OBJECTIVES OF

Water flow System DESIGN

To provide continuous and healthy PHE & utility services. like

Raw Water treatment

Plumbing & Fire

Water For Utility

Waste Water Treatment

Rain Water Recharge

To protect the public health & Environment (i.e. save water,

Recharge Ground water & Stop polluting water resource & earth

due to Effluent water To Provide Easily & Simply statutory approvals from authority.


4/10

Source of RAW water For

Industrial area

From City Water Supply (Local authority will provide)

From Ground Water (Need Bore Permission with Rain waterrecharge calculation & water flow scheme )

Recycled water ( Reuse of effluent/Sewage treated water for

irrigation & Process water i.e.- make-up for cooling tower,boiler etc.) Except Human use and Ground water recharge

C.G.W.A. Guidelines

for withdrawal of Ground water

C A T E G O R Y

- NOTIFIED AREA

Permission to withdrawal Ground water through any pumping system

will not be accept for any purpose other than drinking water.

- NON-NOTIFIED AREA

NOC for Ground Water withdrawal will be considered forIndustries/Infrastructure projects which are either NEW or under

EXPANSION as per the C.G.W.A. given guideline :

CATEGORY RECYCLE/REUSEGRAUND WARER WITHDRAWAL ANDGROUND WATER RECHARGE

SAFEMandatory recycling and reuse of

water

quantity of ground water exceeds 100cu.mtr/day.

Rain water harvesting to be adopted.

SEMI-

CRITICAL

Major and Medium industriesshall recycle and reuse at least

50% of the waste water

The withdrawal should not exceed 200% of the

recharge quantity.

CRITICALMajor and Medium industries

should fully recycle and reuse the

waste water

Withdrawal should not exceed 100% of the

recharge quantity.

OVER-

EXPLOITED

Efficient utilization of recycled

water and reuse of water should

be mandatory

The withdrawal should not exceed 50% of the

recharged quantity.

No permission for industries like packaged,

drinking, mineral water, distilleries, breweries,

soft drink manufacturing, textiles, paper and pulp

etc.
