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
