Hotels are among the highest water-consuming commercial establishments. From guest rooms, kitchens, laundries, swimming pools, and landscaping to staff facilities, a hotel generates a large volume of wastewater every day. Managing this sewage efficiently is not only an environmental responsibility but also a legal requirement in India.
This is why installing a Sewage Treatment Plant (STP) for hotels has become mandatory across most states. One of the most frequently asked questions by hotel owners, builders, and facility managers is:
“What is the STP plant cost for a hotel in India?”
In this detailed guide, we explain hotel STP plant cost, capacity calculation, technology options, operating expenses, benefits, and how to choose the right manufacturer.
What Is an STP Plant for Hotels?
A Sewage Treatment Plant (STP) is a system designed to treat wastewater generated from hotel operations such as:
- Guest room toilets and bathrooms
- Kitchen and dishwashing areas
- Laundry units
- Staff washrooms
- Housekeeping and cleaning activities
The treated water meets CPCB/SPCB discharge norms and can be reused for non-potable applications like:
- Toilet flushing
- Gardening and landscaping
- Cooling towers
- Floor washing
For hotels, an STP helps reduce freshwater consumption, control operational costs, and maintain environmental compliance.
Is STP Mandatory for Hotels in India?
Yes. As per Central Pollution Control Board (CPCB) and respective State Pollution Control Board (SPCB) guidelines, hotels generating wastewater above prescribed limits must install an STP.
STP is mandatory for:
- Budget hotels
- Luxury hotels
- Resorts
- Banquet halls
- Hospitality complexes
Failure to comply may result in:
- Penalties and notices
- Refusal of Consent to Operate (CTO)
- Legal action or closure
Hence, installing an STP is not optional—it is a regulatory necessity.
STP Plant Cost for Hotel in India (Capacity-Wise)
The cost of an STP plant for a hotel mainly depends on wastewater generation, which is directly linked to the number of rooms, occupancy rate, and facilities.
Approximate Hotel STP Cost in India
| STP Capacity | Hotel Size (Approx.) | STP Plant Cost (INR) |
|---|---|---|
| 10 KLD | 10–15 rooms | ₹3 – ₹5 lakhs |
| 20 KLD | 20–30 rooms | ₹4.5 – ₹7 lakhs |
| 30 KLD | 35–45 rooms | ₹6 – ₹9 lakhs |
| 50 KLD | 60–80 rooms | ₹9 – ₹14 lakhs |
| 100 KLD | 120–150 rooms | ₹15 – ₹25 lakhs |
| 200 KLD | Large hotels & resorts | ₹28 – ₹45 lakhs |
| 500 KLD | Luxury resorts | ₹65 lakhs – ₹1.2 crore |
Note: These are indicative prices. Actual STP plant cost for hotels may vary depending on technology, reuse standards, automation, and site conditions.
How Is STP Capacity Calculated for a Hotel?
Correct STP sizing is crucial to avoid underperformance or overinvestment.
Common Calculation Method:
- Wastewater generation:
80–90% of total water consumption - Average water consumption:
180–250 liters per guest per day (LPD)
Example:
A 50-room hotel with 2 guests per room:
50 × 2 × 200 LPD = 20,000 liters/day ≈ 20 KLD STP
Additional capacity may be added for kitchens, laundry, and future expansion.
Factors Affecting STP Plant Cost for Hotels
Several technical and commercial factors influence the total cost of an STP for hotels.
1. STP Technology Selection
Different technologies have different capital and operating costs:
- MBBR (Moving Bed Biofilm Reactor)
Most preferred for hotels due to compact design and low maintenance - SBR (Sequencing Batch Reactor)
High treatment efficiency, suitable for medium to large hotels - MBR (Membrane Bioreactor)
Produces very high-quality treated water, higher cost - ASP (Activated Sludge Process)
Traditional method, requires more space and manpower
2. Quality of Treated Water Required
Hotels often reuse treated water for flushing and landscaping. This may require:
- Pressure Sand Filter (PSF)
- Activated Carbon Filter (ACF)
- UV or chlorination system
Higher reuse standards = higher cost.
3. Civil Construction vs Package STP
- RCC civil STP: Higher civil cost, longer construction time
- Prefabricated / package STP: Compact, faster installation, lower lifecycle cost
Most hotels prefer compact package STPs to save space.
4. Automation Level
- Manual operation – lower cost, higher manpower
- Semi-automatic – balanced approach
- Fully automatic (PLC based) – higher initial cost, minimal manpower
5. Pollution Control Compliance
SPCB consent conditions may demand advanced treatment stages, impacting project cost.
Operating Cost of STP Plant for Hotels
Besides capital investment, hotels must consider monthly operating costs.
Typical Operating Cost Includes:
- Electricity (blowers, pumps)
- Chemicals (if required)
- Operator salary
- Sludge disposal
- Routine maintenance
Average OPEX:
₹3 – ₹8 per KL of wastewater treated
Energy-efficient STP designs help hotels keep operational expenses low.
Benefits of Installing STP in Hotels
Installing a sewage treatment plant provides multiple long-term advantages.
Key Benefits:
- 40–60% reduction in freshwater usage
- Lower water and tanker costs
- Compliance with environmental laws
- Improved brand image & sustainability rating
- Eligibility for green building certifications
- Reliable wastewater management during peak occupancy
Best STP Technology for Hotels
For most hotels in India, MBBR-based STP plants are considered the best choice due to:
- Compact footprint
- Stable performance under load variations
- Low maintenance
- Cost-effective installation
- CPCB/SPCB compliance
Luxury hotels and resorts may opt for MBR systems for superior water quality and reuse.
