To Increase Chicago’s Water Supply.
Plans are being prepared by First Assistant Engineer Feind of the city engineer’s office of Chicago, in accordance with a new suggestion made by the Mayor, looking to furnishing the city with an increased supply of water early next summer.
The idea of building a tunnel from Sixty-ninth street to the Town of Take section was practically abandoned, because of the great cost of construction, as was Mr. Feind’s idea of extending the North shore inlet 3000 feet, because at least eight months would be required for the work. The Mayor believes the solution of the problem to lie in utilizing, with as little delay as possible, the pumping engines in the new Fourteenth street pumping station, which, it is expected, can be got ready for operation by spring. These pumps will draw water from the twin tunnels now !>cing excavated under the lake from the foot of Park Row. These tunnels are at present extended over 9000 feet. They are yet to extend td similar tunnels projected westward from a crib sunk two and one-half miles from the shore. It was hoped to open tunnel communication with this crib some time during the coming summer, but recently the contractors met with delay, and it cannot now be predicted when the crib will be reached. Here an inlet was to have been made and the work of pumping begun while the remainder of the tunnel to the five-mile crib was being finished.
The Mayor’s suggestion to the engineering department now is that an inlet crib he sunk at the end of the present completed tunnel. At the shore ends the two tunnels merge into one, and here he thinks a bulkhead might (>e constructed which would allow one tunnel to be used by the pump while work could be continued in the other. Mr. Feind is, however, quoted by the Chicago papers as saying that he does not believe the scheme practicable, as it would cost at least ft 50,000, and he thinks it would take much more time than the Mayor anticipates.
