Tests of Water Leakage
Superintendent George Cotter of the water department of Springfield, Ohio, recently made a series of tests on the basis of the amount of water which would flow through a leak of given dimensions at the average pressure maintained in the city’s water mains and the cost of the water lost at the rate charged by the city. Through a hole 1/32 of an inch in diameter 698.3 gallons of water flows each day, or 20,800 gallons a month. The cost per day is .069 cents and the cost per month is $2.08. A hole 1/16 inch in diameter passes 2,153.9 gallons a day and 64.618 gallons a month. The cost per day is .215 cents, per month $6.46. A hole 1/8 inch in diameter passes 4,665 gallons a day and 139,968 gallons a month. The cost is .466 cents a day and $13.99 a month. Through a hole 1/4 inch in diameter 14,580 gallons of water flows daily, or 437,400 gallons a month. The cost is $1.45 a day and $43.74 a month. The tests were made by passing water through holes of the exact dimensions for which figures are given at a pressure of 75 pounds. The water passed through the holes was metered by an ordinary meter and weighed to obtain scientific accuracy. If there was any shading of the figures at all, Mr. Cotter said, it was on the side of conservatism.
A friendly suit instituted against the city of Ashtabula, Ohio, by the Ashtabula Water Company was recently decided in favor of the company. The appropriation for city expenditures was not sufficient to allow the payment of $4,458.52, which was due to the company from the city for a half year’s hydrant rental, the safety fund, from which this should have been taken, not being sufficient to pay the bill. The friendly suit was the result, and money may now be taken from the sinking fund, it being necessary for a judgment to be procured against the city in order to do this.
