At the present time one third of the world’s population lives in water scarce areas. By the year 2050 it is estimated that the proportion of people living in moderate water stress conditions will increase to two thirds and a half of the population will be living under severe water stress conditions. The wisewater management is a new concept to provide water supply and sanitation services in arid and semi arid rural areas that was developed following WHO recommendations for the safe reuse of water. It was conceived in Madhya Pradesh (MP), a central state of India that has a high rural population with limited access to water and sanitation. The greywater reuse system which is part of wisewater management collect, treat and reuse bathroom water (shower and non toilet/black water) for recycling and flushing of toilets. The purpose of Manual is to establish acceptable means for greywater reuse as a guide for local government and residential schools, setting minimum standards for design, installation and maintenance and preparation and execution of water safety plans for minimizing health risks associated with greywater reuse. The Manual demonstrates methodology proposed by WHO to derive the health based targets and water safety plan for safe (re)use of greywater. Greywater reuse systems can be designed and implemented in the institutions anywhere in the world using the Manual.

dear Pawan
i want to provide a water recycling system for shower water and laudry water for tiolets. i want a compact system for a worker camp of 700 workers.
can u help.
All of these grey water re-use system developed in Madhya Pradesh during 2005-2009 failed, which one can witness them in field. Some time it seems that professionals in water sector with research background don’t even fair in understanding social and economic factors in the region and that leads to such a situation. I feel that institutions like NEERI should adopt more pragmatic approach in its projects and affiliations.
