The total amount of water required annually for the East canal is 748,340,000 ───────────── Total 2,112,960,000 ───────────── In addition to which there is the Meurthe branch, requiring 462,210,000 ───────────── Making a grand total of 2,575,170,000 ───────────── Besides the above artificial sources, the canals are fed by springs at Vacon, and by the Moselle, &c. The arrangements at Pierre-la-Treiche and at Valcourt are nearly similar. There are two turbines, actuating force pumps, capable of raising from 143 to 198 gallons per second to a height of 131 feet 3 inches, through a line of cast-iron pipes of 2 feet 7½ inches diameter, delivering into an open duct connecting with the east end of the Pagny Reach of the canal. This duct commences at Pierre-la-Treiche, and is 8¼ miles long, and feeds both canals. £ The cost of these works was 51,920 Of which the pumping station at Pierre-la-Treiche cost 15,616 And the pumping station at Valcourt 26,908 The steam pumping-station at Vacon is near the west end of the Pagny Reach. The pumps are 250 H.P., and capable of lifting 8,804,000 gallons per twenty-four hours to a height of 121 feet 4 inches, or 110 gallons per second. The water is conveyed into a duct, which also carries the water from the Vacon springs, and empties into the Pagny Reach. The reservoir at Paroy has an area of 180 acres, and contains 376,371,000 gallons. The dam is 1378 feet long, and 18 feet 3 inches high; the cost of construction was 20,800_l._ The canal traffic in 1884 amounted to 634,936 tons.[68]
