USING ANOTHER DIVER
To Examine Valve In Intake Pipe For Leak.
The waterworks committee decided at its meeting on Monday afternoon to make another attempt to discover the leaks in the intake pipe by securing another diver to make an examination of the valve 1,300 feet out, on Wednesday. It was thought that the valve may not be properly adjusted. The details of the tests were left to the chairman and the superintendent, and Ald. Carson announces that shore water will likely be pumped for a week and he wants the people to put aside a week's supply of drinking water tonight, so as not to drink the contaminated water that will be pumped. If the leak is not found at the valve, the joints of the lengths will be more thoroughly examined.
The committee decided to use every possible means to locate the leaks. Recommendations have been received from the city engineer, and Ald. Carson suggested that William Lesslie, who has had much experience in pipe laying, should be consulted. Ald. Ross thought that the Military College engineers might have some suggestions to offer. They might know of some new methods.
Superintendent Hewitt said that there were various methods to be employed if the committee desired. If the water pressure method failed, air, oil, or colored water could be used.
Ald. Carson first explained that the diver had gone over all the inner section of the pipe, and could not locate any leaks, when the pipe was under water pressure. He himself had then gone to City Engineer Craig and asked him if he had any suggestions to make. Ald. Carson said that the engineer had not given anything new except to advise that all the joints be cleared of mud, etc. He then read what the city engineer had to say:-
City Engineer's Recommendations
In his letter of the 26th, to the chairman, City Engineer Craig advised as "a short cut" that the valve 1,300 feet out should first be tested. Then if the leak still existed the joints from the wharf out to that valve should be tested under pressure, after the ? has been washed away from them. The engineer said he understood there were some weak spots in the intake on the outer side of the valve. A pressure even of twenty pounds can result, he said, would result in no great harm to such spots for the reason that if they cannot stand this pressure they should be repaired in some more substantial
Continuing, the engineer reported: "If the above measures are not sufficient to locate the leakage in the intake, it must exist at some one of the individual lengths of pipe when the valve and the joints have been tested."
