Integrated Biological WWT & Membrane Recycle Project

The year 2006 witnessed a momentous change for airports in India with the privatization of Mumbai’s Chhatrapati Shivaji International Airport (CSIA). Being the financial capital and a key gateway of the country, expansion & modernization of CSIA holds great significance, with a vision to become one of the world’s best airports. Mumbai International Airport Limited (MIAL), a GVK Industries Ltd. led consortium, has partnered with well-known international experts for its airport design and operations. A key requirement of the development plans has been that the project be executed without disturbance to the standard airport operations & within limited timelines.

The Problem
The new Common User Terminal (CUT) is to be constructed in a phased manner. Environmental regulations have made mandatory the treatment of raw sewage before allowing it to flow into the natural ecological system. The scarcity of fresh water availability has also necessitated that sewage be treated for recycle and reuse. The treated sewage will be recycled and used for flushing, horticulture and as make up water for Cooling Towers for HVAC. A key challenge for Aquatech has been to accommodate its wastewater recycle system within the restricted space available and completion of the turnkey project within a limited time without disturbing airport operations.
