About Club Mahindra
Club Mahindra is one of India's most trusted and recognised holiday brands, operating a wide network of premium resorts across scenic destinations throughout the country. As part of the Mahindra Group, a conglomerate synonymous with quality, sustainability, and responsible business practices. Club Mahindra consistently sets high benchmarks in hospitality operations.
The Virajpet property, nestled in the lush landscapes of Kodagu (Coorg), Karnataka, serves thousands of guests annually. Given its location in an ecologically sensitive region and the resort's commitment to responsible tourism, sustainable water and wastewater management was not just a regulatory requirement it was a core operational priority.
When Club Mahindra identified the need for an efficient, compact, and environmentally compliant sewage treatment solution for their Virajpet resort, they turned to an experienced sewage treatment plant manufacturer for hotel and resort applications to deliver a system that met both performance and sustainability goals.

The Project Requirement
The Club Mahindra Virajpet resort required a full-scale sewage treatment solution that could handle daily wastewater generation from guest rooms, kitchens, laundry operations, and common facilities. Their specific requirements were:
• A compact sewage treatment plant for hotel operations capable of treating 60 KLD of mixed wastewater daily.
• High-quality treated effluent suitable for on-site reuse in landscape irrigation and toilet flushing.
• A system that operates with minimal manual intervention, reducing operational burden on resort staff.
• Compliance with KSPCB (Karnataka State Pollution Control Board) norms for treated water quality.
• A future-ready, scalable design given the resort's planned expansion.
Given these requirements, an MBR Sewage Treatment Plant (Membrane Bioreactor STP) was identified as the ideal technological fit and our team was entrusted with the complete scope.
Challenges We Faced
Every project has its share of complexities and this one was no different. Here's what we navigated on the ground:
1. Space Constraints at the Resort Site
The Virajpet resort had limited designated space for utility infrastructure. Installing a full-capacity STP plant without disrupting the guest experience required thoughtful civil layout planning and a compact equipment configuration.
2. Variable Wastewater Load
Unlike industrial effluent, hotel sewage varies significantly based on occupancy levels, seasonal tourism peaks, and operational shifts. The plant needed to handle fluctuating loads — from near-zero flow during off-season to full-capacity flow during peak holiday periods.
3. Ecologically Sensitive Location
Virajpet sits within the Coorg biodiversity belt. Any substandard treated water that entered local soil or water bodies could cause environmental damage and regulatory penalties. There was simply no room for performance failure.
4. Logistical Access for Equipment
Transporting heavy equipment to a hilly, partially remote resort location required careful coordination with local transport and civil teams — adding a layer of complexity beyond the technical scope.
Our Solution (MBR Sewage Treatment Plant)
We proposed and delivered a 60 KLD MBR Sewage Treatment Plant, a technology-forward solution that combines biological treatment with advanced membrane filtration in a single integrated process.
The MBR STP Plant was selected for several compelling reasons:
| MBR Advantage | Why It Matters for a Hotel STP |
|---|---|
| Compact footprint | Fits within limited resort utility areas |
| Superior effluent quality | Meets stringent reuse standards for gardening & flushing |
| Automated operation | Minimal manual monitoring — ideal for resort staff |
| No secondary clarifier needed | Fewer civil structures, faster installation |
| Consistent output despite variable load | Handles peak/off-peak occupancy fluctuations reliably |
| Long membrane lifespan | Low long-term maintenance cost |

