Leak Detection
|
Leak detection is a cornerstone for water loss management. Much economic and procedural emphasis is often placed on
end-of-pipe solutions such as conservation practices and programs, including the installation of water-saving devices
and meter calibrations. Leaks from buried mains, valves and service connections are often ignored or simply “missed”
because they are out-of-sight and mind. Unfortunately, their silence belies their costs.

Did You Know
“Most nonvisible underground leaks are estimated to have an average life of two years”
“A pin-sized water leak at 40psi loses 2000 gal/day. That’s the equivalent water used by a family of four in a week”

According to the American Water Works Association (AWWA), an average of 20% of treated water is lost to leaks
in water systems across the United States. Based upon EPA cost data, the following chart is an eye-opener:

At Envirologics, we believe that a leak detection survey is an essential, early requirement in properly assessing the
condition of aging water pipeline systems. The right survey means and methods will support and enrich decisions related
to loss management.

At Envirologics:
- We believe in measurement over reliance on historical data.
- We believe in measurement over random sampling.
- We believe in measurement over modeling.
