Consider how much water can be lost
through a pinhole leak over a period of a month. “Unaccounted for” water
is a major source of lost revenue for most utilities.
Water loss as a result of a leak .63 cm diameter (1/4”) can mean a loss
of 14,952 gallons per day. If undetected for a period of 34 days, over ½
million gallons are lost, plus resultant water damage or underground
water undercutting. The following table shows leak sizes and their
approximate loss in the gallons from a pressurized 60 psi pipeline. A
pinhole leak can mean an average loss of 18,000 gallons of water per
quarter, equaling normal demand from the average family home.
Besides reducing operating expenses, in many cases you can delay or
eliminate capital expenditures for expanding water supplies by stopping
