ETP Adequacy
Effluent Treatment Plant capacity, unit design and retention time assessed against the measured effluent load.
Adequacy Certificate & Report
GPCB-authorised auditors
Certification that your ETP, STP and air pollution-control systems are adequately sized for the actual pollution load — a capacity-vs-load assessment prepared by GPCB-authorised auditors for consent, expansion and bank requirements.
Aura Environmental Services Pvt. Ltd. prepares ETP, STP and Air Pollution Control (APC) adequacy certificates and reports as GPCB-authorised Schedule-II auditors in Odhav, Ahmedabad. We characterise the actual effluent and emission load using our NABL lab, review the design capacity and each treatment unit, assess adequacy against the discharge and emission norms, and issue a certified adequacy report — with clear augmentation recommendations where a system falls short — for GPCB consent, capacity expansion, consent renewals and financial-institution requirements.

What we certify
Adequacy, proven against the real load
Every certificate is grounded in measured load and a unit-by-unit review of the plant.
STP Adequacy
Sewage Treatment Plant sizing and treatment stages assessed against occupancy and sewage generation.
Air Pollution Control (APC)
Scrubbers, bag-filters, cyclones and stacks assessed against the actual emission load and norms.
Capacity vs. Load Assessment
Hydraulic and organic load compared to design capacity, unit by unit, to find any bottleneck.
Expansion & Augmentation
Adequacy for a proposed production increase, with augmentation recommendations where needed.
Certification for Consent & Banks
A signed adequacy certificate for GPCB consent, renewals, CETP membership and financial institutions.
What we assess
The parameters behind an adequacy call
We compare the measured load and treatment performance against design — the basis of a defensible adequacy certificate.

How it works
From load data to signed certificate in four steps
A clear, accountable process — so you always know what happens next.
01
Measure the load
We sample and analyse influent, effluent and emissions in our NABL lab to establish the real load.
02
Review the plant
We assess design capacity and each treatment unit — flows, retention time, loading and performance.
03
Assess adequacy
Measured load is compared to design and norms to determine whether each unit is adequate.
04
Certify & recommend
You receive a signed adequacy report — with augmentation recommendations where a system falls short.

Answers
Adequacy certificate FAQs
What is an ETP/STP adequacy certificate?
It is a certified assessment confirming that your treatment plant is adequately designed and sized to treat the actual pollution load and consistently meet the prescribed discharge or emission norms. It is prepared after measuring the real load and reviewing each treatment unit.
When do I need an adequacy report?
Commonly for GPCB consent (CTE/CTO) and renewals, when expanding or enhancing production, for CETP membership, and when banks or financial institutions require proof that your pollution-control systems are adequate.
What happens if my plant is found inadequate?
We identify the specific units that are under-capacity and provide clear augmentation recommendations — additional capacity, unit upgrades or process changes — so you can bring the system up to the required standard.
Do you test the effluent as part of the assessment?
Yes. We characterise the influent, effluent and emissions in our NABL-accredited laboratory so the adequacy call is based on your plant's real, measured load — not assumptions.
Can you also upgrade the ETP if it's inadequate?
Yes. Through our engineering services we can design and augment ETP/STP and air pollution-control systems — so assessment and remedy come from one partner.