The Treatment Process
Here's how the MBR STP Plant treats hotel wastewater before it's safely reused on-site:
1.SCREENING: Raw sewage first passes through a fine screen that removes large solids like rags, tissue, and food particles. This protects downstream equipment and improves process efficiency.
2.EQUALIZATION TANK: Wastewater is collected and homogenized in an equalization tank to buffer flow and load variations. This is critical for a hotel environment with uneven discharge patterns.
3.ANAEROBIC / ANOXIC ZONE: The wastewater undergoes preliminary biological treatment in an oxygen-free zone, reducing BOD load and facilitating denitrification.
4.AEROBIC MBR ZONE: The wastewater enters the aeration tank where a dense biomass of microorganisms breaks down organic matter. Hollow-fibre or flat-sheet membranes (0.04–0.4 micron pore size) separate treated water from the sludge eliminating the need for a secondary clarifier.
5.MEMBRANE FILTRATION: Ultrafiltration membranes produce consistently clear effluent, free of suspended solids, pathogens, and most dissolved organics — quality that conventional STP technology simply cannot match.
6.DISINFECTION (UV / CHLORINATION): The filtered water undergoes disinfection to eliminate any residual microbial content, producing water safe for toilet flushing and landscape irrigation.
7.TREATED WATER STORAGE & REUSE: The final treated water is stored in a dedicated reuse tank and distributed to gardening zones and flushing networks across the resort.
8.SLUDGE MANAGEMENT: Excess sludge from the biological process is periodically withdrawn, dewatered, and disposed of in compliance with local norms.
Results & Performance Outcomes
The 60 KLD MBR Sewage Treatment Plant for Club Mahindra Virajpet was successfully commissioned in 2025 and has since delivered consistent, measurable results:
| Performance Parameter | Inlet Value | Outlet Value (Post MBR) |
|---|---|---|
| BOD (Biochemical Oxygen Demand) | 200–400 mg/L | < 10 mg/L |
| COD (Chemical Oxygen Demand) | 400–800 mg/L | < 30 mg/L |
| TSS (Total Suspended Solids) | 150–300 mg/L | < 5 mg/L |
| Turbidity | High | < 1 NTU |
| Total Coliform | Present | Nil (Post UV) |
| Daily Water Reuse | — | 60 KLD (100% reuse) |
Sustainability & Water Reuse Impact
What makes this MBR STP Plant project especially significant is not just what it treats but what it gives back. In a water-stressed country like India, where hospitality facilities consume significant freshwater resources, on-site water reuse is more than a regulatory checkbox it's a genuine environmental contribution.
Every single kilolitre of treated wastewater reused for gardening or flushing at Club Mahindra Virajpet is one less kilolitre drawn from local freshwater sources. At 60 KLD capacity, the system conserves an estimated 21,900 kilolitres of water annually.
Key sustainability outcomes of this STP for resort project include:
• Zero liquid discharge no treated water is released into local water bodies or drains.
• Reduced freshwater dependency for non-potable applications (flushing, irrigation).
• Support for Club Mahindra's Green Resort initiatives and ESG reporting commitments.
• Compliance with KSPCB discharge norms protecting Coorg's ecologically rich environment.
• Reduced carbon footprint compared to transporting and treating water off-site.

Frequently Asked Questions (FAQs)
Q1. What is an MBR Sewage Treatment Plant, and why is it suitable for hotels?
An MBR (Membrane Bioreactor) Sewage Treatment Plant combines biological wastewater treatment with advanced ultrafiltration membrane technology in a single compact system. It produces consistently high-quality treated water — free from suspended solids and pathogens — that can be safely reused for toilet flushing, irrigation, and cooling. For hotels and resorts, the MBR STP Plant is ideal because it handles variable loads efficiently, requires minimal operator intervention, and occupies a smaller footprint compared to conventional systems.
Q2. How much does a sewage treatment plant for a hotel typically cost?
The cost of a sewage treatment plant for a hotel depends on factors like plant capacity (KLD), technology chosen (MBR, SBR, MBBR), site conditions, automation level, and reuse requirements. An MBR STP plant generally has a higher capital cost than conventional alternatives but offers significantly lower operational costs and superior effluent quality — making it a cost-effective long-term investment. Contact our team for a customised project estimate.
Q3. What is the typical treated water quality from an MBR STP Plant?
A well-designed MBR Sewage Treatment Plant can achieve BOD levels below 10 mg/L, TSS below 5 mg/L, turbidity under 1 NTU, and near-complete removal of total coliform after UV disinfection. This quality meets and often exceeds CPCB/KSPCB standards for treated water reuse in non-potable applications such as gardening and flushing.
Q4. Can the treated water from an STP be reused for gardening and flushing inside a resort?
Yes, when treated through a properly designed MBR STP plant with adequate disinfection (UV or chlorination), the output water meets the standards required for toilet flushing and landscape irrigation. In fact, water reuse is one of the primary motivations for installing a Sewage Treatment Plant for Hotel properties, as it significantly reduces freshwater consumption and operational utility costs.
Q5. What maintenance does an MBR Sewage Treatment Plant require?
An MBR Sewage Treatment Plant requires routine maintenance that includes membrane cleaning cycles (chemical maintenance cleaning every 2–4 weeks and recovery cleaning every 3–6 months), blower servicing, sludge wasting, and periodic inspection of sensors and control panels. With a proper AMC in place, an MBR STP Plant at a resort can operate reliably with minimal disruption to day-to-day operations.
