for which the technical term is Non-Revenue Water or Unaccounted
for Water. Out of the total amount pumped into the distribution
network, a municipality is able to supply to the consumers only
60% to 80%. This is due to the water loss as a result of leakage
in the pipeline network of the various neighborhoods.
The solution proposed for this problem is the Smart Pressure
Reduction Controller (SPRC), which integrates elements of
hardware, software and hydraulics.
The SPRC provides a comprehensive solution for the leakage
problem by actively controlling the Pressure Reducing Valves,
found in any municipal water supply system at the point where the
piping network of a neighborhood is connected to the city main
water system.
The SPRC dynamically changes the pressure applied to the network
according to the actual demand for water, resulting in
significant leakage reduction.
Throughout the daily demand cycle the SPRC considerably decrease
the leakage, which tends to increase greatly especially during
night, when pressure grows due to diminished demand.
The SPRC is:
* An electronic/hydraulic device that dynamically manages
Pressure Reduction Valves - adjusting the pressure applied to the
network relative to actual demand
* Easy to install on any existing hardware
* Robust and reliable even in flooded chambers
* Controllable dynamically - customizable by the user
The SPRC can:
* Reduce leakage by up to 50%
* Manage a full network PRV structure
* Use the existing PRV asset - no valve replacement necessary
* Not exceed the manual pressure set point of the PRV
* Suite the UK and the EU operational requirements
* Interface with SCADA and other management tools through
standard communication port
