SUSBIO was founded in 2013 by Akshat and Raghavendra with a straightforward but ambitious mission: to bring professional-grade, genuinely effective sewage treatment to Indian buildings of every size and type — not just large municipal projects or major industrial clients, but the villa owner in Goa, the apartment RWA in Pune, the boutique hotel in Coorg, the school hostel in Rajasthan, and the factory in Gujarat.
In the decade since, SUSBIO has grown into one of India’s leading wastewater treatment companies — engineering, manufacturing, installing, and servicing packaged sewage treatment plants across hundreds of projects in every segment: residential, commercial, hospitality, healthcare, educational, and industrial. The company’s flagship product line, SUSBIO ECOTREAT, is manufactured at SUSBIO’s production facility under factory-controlled quality conditions and has earned CPCB (Central Pollution Control Board) approval — the most authoritative regulatory certification for STPs in India.
But what defines SUSBIO is not just what it manufactures. It is what it stands behind. Every SUSBIO ECOTREAT system leaves the factory with a 10-year module warranty and SUSBIO’s lifetime service commitment — a promise that no other STP manufacturer in India makes with the same consistency and accountability.
Akshat, Founder -- SUSBIO (Founded 2013)
When I started SUSBIO, I kept seeing the same problem: building owners across India were either ignoring sewage treatment entirely -- running the environmental and legal risk -- or buying cheap, unapproved systems that failed within a few years. Neither was acceptable. My goal was to engineer a packaged STP that a villa owner, a hotel operator, and a hospital administrator could all trust equally -- CPCB approved, genuinely effective, and supported for life. That is what ECOTREAT is. That is what SUSBIO is.
10 Years of Experience: What SUSBIO Has Learned from 500+ STP Projects
Over 500 STP installations across India is not just a number — it is a decade of real-world engineering insight that no textbook or product catalogue can replicate. Here is what SUSBIO has learned, and how it shapes every ECOTREAT system we build today:
1. Sizing Is Everything — and It Is Almost Always Wrong
The single most common mistake SUSBIO encounters in the field is incorrect STP sizing — almost always undersized. Generic design assumptions underestimate actual sewage loads from hotel kitchens, hospital laundries, and apartment blocks with more occupants than the building plan suggests. Every SUSBIO installation begins with a rigorous site assessment and actual flow verification — not assumptions.
2. Outlet Quality Is Non-Negotiable — Not a Range
Many STP manufacturers quote outlet quality as a range: ‘BOD 20-50 mg/L.’ SUSBIO does not. Every SUSBIO ECOTREAT system is designed and tested to deliver BOD below 10 mg/L and TSS below 20 mg/L as a consistent guarantee — not an aspiration. The dual Anaerobic + MBBR treatment process makes this possible regardless of daily flow variations.
3. Service After Installation Is Where Most STPs Fail
SUSBIO’s 500+ installation track record includes inheriting a significant number of failed or failing systems from other manufacturers — systems that performed adequately for 2-3 years, then degraded because the supplier had no service infrastructure. SUSBIO’s lifetime service commitment exists because we know that an STP without long-term service support is not a solution — it is a deferred problem.
4. Regulatory Documentation Is Half the Battle
Building owners frequently discover that having an STP installed is not enough — they need the right documentation for SPCB Consent to Operate, NGT compliance, NABH accreditation, and trade licence renewals. SUSBIO’s team prepares and supports CTE and CTO documentation for every installation, ensuring clients are not just compliant in practice but demonstrably compliant on paper.
5. FRP Outlasts Everything Else
After 10+ years of field experience across India’s climate zones — from coastal humidity in Goa and Kerala to extreme heat in Rajasthan and Gujarat — SUSBIO’s choice of FRP (Fibre Reinforced Plastic) as the construction material for all ECOTREAT vessels is validated every day. FRP shows no corrosion, no cracking, no structural degradation. Mild steel tanks rust within 3-5 years in coastal environments. RCC chambers develop cracks and leakage. FRP simply does not.
The SUSBIO ECOTREAT Range: Industrial-Grade Technology for Every Building Size
SUSBIO’s ECOTREAT product range covers every capacity from 2 KLD to 20 KLD and beyond — all using the same proven dual-stage Anaerobic + MBBR technology, all CPCB approved, all manufactured under factory-controlled quality conditions, and all backed by the same 10-year module warranty and lifetime service commitment.
| ECOTREAT Model | Capacity | Serves | Technology | Price |
|---|---|---|---|---|
| ECOTREAT 2 KLD | 2,000 L/day | ~5 persons | Anaerobic + MBBR | Rs. 3 Lakhs |
| ECOTREAT 5 KLD | 5,000 L/day | ~25 persons | Anaerobic + MBBR | Rs. 5.25 Lakhs |
| ECOTREAT 10 KLD | 10,000 L/day | 40-50 persons | Anaerobic + MBBR | Rs. 8.5 Lakhs |
| ECOTREAT 15 KLD | 15,000 L/day | 75-80 persons | Anaerobic + MBBR | Rs. 10.65 Lakhs |
| ECOTREAT 20 KLD | 20,000 L/day | 110-120 persons | Anaerobic + MBBR | Rs. 13 Lakhs |
All ECOTREAT models are CPCB Approved, use FRP construction rated for 25+ year service life, feature built-in silent diaphragm air pumps, and support treated water reuse for toilet flushing and garden irrigation. For capacities above 20 KLD, SUSBIO provides custom-engineered packaged STP solutions.
SUSBIO's Track Record: Real Projects, Real Performance

Every STP manufacturer in India claims quality. SUSBIO backs its claims with five specific, documented commitments that set it apart from every competitor in the market:
Commitment 1: CPCB Approval on Every Unit
Every SUSBIO ECOTREAT system carries CPCB (Central Pollution Control Board) approval. This is not a company-level certification or a one-time test report — it is a product-level approval that applies to every unit SUSBIO manufactures and delivers. For building owners, this means regulatory protection that no unapproved system can provide.
Commitment 2: Guaranteed Outlet Quality
Every SUSBIO ECOTREAT system guarantees outlet water quality of BOD below 10 mg/L, COD below 50 mg/L, TSS below 20 mg/L, and fecal coliform below 100 MPN/100 mL. These are not design targets — they are performance guarantees backed by factory testing before dispatch and field verification at commissioning.
Commitment 3: Factory Pre-Testing Before Dispatch
Every SUSBIO ECOTREAT unit is pressure-tested and functionally verified at SUSBIO’s manufacturing facility before it is dispatched to the project site. This factory quality control step eliminates site-stage surprises and ensures that the system performs to specification from day one of commissioning.
Commitment 4: 10-Year Module Warranty
SUSBIO provides a 10-year warranty on every ECOTREAT module — the longest module warranty available from any STP manufacturer in India. This warranty reflects SUSBIO’s confidence in its FRP construction, its MBBR carrier media, and its overall system engineering.
Commitment 5: Lifetime Service
SUSBIO’s lifetime service commitment means that every client who installs a SUSBIO ECOTREAT system has access to SUSBIO’s service engineers for the entire operational life of the system — not just during the warranty period. This includes scheduled maintenance visits, desludging services, performance testing, spare parts supply, and regulatory documentation support. SUSBIO’s service network covers every major city and industrial cluster across India.
