## 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  (e)  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.

Water saving in industrial sector can be achieved by undertaking various measures for increasing water use efficiency. 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.
