Sewage Treatment Plant For Hotels
Many hotels today are not connected to a main municipal sewerage system, which makes installing a dedicated Sewage Treatment Plant (STP) essential rather than optional. Hotels generate a significant volume of wastewater daily from guest rooms, kitchens, laundries, and restrooms. A sewage treatment plant — also called a wastewater treatment plant or water pollution control plant — removes most pollutants from this wastewater within a few hours, before it is safely released into the environment or reused on-site.
Proper treatment isn’t just about environmental compliance — it’s essential for maintaining hygiene standards, protecting your hotel’s brand reputation, and supporting long-term sustainability goals.
Unistar Aquatech Private Limited specializes in providing reliable, customized Sewage Treatment Plants for Hotels that meet the specific needs of the hospitality industry — from small boutique properties to large resorts.
Why Do Hotels Need a Sewage Treatment Plant?
The main purpose of an STP for hotels is to treat wastewater influent so that it does not pose a health risk to guests, staff, or the surrounding environment. Wastewater from a hotel is collected and passed through several treatment stages using drains and collectors before it is clean enough to be safely discharged or reused.
Effective sewage treatment plants for small, medium, and large hotels and resorts are compact and combine mechanical, chemical, and biological treatment techniques to minimize water pollution — without requiring large amounts of space or complex operation.

How Does an STP for Hotels Work? — Treatment Process
Our sewage treatment hotel systems are designed with advanced technologies such as MBBR (Moving Bed Biofilm Reactor), SBR (Sequential Batch Reactor), and MBR (Membrane Bioreactor) to ensure maximum efficiency in treating organic waste, suspended solids, and pathogens. Regardless of the exact technology used, treatment follows four core stages:
1. Preliminary Treatment
This is the first step in processing hotel wastewater, also called mechanical or physical treatment, and it takes place before primary treatment. Incoming wastewater (influent) passes through mechanical bar screens that remove rags, sticks, paper, cans, and other coarse solids. A grit chamber removes sand and grit, and this stage also removes a significant amount of oils and greases — protecting pumps and downstream equipment from damage.
2. Primary Treatment
Also known as physical-chemical treatment, this stage removes organic and inorganic solids through sedimentation and flotation before biological treatment begins. Partially treated wastewater flows through a primary clarifier (sedimentation tank), where the flow slows down to allow heavier solids to settle at the bottom as primary sludge, while floating grease and oil are skimmed off the surface. This stage typically removes about 50–60% of suspended solids and reduces BOD levels by 30–40%.
3. Secondary Treatment (Biological Treatment)
This stage uses biological processes — such as the Activated Sludge Process, MBBR, or SBR — to break down organic matter. Primary effluent enters an aeration tank where it’s mixed with microorganisms and aerated, encouraging bacterial growth that consumes the remaining organic matter. The aerated wastewater then moves to a secondary clarifier, where solids settle out as secondary sludge; part of this sludge is recirculated back to the aeration tank to sustain the biological process. Secondary treatment typically removes about 80–90% of organic solids.
4. Tertiary Treatment (Disinfection)
The final stage removes any remaining suspended or dissolved solids and disinfects the water to eliminate disease-causing microorganisms. This is done using disinfectants such as chlorine, ozone, or UV light. The treated water is now clean enough to be safely discharged or reused for gardening, flushing, cooling systems, and other non-potable applications.

Frequently Asked Questions
Many hotels, especially those outside city centers or in developing areas, aren’t connected to a main sewerage system, or local pollution control norms require on-site treatment before any discharge. An STP lets the hotel treat and safely reuse or discharge its own wastewater independently.
MBBR is compact and handles fluctuating loads well, making it popular for hotels with variable occupancy. SBR works well where space allows for batch processing. MBR delivers the highest effluent quality through membrane filtration, suited for hotels wanting to reuse treated water for higher-grade applications. The right choice depends on your hotel’s size, space, and reuse requirements — our team can recommend the best fit.
Space requirements depend on plant capacity and technology chosen. MBBR and package plants are designed to be compact, making them suitable even for hotels with limited available space. Contact us with your daily wastewater volume for a space estimate.
Standard delivery time is around 30 days from order confirmation, with installation and commissioning scheduled separately based on site readiness.
