Without a network management system, the utility operator has little insight
into the exact pressure and rate of flow available to each consumer in the network
other than a rule of thumb that assumes the network is performing properly
and is subject to normal consumption.
With the Aquis Pressure Optimization module
the operator can
Reduce the typical supply pressure by between 10 and 20%
Reduce leakage through existing leaks by 10 to 20%
Reduce the risk of additional leaks
Reduce pumping costs by between 5 and 10%
giving a saving in CO2 emissions
by reducing energy consumption up to 5%
The return on investment is typically less than 2 years.
With the Aquis Pump and Reservoir Optimization Module the operator
can reduce the electricity consumption by 10-15%
and reduce the CO2 emission with 10-15%
The return on investment is typically less than 2 years.
Both the Pressure Optimization and Pump and Reservoir Optimization modules
draw on the Aquis historical database and external data sources
such as weather forecasts
to predict likely demand profiles
based on historical data and expected weather conditions.
Network performance is never perfect
and consumption can fluctuate.
To take account of this, the un-managed network
must always operate at a higher pressure than necessary,
simply to ensure a margin of safety to meet demand.
For the un-managed network, this strategy implies
a considerable waste of energy
in maintaining a pressure higher than required
together with the need for pressure control valves
throughout the system
to limit excess pressure where it is not required.
Excess pressure operation also causes more leaks
typically in the least accessible parts of the network
incurring downtime, reduced service,
extra maintenance costs and the waste of water.
With the Aquis Pressure Optimization Module,
the network can be operated within tighter parameters
ensuring adequate pressure all the time
without wasted energy and unnecessary leakages
With the Aquis Pump and Reservoir Optimization Module,
the operator achieves additional control of pumping stations and reservoirs
enabling the selection of multiple supply sources at the optimal cost
to meet the demand at any given time.
