Delhi’s ever-growing population and rapid urbanization have made effective sewage treatment a top priority for the city’s environmental future. The Delhi Pollution Control Committee (DPCC), often referred to as the Delhi Pollution Control Board, is at the forefront of this mission. In 2025, the DPCC’s updated Sewage Treatment Plant (STP) guidelines have set new benchmarks for water management, pollution control, and sustainability across the National Capital Region.
What is the Delhi Pollution Control Committee (DPCC)?
The DPCC is an autonomous regulatory authority under the Government of NCT of Delhi, operating since 1991. It is responsible for implementing and enforcing environmental laws, including the Water (Prevention and Control of Pollution) Act, 1974, and the Air (Prevention and Control of Pollution) Act, 1981. The committee works in close coordination with the Central Pollution Control Board (CPCB) and has the authority to monitor, regulate, and control pollution sources throughout Delhi.
Key Functions of DPCC:
Monitoring air, water, and noise pollution levels
Issuing environmental consents and permits for industries and infrastructure projects
Enforcing pollution control standards and taking legal action against violators
Promoting sustainable development and public awareness
Conducting research and emergency response for environmental incidents
Why is the DPCC So Important?
Delhi faces some of the most severe environmental challenges in India, including toxic air, contaminated water, and mounting waste. The DPCC’s regulatory oversight is crucial for:
Protecting Public Health:
By minimizing exposure to harmful pollutants in air and water, DPCC helps reduce disease and improve quality of life.Enabling Sustainable Urban Growth:
Strict environmental compliance ensures that Delhi’s development does not come at the cost of its natural resources.Conserving Natural Resources:
By enforcing waste and sewage treatment norms, DPCC helps preserve water bodies and groundwater.Ensuring Legal Accountability:
The DPCC holds polluters responsible, imposing fines and other penalties for non-compliance.Raising Public Awareness:
Through education campaigns and community engagement, DPCC empowers citizens to participate in pollution control.
Without the DPCC’s vigilant oversight, unchecked pollution would threaten Delhi’s future and its citizens’ well-being.
Delhi Pollution Control Board STP Guidelines 2025: What’s New?
The DPCC’s 2025 STP guidelines, aligned with the latest CPCB standards, are designed to address Delhi’s unique urban and environmental challenges. Here’s what you need to know:
Who Must Install an STP?
All new and existing residential, commercial, and institutional projects above specified thresholds must install STPs. This includes large apartment complexes, hotels, malls, hospitals, and educational campuses.
Key 2025 STP Guidelines and Parameters
| Parameter | Standard Value |
|---|---|
|
pH |
6.5 – 8.5 |
|
BOD (5th day) |
≤ 10 mg/L |
|
COD |
≤ 50 mg/L |
|
Suspended Solids |
≤ 10 mg/L |
|
Ammonical Nitrogen |
≤ 5 mg/L |
|
Total Nitrogen |
≤ 5 mg/L |
|
Fecal Coliform |
≤ 100 MPN/100 mL |
Other Key Regulations:
Mandatory Installation:
All qualifying projects must set up STPs as per DPCC norms.Technology Selection:
Only CPCB-approved, advanced technologies such as Activated Sludge Process (ASP), Membrane Bio Reactor (MBR), and Moving Bed Bio Reactor (MBBR) are allowed.Online Monitoring:
Real-time monitoring systems with inline sensors must be installed, with automated data transmission to authorities.Reuse of Treated Water:
Treated water must be reused for non-potable purposes such as toilet flushing, landscaping, and cooling towers.Safe Design & Access:
STPs should not be installed in residential basements and must be easily accessible and well-ventilated.Modular and Scalable Design:
Plants should be designed for easy expansion as sewage loads increase.
What Happens if You Don’t Comply with DPCC STP Guidelines?
Non-compliance with DPCC’s STP guidelines can have serious consequences, including:
Fines and Penalties:
Heavy financial penalties, sometimes running into lakhs of rupees, are imposed for violations.Closure Orders:
Non-compliant facilities may be shut down or have their operations suspended until compliance is achieved.Legal Action:
Persistent offenders can face prosecution under environmental laws, with cases often referred to the National Green Tribunal (NGT).Reputational Damage:
Public disclosure of violations can harm an organization’s reputation and stakeholder trust.Environmental Compensation:
Operators may be required to pay for environmental damage caused by untreated or poorly treated effluent.
