SUSBIO is aĀ packaged STP, ETP, and WTP manufacturerĀ serving Bangalore and Karnataka ā with manufacturing at Vasuli MIDC, Chakan, Pune and 500+ installations across 24 Indian states since 2013. Every SUSBIO ECOTREAT system is factory-fabricated, factory-tested, and KSPCB-compliant before delivery to site.
Bangalore is one of the most demanding cities in India for sewage treatment. The combination of rapid high-rise residential development, a dense IT park ecosystem, strict KSPCB enforcement, and BWSSB’s sewage connection requirements has created a situation where STP compliance is non-negotiable for any serious developer or facility manager in the city.
Yet the Bangalore market is also flooded with cheap packaged STPs ā systems sold at Rs. 1.5 to 2.5 lakhs for a 10 KLD capacity that look reasonable on paper and fail within 18 months. We know this because we regularly receive calls from Bangalore developers and RWAs who are looking to replace a system that has already failed. The KSPCB notice has arrived. The residents are complaining about odour. The system is producing BOD of 80 mg/L against aĀ KSPCBĀ limit of 30 mg/L. Now they need a solution urgently.
SUSBIO has been supplying and commissioning STPs, ETPs, and WTPs across Bangalore and Karnataka for over a decade. We understand the KSPCB approval process, BBMP building regulation requirements, and the specific wastewater challenges that Bangalore’s building typologies create. This page explains what you need to know to make the right STP decision for your Bangalore project.
The Bangalore STP Landscape ā What Makes This City Different
Bangalore has characteristics that make STP design and selection more complex than most Indian cities. Understanding these factors is essential before making a system selection.
KSPCB Enforcement Is Active and Getting Stricter
TheĀ Karnataka State Pollution Control BoardĀ has been one of the more actively enforcing SPCBs in India over the past three years. KSPCB inspections of residential complexes, IT parks, and industrial facilities in Bangalore have increased significantly, and the penalties for non-compliance ā including CTO cancellation and NGT referrals ā are being applied more rigorously than in many other states.
KSPCB requires BOD ā¤ 10 mg/L and TSS ā¤ 10 mg/L for treated water reuse ā which is stricter than the CPCB general standard of BOD ā¤ 30 mg/L. If your STP is producing BOD of 25 mg/L, you might pass a CPCB inspection but fail a KSPCB inspection. This is a critically important distinction that many STP suppliers in Bangalore do not clearly explain to their clients.
BWSSB Sewage Connection Requirements
The Bangalore Water Supply and Sewerage Board (BWSSB) has specific requirements for buildings connecting to the city’s sewerage network. Buildings above certain sizes are required to treat sewage on-site before discharging to the BWSSB sewer ā and the treated quality requirement is the KSPCB standard, not the more lenient CPCB general standard.
This means an STP that meets national minimum norms may still not meet BWSSB connection requirements. Always verify the applicable discharge quality standard with KSPCB and BWSSB before finalising your STP design.
High-Rise Residential Development
Bangalore’s residential development is dominated by high-rise apartments ā 20 to 40-floor towers with 200 to 600 units each. These buildings generate significant sewage volumes (100 to 400 KLD per tower) and have constrained utility space. The sewage generation profile is also highly variable ā intense peaks during morning and evening hours and very low flows through the night.
This load variability is a significant design consideration. A system sized for average daily flow will be hydraulically overloaded during morning peak hours.Ā MBBR technologyĀ handles this variability better than any other biological treatment process ā one of the core reasons SUSBIO ECOTREAT is the preferred system for Bangalore high-riseĀ residential projects.
IT Parks and Commercial Campuses
Bangalore’s IT corridor ā from Whitefield and Electronic City to Outer Ring Road and Hebbal ā houses some of India’s largest commercial campuses. These facilities generate domestic sewage from their employee population (canteens, washrooms) as well as, in some cases, process effluent from cooling towers and laboratory operations.
