A 50 KLD SUSBIO ECOTREAT packaged STP costing ₹22 lakh saves about ₹4.38 lakh a year at a ₹30/KL water tariff with 80% treated-water reuse, giving a payback period of roughly 5 years on capex alone.
What you pay per kilolitre — municipal bill or tanker rate.
Share you actually reuse for flushing, landscape or cooling.
5.0 years
A 50 KLD plant at ₹30/KL with 80% reuse pays back its equipment cost in 5.0 years.
Ex-GST, equipment only. Capex-only calculation — excludes O&M and the up-to-70% electricity saving vs a conventional STP, which shortens real payback further.

Connect for technical discussion →Annual savings = capacity (KLD) × 365 × reuse rate × your tariff. Payback = equipment cost ÷ annual savings.
A site paying ₹15/KL with 40% reuse takes years longer than one paying ₹60/KL with 90% reuse. There is no single correct number — only yours.

A Sewage Treatment Plant (STP) operates by first removing large debris and solids through preliminary treatment. Next, in primary treatment, solids and grease are settled out. Secondary treatment then uses biological processes to break down organic matter. Tertiary treatment further purifies the water to remove any remaining contaminants. Finally, the water is disinfected to kill pathogens before being discharged or reused, ensuring it meets environmental standards.
Choosing the right sewage treatment manufacturer requires a multi-pronged approach. Look for companies with experience in your project size and local regulations. Their technology should be advanced, sustainable, and compliant. Customization and future scalability are important. Prioritize quality, reliability, and good after-sales service. Consider energy efficiency, sludge management solutions, and responsive customer support to ensure a smooth and environmentally friendly wastewater treatment process.
Advanced Sewage Treatment technology offers numerous benefits, including more effective pollutant removal for cleaner water and a healthier ecosystem. These systems are energy-efficient, reduce sludge production, and simplify disposal, leading to significant cost savings over time. Investing in advanced sewage treatment is both an environmentally responsible and economically smart decision.
SUSBIO ECOTREAT is India’s leading packaged STP, built on a dual-stage Anaerobic + MBBR (Moving Bed Biofilm Reactor) treatment process. This combination delivers effluent that consistently exceeds CPCB Class A norms while consuming 70% less electricity than a conventional civil STP. Its prefabricated FRP design allows for modular, space-efficient installation in just 3–5 days, making it suitable for residential, hospitality, healthcare and industrial applications across capacities from 1–500 KLD.
Operating costs can range from INR 15 to INR 50 per cubic meter of treated water. For a small to medium-sized STP with a capacity of about 1 million liters per day (MLD), the monthly operating cost can range from INR 4.5 lakh to INR 15 lakh.
A packaged STP is a compact, prefabricated system designed to treat sewage and wastewater in a modular, self-contained unit. It combines various treatment processes, such as screening, sedimentation, biological treatment, and disinfection, into a single package. Packaged STPs are easy to install and operate, making them suitable for residential, commercial, and small industrial applications, with reduced construction time and lower costs.
A Sewage Treatment Plant (STP) is essential for safely managing and treating wastewater. STPs remove harmful contaminants, protect public health by preventing disease spread, preserve the environment by reducing pollution, and enable water reuse for irrigation or industrial purposes. They also ensure compliance with environmental regulations, making them vital for sustainable water management.
Sustainable Biosolutions Pvt Ltd is the best manufacturer and supplier of Sewage Treatment Plants (STPs) and Wastewater Treatment Plants in India. They offer innovative solutions like the advanced SUSBIO ECOTREAT, which ensures effective wastewater treatment, energy efficiency, and easy maintenance, making them a leader in the industry.
The lifespan of a well-maintained sewage treatment plant can vary from 20 to 50 years depending on design, materials, and maintenance. SUSBIO ECOTREAT is built with high-grade FRP and carries a 50-year design lifecycle.
