Description
Introduction
Hospitals play a vital role in public health, but they also produce large volumes of wastewater containing harmful contaminants, chemicals, and pathogens. This hospital wastewater, if released untreated, can pose serious threats to the environment and public health. Therefore, every hospital—big or small—must install a Sewage Treatment Plant (STP) to properly treat and disinfect the sewage before it is discharged or reused.
A Sewage Treatment Plant for hospitals ensures that the wastewater generated from toilets, laboratories, operation theaters, laundry, and kitchens is treated according to CPCB (Central Pollution Control Board) norms. It not only helps in pollution control but also supports water reuse, sustainability, and compliance with environmental laws.
V AQUA WATER TREATMENT COMPANY, a trusted name in India’s water and wastewater treatment industry, offers custom-built, CPCB-approved STP systems for hospitals across Pan India—designed to meet the highest hygiene, safety, and environmental standards.
What Is a Sewage Treatment Plant (STP Plant)?
A Sewage Treatment Plant (STP) is a system that removes contaminants from wastewater using physical, biological, and chemical processes. In hospitals, STPs are designed with additional disinfection mechanisms to eliminate pathogens and toxic substances before discharge.
Key Objectives of an STP in Hospitals:
- Treat and disinfect hospital sewage before discharge.
- Remove biological and chemical contaminants.
- Prevent pollution of water bodies and soil.
- Ensure compliance with CPCB and Bio-Medical Waste Management Rules, 2016.
- Promote sustainability through treated water reuse.
Unlike domestic sewage, hospital wastewater contains antibiotics, disinfectants, radioactive isotopes, and pathogenic organisms, making it more hazardous. Thus, hospital STPs must include advanced treatment and sterilization stages to ensure public and environmental safety.
STP Plant Diagram (Process Flow Overview)
While a visual diagram best explains the STP system, below is a step-by-step process flow describing how a hospital sewage treatment plant operates:
- Collection Chamber: Wastewater from toilets, wards, kitchens, and labs is collected through underground pipes.
- Screen Chamber: Large debris like plastics, gauze, cotton, and tissues are removed.
- Equalization Tank: Balances flow variations and maintains uniform loading.
- Aeration Tank: Air blowers supply oxygen to microorganisms that decompose organic waste.
- Secondary Clarifier: Settles the biomass (sludge) formed during biological treatment.
- Tertiary Treatment Unit: Includes filtration (sand, carbon, and UF) and advanced disinfection (UV or chlorination).
- Sludge Handling Unit: Sludge is dewatered and safely disposed of as per biomedical waste norms.
- Treated Water Tank: Stores clean, odor-free, reusable water for gardening or flushing.
This process ensures complete treatment and sterilization of hospital wastewater before reuse or disposal.
Sewage Treatment Plant Legal Requirements for Hospitals in India
Hospitals must comply with several national environmental and pollution control laws to operate an STP system. Non-compliance can lead to penalties and even suspension of hospital operations.
Regulatory Bodies:
- Central Pollution Control Board (CPCB)
- State Pollution Control Boards (SPCBs)
- National Green Tribunal (NGT)
- Ministry of Environment, Forest and Climate Change (MoEFCC)
Legal Requirements:
-
Hospitals generating more than 10 KLD (10,000 liters/day) of sewage must install an STP.
-
Hospitals must obtain:
-
Consent to Establish (CTE) – before construction.
-
Consent to Operate (CTO) – after installation and testing.
-
-
STP must ensure treated water meets CPCB discharge norms.
-
Treated water reuse for flushing, gardening, and HVAC is encouraged.
-
Sludge disposal must comply with Biomedical Waste Management Rules.
CPCB Effluent Standards for Hospitals:
| Parameter | Permissible Limit |
|---|---|
| pH | 6.5 – 8.5 |
| BOD (mg/L) | ≤10 |
| COD (mg/L) | ≤50 |
| TSS (mg/L) | ≤10 |
| Fecal Coliform | ≤100 MPN/100 ml |
V AQUA WATER TREATMENT COMPANY designs and installs CPCB and NABH-compliant STPs for hospitals, ensuring complete adherence to all environmental and safety guidelines.
Sewage Treatment Plant Guidelines for Hospitals
1. Design and Planning Guidelines:
- STP capacity must match hospital wastewater generation (based on beds, patients, and staff).
- Separate drains should collect sewage and biomedical effluent.
- Tanks should be made of corrosion-resistant materials (RCC or FRP).
- Include odor control systems, sludge drying units, and automated monitoring.
- Treated water must be disinfected before reuse or disposal.
2. Operational Guidelines:
- Maintain pH and chlorine levels in treated water.
- Periodically test effluent quality at NABL-accredited labs.
- Store and dispose sludge safely as per CPCB norms.
- Operators must be trained and certified.
- AMC (Annual Maintenance Contract) should be in place.
3. Maintenance Guidelines:
- Regular cleaning of screens, aeration diffusers, and filters.
- Periodic calibration of pumps, blowers, and sensors.
- Scheduled inspection by pollution control authorities.
V AQUA offers AMC, operator training, and 24/7 service to ensure continuous, compliant, and efficient STP operation in hospitals.
What Is the Cost of an STP Plant for Hospitals?
The cost of a hospital STP plant depends on its capacity, design, automation level, and technology.
| STP Capacity (KLD) | Hospital Size | Approximate Cost (INR) |
|---|---|---|
| 5–20 KLD | Small clinics or nursing homes | ₹3–₹6 Lakhs |
| 20–50 KLD | Medium-sized hospitals | ₹7–₹12 Lakhs |
| 50–100 KLD | Large multi-specialty hospitals | ₹12–₹25 Lakhs |
| 100–500 KLD | Super-specialty or government hospitals | ₹25–₹60 Lakhs+ |
Cost-Determining Factors:
- Technology Used: MBBR, SBR, MBR, or FAB systems.
- Automation Level: Manual, semi-automatic, or fully automatic.
- Construction Material: RCC vs. FRP tanks.
- Wastewater Load and Type: Hospital sewage includes chemical and biological wastes.
- AMC and service requirements.
V AQUA WATER TREATMENT COMPANY provides affordable, durable, and customized STP systems for hospitals, designed to ensure the lowest operational cost and maximum treatment efficiency.
STP Plant Process in Hospitals (Step-by-Step)
1. Preliminary Treatment
Removes large solids, plastics, bandages, and other debris using bar screens and grit chambers.
2. Primary Treatment
Settles suspended solids in sedimentation tanks to separate sludge and floating matter.
3. Biological Treatment
Uses microorganisms to decompose organic matter in aeration tanks with continuous oxygen supply.
4. Secondary Clarification
The treated sewage is separated from biological sludge using clarifiers.
5. Tertiary Treatment
This includes sand and carbon filtration, followed by UV or chlorination disinfection to remove pathogens and residual contaminants.
6. Sludge Management
Sludge is thickened, dewatered, and dried before being disposed of as per biomedical norms.
7. Treated Water Reuse
The purified water can be safely reused for gardening, HVAC cooling, and toilet flushing within the hospital premises.
This multistage process ensures zero discharge and supports hospitals in maintaining hygiene and sustainability standards.
