This project will be built at Riyadh in Saud Arabia. The work will involve the design, supply and installation of pipelines with a diameter of 1,200mm, establishment of hydraulics system and remote control systems for the water reuse lines in Saudi Arabia's capital city. One of the main challenges is water scarcity. In order to overcome water scarcity, substantial investments have been undertaken in seawater desalination, water distribution, sewerage and wastewater treatment. Today about 50% of drinking water comes from desalination, 40% from the mining of non-renewable groundwater and only 10% from surface water in the mountainous southwest of the country. The capital Riyadh, located in the heart of the country, is supplied with desalinated water pumped from the Persian Gulf over a distance of 467 km. Water is provided almost for free to residential users.
