300 gallons per revolution, the same as this year's pumping is made up). The daily time of pumping for the first eleven months of the year averaged seven hours and fifty-eight minutes. Force Main. During the year, four leaks have been stopped, all of which were in joints. On the 25th of December, 1871, the Y branch under the railroad track, connecting both sets of pumping engines, broke, and was removed at that time. The large pumping engine was connected with a straight length of pipe. In November, 1872, this connection was broken, and another Y branch was put in to connect both sets of pumping engines. On the twelfth day of November, the Y branch again broke, while the working of the large pumping engine was suspended for repairs, and the small pumping engines were connected with a straight length of pipe. Reservoirs. No repairs of any importance have been made on either during the year. It will become necessary to make some repairs on the retaining wall on the westerly side of the large reservoir, another season. Distribution Pipes. Nearly five miles of pipe have been laid the present season, making the total length of pipe in the city at the present time about seventy-two miles. Five hundred and four leaks have been |
