Jumeirah Islands in Dubai will have a 23:77 water-to-land ratio, making it a one-of-a-kind real estate project. The ratio is said to be the highest in the world for a project of this scale. The development is also the first in the world where man-made islands have been created in the desert with seawater pumped in to form a natural beach-like environment. Developer Nakheel said that work on the lakes and canals was progressing as per schedule. Using cutting-edge engineering technology, Nakheel has already completed the work of filling of the artificial lakes with seawater that is pumped in from the Gulf, using advanced pumping and water circulation techniques. The underground pipeline is the main source of water for the development that comprises 46 clusters of islands spread across an area of 300 hectares. It brings in 400 litres of water per second. Advanced technology ensures that fresh seawater is brought into the canals to control salinity. The canal water is flushed out by gravity back into the sea through a discharge chamber at the edge of the canal. The extensive network of artificial lakes, canals and bridges is now ready, setting the stage for the full-scale development of the project. The landscaping in the common areas and around the villas, is underway. Some 60% of the construction work on villas is complete and the first of the villas would be ready for occupation in May 2005. Sultan bin Sulayem, Nakheel chairman said: “We have used the world’s best expertise to ensure that this exclusive enclave offers an out-of-this-world experience to its residents, with a focus on waterfront living that replicates the ambience associated with natural seawater.” “Jumeirah Islands professes the highest water-to-land ratio in a development surrounded by dynamic water flows as compared to any other project in the world. Out of the total area of 300 hectares, 68 hectares, or nearly 23% of the project is filled with water that flows constantly ensuring clean water around the clusters throughout.” Water circulation across the extensive network of lakes and canals is maintained through two huge pump stations. One of the pump stations transfers water at the rate of 2000 l/s from canal level 3.5 m to canal level 11m. The other transfers water at the rate of 600 l/s from canal level 3 m to canal level 7 m. All canals are lined using 1 mm high-density polyethylene (HDPE) liner. “The pump stations maintain constant circulation in the canals and create waterfalls at designated locations. Further, a network of gravity transfer lines, equaliser connections and re-circulation pumps are incorporated into the system to ensure there are no dead pockets in the canals. This means there is no stagnant water at any of the places,” said bin Sulayem.
