STP ETP Audits
STP / ETP Audits
What are STP and ETP Audits?
STP (Sewage Treatment Plant) Audits and ETP (Effluent Treatment Plant) Audits are systematic evaluations of wastewater treatment facilities to ensure that they are designed, operated, and maintained in compliance with Pollution Control Board (SPCB) norms, CPCB guidelines, and environmental regulations.
These audits check whether your treated water meets prescribed discharge standards and whether your plant is running at optimum efficiency, thereby protecting the environment and avoiding legal penalties.
Why Do You Need an STP/ETP Audit Report?
Regular audits are essential for industries, residential complexes, and commercial facilities generating sewage or industrial effluents. A professional audit helps you:
- Ensure compliance with SPCB/CPCB discharge norms
- Avoid show-cause notices, penalties, and legal action
- Identify performance gaps in STP/ETP operations
- Optimize operation and maintenance costs
- Improve treatment efficiency and water reuse potential
- Demonstrate commitment to sustainability and ESG goals
Who Requires STP & ETP Audits?
STP/ETP audits are applicable for:
- Industries (pharmaceutical, textile, chemical, food processing, metal, etc.)
- Commercial establishments (IT parks, malls, hotels, hospitals, institutions)
- Housing societies and real estate projects with sewage treatment plants
- Infrastructure projects under environmental clearance conditions
Scope of STP/ETP Audit
A typical STP/ETP audit includes:
- Evaluation of plant design, capacity, and adequacy
- Assessment of inlet and outlet water quality against prescribed standards
- Performance check of primary, secondary, and tertiary treatment units
- Review of operation & maintenance (O&M) practices
- Verification of logbooks, records, and compliance documents
- Recommendations for improving efficiency and compliance
- Guidance on treated water reuse (gardening, flushing, industrial process use)
Timeline & Frequency
- Audit Time: 7–15 days (depending on plant size & complexity)
- Frequency: At least once a year or as mandated by SPCB/CPCB or environmental clearance conditions

FAQ: Frequently asked questions
It is a detailed evaluation of a Sewage Treatment Plant or Effluent Treatment Plant to ensure compliance with environmental standards and Pollution Control Board regulations.
Industries, housing societies, hospitals, commercial complexes, and infrastructure projects with wastewater treatment facilities.
At least once every year, or more frequently if mandated by SPCB/CPCB or environmental clearance conditions.
We provide corrective recommendations. Non-compliance, if not addressed, may lead to penalties, show-cause notices, or closure orders from SPCB.
Yes. Based on the audit report, treated water can be recommended for reuse in gardening, flushing, cooling towers, or industrial processes, reducing freshwater dependency.
We handle sampling, testing, performance evaluation, documentation, and compliance advisory, ensuring your plant runs efficiently and meets all legal standards.
