In the perfect network, all water produced by the production facility
will find its way through the consumption meters of paying customers.
With no leaks in the network, all water will be revenue water.
In the real world there is no perfect network.
The reduction or elimination of non-revenue water
represents the greatest potential economic saving for any water utility.
Whilst some leaks are due to sudden events such as damage to an underground
water main by contractors, most leaks are small and develop gradually
Often invoked or aggravated by excess water pressure at inherently weak points
in the network, such as joints, valves and the locations of previous repairs.
The presence of many undetected small slow leaks in the network
forces the operator to compensate for loss of service pressure
by increasing the pressure at the production facility
consuming more energy and subjecting the network to further excess pressure.
A vicious circle from which it is hard to escape.
With the Aquis Leak Detection module the operator can
Reduce water loss by 10% or more
Reduce loss through existing leaks by 10-20%
Reduce the risk of additional leaks
Reduce energy consumption and emissions by up to 5%
Reduce the use of chemicals
and improve water quality
With Aquis Leak Detection the distribution network is monitored
in several leakage control zones, for which the consumption is logged
over the latest 24 hour period and the result compared with data
from the same period in recent weeks.
Anomalies between the current sample period and historical data
will usually be due to new leakages
the locations of which may be pinpointed within the defined detection zones.
Aquis Leak Detection focuses on the water flow in the network
during periods of known minimum consumption typically at night time
to monitor changes in the background leakage level.
By monitoring the network in manageable zones,
identification and location of any leakages is possible.
Aquis Leak Detection enables the operator to define
leakage alarm thresholds, which when exceeded
will automatically invoke alarms both at the operator
