ETP Adequacy
Effluent and Sewage Treatment Plant capacity, unit design and retention time assessed against the measured load.
Adequacy assessment at a glance
Certification that your ETP, STP and Air Pollution Control Measures are adequately sized for the actual pollution load — a capacity-vs-load assessment prepared by GPCB-authorised Schedule-I & II auditors for consent, expansion and bank requirements.
Aura Environmental Services Pvt. Ltd. prepares ETP, STP and Air Pollution Control Measures (APCM) adequacy certificates and reports from Odhav, Ahmedabad. As GPCB-authorised Schedule-II auditors we characterise the actual effluent and emission load using our NABL lab, review the design capacity and each treatment unit, and assess adequacy against the discharge and emission norms. The adequacy certificate itself is issued in collaboration with a Schedule-I auditor, as required — giving you a single accountable partner for GPCB consent, capacity expansion, consent renewals and financial-institution requirements.

Every certificate is grounded in measured load and a unit-by-unit review of the plant.
Effluent and Sewage Treatment Plant capacity, unit design and retention time assessed against the measured load.
Air Pollution Control Measures — scrubbers, bag-filters, cyclones and stacks — assessed against the actual emission load and norms.
Hydraulic and organic load compared to design capacity, unit by unit, to find any bottleneck.
Certification that a proposed change in product mix or capacity causes no increase in the effluent and emission load.
A signed adequacy certificate for GPCB consent, renewals, CETP membership and financial institutions.
We compare the measured load and treatment performance against design — the basis of a defensible adequacy certificate.

We sample and analyse influent, effluent and emissions in our NABL lab to establish the real load.
We assess design capacity and each treatment unit — flows, retention time, loading and performance.
Measured load is compared to design and norms to determine whether each unit is adequate.
You receive a signed adequacy report — with augmentation recommendations where a system falls short.
