NSW: Water saving technology to be trialled across Sydney

SYDNEY, Aug 24 AAP - A revolutionary leak detection device designed to save water will
be trialled at 12 large water mains across Sydney.

The Sahara leak detection system has been successfully used in the United States and
Middle East, Water Utilities Minister David Campbell said today.

The technology, developed in the UK, works by placing a sensor inside a pipe, which
then travels along it with the water flow for up to two kilometres.

If the sensor passes a leak, it detects the sound it generates and alerts the system's operator.

Because the sensor travels within the water main, it can detect leaks in large diameter
pipes made from any material.

The technology will be trialled at locations including Beecroft, Killara, Strathfield,
Ryde, Eastwood and St Ives over two weeks.

"The NSW government has made it clear that reducing leakage is a key priority for Sydney
Water," Mr Campbell said.

"It (Sahara) has proven to be an effective tool in locating leaks in pipes measuring
250mm or more in diameter and can be used without interrupting the water supply."
