Extending Intake Pipes at Erie.
The report of the water commissioners, of Erie, Pa., sets forth with some detail the work now completed of extending the intake pipes of the water system beyond the bay and out into lake Erie. The intake was extended 9,334 ft. across a peninsula and out into the lake, 60 in. pipe being used. The intake is at present 5,100 ft. from the shore A crib 40x10x19 was sunk where the water is 35 ft. deep, insuring a depth of water over the intake of 26 ft. at United States mean level. An emergency intake was also located on the peninsula and a bulkhead placed over the intake in the bay, discontinuing its use as a source of supply. The entire length of the intake now is 17,041.43 ft., and believed by the commissioners to be the longest single piece of submerged 60-in. cast iron and steel intake pipe in the world.
Since the installation of the new intake the typhoid fever rate has declined to a very small percentage, which fact alone justifies the abandonment of the bay as the source of supply, and proves conclusively the wisdom of the course pusued hy the commissioners. One of the sedimentation basins on the peninsula has been in use for some time, and the second one is nearing completion. The entire cost of all this work has been paid out of the revenues of the department.
