INTRODUCTION
Water is becoming an increasingly scare and
precious resource for drinking, irrigation
manufacture, cleaning and the maintenance of
hygiene. Sustainable water use necessitate the need
to explore and utilise alternate water source and,
wherever possible, recycle water.
Waste water can no longer be considered a ‘waste’
product to be discarded but a resource that can have
potential value if used in a ‘fit for purpose’ manner
and can be safely used for non-potable purpose such
as open space irrigation, toilet flushing and a variety
of industrial and agricultural uses. More
importantly if we reuse waste water we can conserve
high quality water for drinking and other specialised
high value uses.

INTRODUCTION CONTD..
o This presentation high light initiatives taken by
MIDC for recycle / reuse of the waste water from the
CETP, Waste water for Municipal corporation and
Minimization of the waste water to not only over come
the scarcity of the fresh water but also abatement of
pollution.

NEED FOR RECYCLING OF TREATED
WASTE WATER
Recently MoEF has issued a Moratorium for restricting the activityfor new industries and their expansion of existing industries inRatnagiri and Sindhudurg district. In Maharashtra on therecommendation of western Ghat Committee (Madhav Gadgil). Onlythose industries which will adopt cleaner technology and zeroeffluent discharge and located in the notified area are allowed.
MoEF has received revised guidelines for the Centrally SponsoredScheme of Common Effluent Treatment Plants(CETPs) in which itis clearly mentioned that CETP project cost may include zero liquiddischarge (ZLD) and related technologies. In the pattern of financialassistance (subsidy),it is clarified that central assistance (Subsidy)will be restricted to 50% of the total project cost. This shall besubject to a ceiling of Rs. 20 crore in projects without ZLD and Rs.40 crore for projects with provision of ZLD. The central fundingshall also be restricted to Rs. 1.5 crore per MLD for a CETP projectwithout ZLD. 13
NEED FOR RECYCLING OF TREATED
WASTE WATER CONTD..
State Environmental Impact Assessment Authority (SEIAA) in
Maharashtra has imposed a condition in EC (Environmental
Clearance) in respect of Waluj CETP for the providing recycling
/reusing of the treated effluent of maximum quantity.
MPCB has issued recently a circular (3/12/2011) where CETP is not
functioning satisfactory, the plot should not be given by MIDC in
these areas unless industries provide /give undertaking that they
will adopt cleaner technologies, Reuse/Recycle of treated effluent
proposal and will achieve zero liquid effluent discharge.
Reuse/recycle of effluent is helping to the industry for getting
environment clearance (EC) as there is one of the steps for no
increase of pollution load.14

CONCLUSION
In conclusions we can say Reduce waste, Recycle and / Reuse,
both reduce waste material in manufacture and waste of waste
water. Reduce by applying the Mantra of ‘3R’ (Reduce, Reuse,
Recycle) to all the manufacturing and treatment process. In other
words adopt “cleaner process” as far as possible in both
manufacturing and treatment. Recycle or Reuse after adequate
treatment either in the production process or land for irrigation.
Thus gives zero discharge effectively. There is a need of law
enforcement for Reuse, Recycle and Reduce of waste material,
however till that time self motivation can be regarded as the best
form of regulation and control. It makes the owner spend money
for setting up the required facility and operating them properly,
while at the same time the industry as well as the nation benefits
from the conservation of water and other resources. 23
