Introduction

Permalog® Plus is the very latest in a highly successful line of permanent and semi­permanent leak noise loggers. This logger can be used as both a traditional leak noise
logger, and as a "drive by" logger.

Permalog® Plus leak noise loggers are deployed throughout the water distribution net-work
to provide continuous surveying of leakage. Each Permalog® Plus unit adapts itself
automatically to its environment. If no leak is present a signal is transmitted to indicate
normal background conditions, however, as soon as a possible leak is detected, the
Permalog® Plus unit enters an alarm state and transmits a signal to indicate a leak
condition. The logger also incorporates an LED to display the leak status visually.

Following a rise in unaccounted for water, or at standard intervals, a leakage patrol is
carried out in the area using the Permalog® Patroller module. Leak status information from
the loggers is displayed on the PDA screen of the Patroller module and stored in the
memory.

With no cables or hard installation, Permalog® Plus is simply fitted to a metal fixture within
the chamber (usually a hydrant or valve) and left alone. Logging times, Patrol times and
Transmission times are fully customisable ensuring the operator gets the most benefit from
the system and can configure it to their advantage. With integrated Bluetooth technology, the
Permalog® Plus logger offers easy management through the PDA and Patroller Interface
Unit. Permalog® Plus can be fully configured without having to be removed from the
chamber.

Operational Benefits

• 100% of distribution system permanently monitored.

• Finds more leaks more quickly than traditional methods.

• Responds rapidly to new mains bursts, improving service to customers.

• Automates and de-skills leak surveying, eliminating human error and finding leaks
that would otherwise be missed.

• Eliminates "stop tap bashing" (surveying using listening sticks).

• Operates independently of the size, structure or integrity of the area being monitored.

• Completely non-invasive method with no detrimental effects on supply to customers
(preferred alternative to step testing).

• Improves overall detection efficiency and motivation by enabling skilled staff to
concentrate on finding "known" leaks and avoid wasting time in no-leak areas.

• Operates continuously for up to 5 years (dependant on configuration), enabling a low
leakage level to be maintained easily.

• Bluetooth and RF technology allow wireless configuration on site.

• Logging can be fully customised to fit customer’s requirements.

Benefits of Use

Economic Benefits

• Survey costs cut by >90% with elimination of surveying using listening sticks

• Dramatic productivity gain - one person can survey several DMA's (District Metered
Areas) per day.

• Record low leakage levels attainable and easily maintained.

• Low installation cost and no maintenance costs enable rapid payback, with in-
creasing profits per year.

• No night work required for leak surveying.

• Negligible incremental cost of additional surveys.

• Highly attractive return on capital employed.

• Lower leakage level reduces cost of water into supply.

• Demonstrates high technology benefits to regulator, customers, shareholders and

international clients.

With over 200,000 units deployed worldwide, it’s easy to see why the Permalog range is one
of the most highly respected Leak Noise Loggers in the industry. HWM-Water Ltd, your
