ABB FlowMaster flowmeters are helping Riyadh cut leakage in its water-distribution network by about 40%.
The flowmeters are being used as part of a large-scale project to modernise the vast but ageing network.
Riyadh is a sprawling city that stretches over some 536 square kilometres, an area more than five times the size of Paris. About 60% of Riyadh’s valuable water supply is lost through leakage in the 10 000 km of pipes that transport water to the city’s 4.5 million population.

The target set by the government-owned National Water Company is to reduce the volume of water and revenues lost to leakage to a more sustainable 20%. One of the most important tools to achieve this target is the 900 ABB AquaMaster and WaterMaster flowmeters that measure the flow and pressure of water in the network’s primary pipeline.
“This project required a compact, robust and maintenance-free solution that would measure pressure as well as flow, and transmit the data via the GSM telecoms network to the National Water Company’s central control room,” explained Adel Al-Sammak, ABB’s local business manager for instrumentation in Saudi Arabia.
The solution had to be exceptionally robust. For those locations where connection to the power network was not possible, battery-powered technology had to be used. Both AquaMaster and WaterMaster share the same features of accuracy, ease-of-use and advanced data communications. The former is powered by the AC network, the latter by a single ultra-long-life battery.
Their strong, durable design ensures a long maintenance-free operating life under the most difficult conditions. They can be buried directly in the ground or submersed in water without the need for costly protective chambers. Their measurement accuracy in both flow and pressure enables National Water Company to know exactly how much water is flowing through the main pipeline, and to detect leaks as and where they happen.
“ABB is proud to be playing such an important role in projects that help to reduce water losses for the capital and its six million inhabitants,” said Al-Sammak.
