An STP plant for hotels and resorts is a critical infrastructure for managing wastewater efficiently and sustainably. With increasing water consumption, strict Pollution Control Board regulations, and rising environmental concerns, installing a sewage treatment plant for hotels has become mandatory. An advanced STP system helps hotels treat wastewater safely and reuse treated water, reducing operational costs and environmental impact.
What is an STP Plant for Hotels and Resorts?
A Sewage Treatment Plant (STP) is a wastewater treatment system designed to remove organic waste, suspended solids, oils, grease, and harmful bacteria from hotel sewage. The treated water meets regulatory standards and can be reused for non-drinking purposes such as landscaping, toilet flushing, and cleaning.
Importance of STP Plant in Hotels and Resorts
- Mandatory compliance with PCB norms
- Efficient hotel wastewater management
- Reduces dependency on fresh water
- Supports sustainable and eco-friendly hotel operations
- Enhances green hotel certification and brand value
Sources of Wastewater in Hotels and Resorts
- Guest rooms and bathrooms
- Hotel kitchens and food courts
- Laundry and housekeeping operations
- Swimming pool backwash and overflow
- Staff restrooms and utility areas
STP Treatment Process in Hotels
- Screening Chamber – Removes large solids and debris
- Equalization Tank – Maintains uniform flow and load
- Biological Treatment – Breaks down organic matter using bacteria
- Secondary Clarifier – Separates sludge and clear water
- Tertiary Treatment – Filtration and disinfection (UV/Chlorine)
- Treated Water Reuse or Safe Discharge
Best STP Technologies for Hotels and Resorts
- SBR STP Plant for Hotels – Compact, automated, cost-effective
- MBBR STP System – Ideal for variable load conditions
- MBR STP Plant – Produces high-quality reusable water
- Packaged STP Plants – Space-saving solution for hotels
Uses of Treated Wastewater in Hotels
- Garden and landscape irrigation
- Toilet flushing systems
- Cooling tower makeup water
- Floor washing and driveway cleaning
- Construction and utility applications
Benefits of Installing STP Plant for Hotels
- Saves up to 60% of fresh water consumption
- Reduces sewage discharge and environmental pollution
- Lowers water and tanker costs
- Ensures long-term legal compliance
- Improves sustainability ratings and guest confidence
STP Plant Capacity for Hotels and Resorts
The capacity of an STP plant for hotels is calculated based on:
- Number of hotel rooms and guests
- Daily water usage per room
- Laundry and kitchen wastewater load
- Future expansion plans
(Example: A 100-room hotel may require a 50–80 KLD sewage treatment plant.)
Operation and Maintenance of STP Plant
- Minimal manpower with automatic STP systems
- Routine sludge removal and equipment checks
- Regular monitoring of BOD, COD, TSS, and pH
- Low operating and maintenance cost
Conclusion
Installing an STP plant for hotels and resorts is a smart investment that ensures regulatory compliance, water conservation, and sustainable hotel operations. With advanced STP technology, hotels can reuse treated wastewater, reduce costs, and strengthen their eco-friendly brand image.
