The growth of the number of residents in the city of Riyadh made the creation of a new transport system for drinking water into a necessity. The drinking water is produced in a combined power plant and desalination plant in Ras al-Khair (previously known as Ras al-Zour), located at the coast of the Arabian Gulf in Saudi Arabia. The distance from the city to Ras al-Khair is 460 kilometers. To create a redundant system, two parallel drinking water pipelines were constructed. The total trajectory therefore consists of 900 kilometers of pipeline, 3 pump stations, 13 water reservoirs, 360 kilometers of 13.8 kV power cables and a SCADA system. A.Hak International constructed the final segment, from pump station 3 to Riyadh including branch lines into the city. This trajectory stretches out 216 kilometers in length, which means that almost 400 kilometers . With this new transport pipeline, over 900,000 cubic meters of water can now be delivered to the city on a daily basis.
