An emphasis was placed on cultural, physical, and environmental sensitivity to the site, and the Indian way of living.
Areas of Mumbai flood annually during the monsoon season and, with rising sea levels, this flooding will soon spread dramatically. Jalaashay Tower acts as a prototype for water collection and filtration. The site is dug out to act as a large water storage area which harvests and cleanses the local water. The water is filtered as it flows into the site and is then pumped to the top of the tower where it is cleansed through natural systems known as living machines.Through harvesting rainwater during the monsoon season, the residential tower is able to supply 90% of its water demands annually. At ground level, facilities (kayaks, etc.) are provided for transportation during flooding and as recreation during normal times of the year. The ground floor and living machines also act as open public space and community space for residents. Building Agenda. To design a building that will harvest and cleanse water as a precious resource that is rapidly becoming scarce in India and the world.. To create a vertical residential community bound together by a collective understanding of, and passion for, the need for water efficiency, with water efficient technologies and approaches.. To collect maximum amounts of rainwater, gray-water and flood runoff (especially during the short monsoon season) and store it for the long months of drought (the residential scheme is expected to be 90% self sufficient for water needs on an annual basis).. To manipulate the site so that the scheme becomes a ‘sink’ for the area, draining maximum water to it in times of urban flood.. To filter / cleanse the collected water using natural systems (living machines) to be used for irrigation and gray-water.. To recycle the sediments of flood runoff as well as elements from the living machines sedimentation tank, for other uses.. To integrate the elements of the scheme (predominantly the living machine ‘wetlands’ and the ground-level “collection lake”) as public-urban facilities/parks for the benefit of the community and Mumbai as a whole.. To provide facilities (e.g. kayaks) that can be used for both recreation in normal times, and emergency transport in times of urban flood (which occurs almost annually, and is likely to increase with climate change and rising sea levels).
