The Submersible Fresh Water Park stores fresh water in large inflatable cylinders under the sea. Due to the density difference between salt water and sweet, the cylinders are weighted to the seabed and the buoyant fresh water naturally forms an inverted droplet shape rising towards the surface. As they are unable to float, the sea surface is left undisturbed. The concept is perfectly suited to Singapore where space on both sea and land is limited, although it could be an effective solution in other coastal regions where water is limited or huge evaporation occurs. The cylinders can be detached and towed to a new location to provide aid in areas affected by natural disasters or they can be used to bolster water reserves in regions of drought.
Singapore currently buys water from neighbouring Malaysia, although annual rain fall in the city state would allow the country to be self-sufficient if the water could be effectively collected and stored. Singapore intends to increase its desalination and NEWater operations to cope with the increasing fresh water demand. These are energy-hungry solutions, and the Submersible Fresh Water Park would be an environmentally conscious and reliable alternative. The entire submersible fresh water storage system is designed to use state-of-the-art and reliable technologies, avoiding costly construction work within Singapore’s main land area, focusing on low energy consumption, and preventing the huge loss of fresh water by evaporation or discharge into the open sea due to a lack of reservoirs.
The Submersible Fresh Water Park will become an attraction and destination for Singaporeans and visitors, where they can engage with the marine environment in a way that is unique to Singapore. Above the sea surface, floating wind turbines will generate power for the necessary pumps and the electric and electronic control equipment. Maintenance boats will use the floating turbines as docking stations when required. Larger pontoons around the water park could facilitate on-site visitor attractions, which would include scuba tours, water sports, facilities for open-water swimming, dingy sailing and wind surfing. Much like an artificial reef, the new sea bed topography created by the anchors will create an ideal breeding ground for fish and corals.
