## ANSWER

## THE MINISTER OF STATE FOR WATER RESOURCES, RIVER DEVELOPMENT AND GANGA REJUVENATION

(DR. SANJEEV KUMAR BALYAN)

(a) The National Commission for Integrated Water Resources Development (NCIWRD) in its Report (1999) has estimated that the annual water requirement for industries would be about 37 Billion Cubic Meters (BCM) and 67 BCM for the years 2010 and 2025 respectively.

(b) to   (d) A recent study undertaken by Confederation of Indian Industries - Triveni Water Institute  (CII-TWI)  for  industries  such  as  Integrated  Steel  Plants,  Pulp  &  Paper,  Agro  based industries,  Textiles,  Thermal  Power,  Fertilizer  and  Sugar  has  shown  immense  potential  for water savings. Their study indicates that around 10 BCM of fresh water can be saved each year by  adopting  measures  such  as  improving  Cycles  of  Concentration  in  Cooling  systems,  water pressure  management,  leak  control,  efficient  fixtures  and  faucets,  and  rain  water  harvesting, wastewater recycling and reuse, measurement and controls through digital online instrumentation and proper landscaping.

Central  Water  Commission  and  Central  Ground  Water  Board  have  prepared  the  "General Guidelines for Water Audit & Water Conservation" in December, 2005 as conceptual guidelines to  cover  broadly  three  main  sectors  of  water  use  viz.  irrigation,  domestic  and  industrial.  The aims and objectives of these guidelines are to introduce, standardize and popularize the water audit  system  for  conservation  of  water  in  all  sectors  of  water  use  and  improve  the  water  use efficiency.  These  guidelines  were  circulated  among  all  the  State  Governments  for  facilitating formulation of their own region specific, project specific, system specific and service specific guidelines. Central Water Commission has also prepared "Guidelines for Improving Water Use Efficiency in Irrigation, Domestic & Industrial Sectors", 2014.

The National Water Policy, 2012 (NWP) has recommended that industries in water short regions may be allowed to either withdraw only the makeup water or should have an obligation to return treated effluent to a specified standard back  to the hydrologic system. Tendencies  to unnecessarily  use  more  water  within  the  plant  to  avoid  treatment  or  to  pollute  ground  water need to be prevented. NWP also states that subsidies and incentives should be implemented to encourage  recovery  of  industrial  pollutants  and  recycling/reuse,  which  are  otherwise  capital intensive.
