Emirates, Qatar, Bahrain, Oman), vacuum sewer systems become more and more important due to easy and fast installation along with water saving effects and easiness of maintenance. Palm Island Jumeirah, located at the coast of Dubai City, United Arab Emirates, has low, flat terrain, with a high water table, a water protection area, a need to conserve freshwater, and a low population density. It has therefore installed a vacuum sewer system. Approx. 23,000 people (or 2000 buildings) will be connected to this vacuum sewer system. The system has only one central vacuum station serving 40 km of sewer line. The vacuum station is considered to be the biggest vacuum station in the world. The eco-city of Masdar, U.A.E., uses a vacuum sewer system as well to separate grey from black water. Lately, vacuum sewer systems become popular for industrial and commercial projects as well, where only little domestic waste water occurs and where the flexibility of a vacuum sewer system allows easy coordination with usually plenty of other utilities in the ground. Good examples can be found again in the Middle East, such as some small industrial areas in the Emirate of Ras al Khaimah or the newly built Qatalum Aluminium Plant in Qatar, the world's largest primary aluminium plant. Vacuum sewer systems are not only used in the Europe or Middle East but even in low developed third world countries. Several vacuum sewer systems have been already built or are currently under construction in Africa (South Africa, Botswana, Namibia) for townships and rural areas where the benefit of fast construction time, cost saving trenching and high flexibility have come to full effect. Australia has been one of the largest users of vacuum sewer systems due to the low installation and operational costs. The largest system to-date has been at the Tea Gardens development in New South Wales, which will ultimately handle over 4,500 houses. The Water Corporation in Western Australia is considered the largest single owner of vacuum systems in the world with over 30 schemes now under their operational control. High water table areas The United Kingdom is well served by vacuum sewerage systems. The region most extensively served is the low lying fenlands of the East of England. High water tables (in some cases less than 1 metre below the surface) and poor ground conditions have meant that the local water company, Anglian Water, has embraced the
