CGWA Groundwater NOC · Chemical Industry
CGWA Groundwater NOC for Chemical Plants
A chemical unit drawing process, cooling or boiler water from borewells needs a groundwater abstraction NOC from the Central Ground Water Authority, and the hydrogeological case behind it is scrutinised as closely as the EIA.

What this means for chemical industry
Groundwater abstraction for industrial use requires a No Objection Certificate from the CGWA, applied for through its online portal, and the decision turns on the categorisation of the assessment unit the plant sits in: safe, semi-critical, critical or over-exploited. For a chemical unit the demand is rarely small: process water, cooling tower makeup, boiler feed, DM plant regeneration and scrubber water together produce a figure that has to be justified rather than merely stated. The complication specific to this sector is that the same water reappears on the other side of the balance as effluent, so the abstraction figure in the NOC application, the water balance in the EIA and the consented effluent volume in the MPCB consent all have to be the same set of numbers. Regulators read them together.
How KIPL runs it
KIPL builds the application on a hydrogeological assessment of the actual site (aquifer characteristics, existing abstraction in the vicinity, water-level behaviour) and on a water balance that shows genuine reduction before it shows abstraction: cooling cycles of concentration, condensate recovery, treated effluent reuse where the consent permits, and recharge structures sized against the site's own catchment and rainfall. What goes wrong otherwise is an application that asks for the design figure with no demand-side case behind it, in a block where the categorisation makes that difficult to grant. And a plant that finds its water permission is the constraint on the capacity its clearance already allows.
- CGWA
Abstraction requires an NOC
Industrial groundwater withdrawal needs a No Objection Certificate from the Central Ground Water Authority, applied for online, with conditions and a water conservation fee attached to the grant.
- Block category
The assessment unit decides the odds
Whether the unit is classified safe, semi-critical, critical or over-exploited governs how much abstraction can be permitted and what recharge and reduction commitments come with it.
- One water balance
It has to match the EC and the consent
The abstraction sought, the EIA water balance and the consented effluent volume are read against each other, so a divergence in any one of them is a query in all three files.

Questions from chemical industry
What chemical industry ask before appointing us.
Answered against the regulation as it stands, not as a sales pitch. If your situation is not here, ask us directly.
Ask a question →Does every chemical plant need a CGWA NOC?
Every plant that abstracts groundwater does, unless it is served entirely by an industrial water supply such as MIDC's. Units drawing borewell water for process, cooling or boiler use require the NOC, and the requirement applies irrespective of whether the plant also holds an Environment Clearance.
What if we are in an over-exploited block?
Abstraction is far more constrained and, for some uses, may not be permitted at the volume sought. The realistic route is to reduce the demand that has to be met from groundwater (higher cycles of concentration, condensate and treated-water reuse, and an alternate supply for part of the load) and to bring firm recharge commitments with the application.
How does the NOC relate to our Environment Clearance?
They describe the same water. The abstraction figure in the NOC, the water balance in the EIA and the consented effluent volume have to be mutually consistent, because inconsistency between them is visible to each authority and raises the question of which figure is real.
Can treated effluent count towards our water demand?
Reuse reduces fresh water demand and strengthens the application, provided it is permitted by the consent for the use proposed and the quality supports it. Cooling makeup and green belt irrigation are the common reuse routes; the volumes claimed should come from the treatment plant's actual recovery, not from its design figure.
What conditions come with the NOC?
Typically metering of abstraction, periodic water-level monitoring and reporting, recharge structures to be constructed and maintained, and payment of the water conservation fee where applicable. These are recurring obligations, so they belong in the plant's compliance calendar alongside consent and clearance conditions.
How long does the NOC take?
It depends on the block categorisation, the completeness of the hydrogeological report and the query cycle on the portal. The part within the applicant's control is the quality of the demand justification and the hydrogeological assessment, which is where most avoidable rounds of queries originate.
