The sprawling city of Riyadh’s stretches over 130,000 acres, an area more than five times the size of Paris. In the past, about 60 percent of Riyadh’s water supply disappeared through leakage in the 6000 miles of piping that transported water to the city’s 4.5 million population. The government-owned National Water Company set out to reduce the volume of water and revenues lost to leakage to a more sustainable 20 percent.
ABB FlowMaster flowmeters
The company required a compact, robust and maintenance-free solution as part of a large-scale project to modernize Riyadh’s vast but aging water distribution network. The solution would transmit measured data via a GSM telecommunications network to the National Water Company’s central control room.
On three separate occasions company engineers selected ABB WaterMaster
flowmeters to play a prominent role in the solution. They repeatedly selected these flowmeters for their outstanding accuracy and performance.
Requirements called for an exceptionally robust solution. For those locations where no power was available, the flowmeters had to be battery-powered to avoid the high maintenance associated with miniature solar panels. Currently about 900 of these ABB flowmeters measure water flow rates to help achieve the leakage target.