IT park STPs need to handle the specific sewage pattern of a commercial campus ā high volumes during working hours, near-zero volumes at night and on weekends. SBR technology with automated cycle adjustment is well-suited for this application, as is MBBR with appropriate equalization capacity.
KSPCB Discharge Standards ā What Your Bangalore STP Must Achieve
Karnataka’s discharge standards are among the strictest in India. The table below shows KSPCB requirements versusĀ CPCB general standardsĀ and what SUSBIO ECOTREAT consistently delivers:
| Parameter | CPCB General Standard | KSPCB Standard (Karnataka) | SUSBIO ECOTREAT Outlet |
|---|---|---|---|
| BOD (mg/L) | ā¤ 30 | ā¤ 10 (for reuse) | < 10 |
| COD (mg/L) | ā¤ 250 | ā¤ 50 (for reuse) | < 50 |
| TSS (mg/L) | ā¤ 100 | ā¤ 10 (for reuse) | < 10 |
| pH | 6.5 ā 8.5 | 6.5 ā 8.5 | 7.0 ā 8.0 |
| Ammoniacal-N (mg/L) | ā¤ 50 | ā¤ 10 | < 5 |
| Fecal Coliform (MPN/100mL) | ā¤ 1000 | ā¤ 100 (for reuse) | < 100 |
This is the table that matters most for Bangalore projects. Many STP suppliers quote CPCB general standards ā BOD 30, TSS 100 ā because their systems can only achieve that. SUSBIO ECOTREAT is designed to meet the KSPCB reuse standard of BOD < 10 and TSS < 10 as a routine outcome, not an exceptional one. If your supplier cannot tell you what their system achieves at KSPCB reuse standard ā ask why not.

Packaged STP vs Civil STP for Bangalore Projects
The choice between packaged and civil STP comes up in every Bangalore project. Here is an honest comparison specific to Bangalore’s project context:
| Table | Packaged FRP STP (SUSBIO ECOTREAT) | Civil RCC STP |
|---|---|---|
| Construction timeline | 3ā5 days ā fits tight project schedules | 3ā6 months ā delays occupancy certificate |
| Civil work required | Levelled plinth only | Extensive RCC construction |
| KSPCB compliance | Factory-tested to KSPCB reuse standard | Depends on design and construction quality |
| Footprint | 60% less than civil equivalent ā critical in Bangalore | Large area ā often not available in high-rise projects |
| Quality consistency | Factory-controlled manufacturing | Site-dependent ā varies by contractor |
| Odour control | Sealed FRP vessel ā no odour escape | Open RCC tanks ā odour risk in residential proximity |
| Scalability | Add parallel units as building phases complete | Costly structural modification needed |
| Warranty | 10-year module warranty | No standard warranty from contractor |
In Bangalore specifically, the timeline advantage of packaged STPs is significant. BBMP occupancy certificate processes are already lengthy. A civil STP requiring 3 to 6 months of construction adds directly to project completion delays. We have seen Bangalore developers choose packaged STPs specifically to protect their OC timeline ā and the saving in interest cost on delayed handover more than covers the cost difference.
STP Cost in Bangalore 2026 ā Realistic Price Guide
Bangalore has a wide range of STP suppliers at very different price points. The Rs. 1.5 to 2.5 lakh systems are real ā and so is the failure rate. Here are realistic cost ranges for properly engineered systems:

Frequently Asked Questions ā STP in Bangalore
Q1. Is an STP mandatory for my apartment project in Bangalore?
Yes. KSPCB and BBMP regulations require STPs for all residential projects generating sewage above defined thresholds ā typically 50 units or above, or projects with a built-up area exceeding 20,000 sq.m. BWSSB also requires on-site sewage treatment before connection to the city’s sewerage network for larger buildings. The specific threshold for your project depends on the project type and location within Bangalore. SUSBIO can confirm the applicable requirements for your specific project ā contact us at susbio.in/contact-us/
Q2. What KSPCB outlet standards must my Bangalore STP meet?
KSPCB requires BOD ā¤ 10 mg/L, TSS ā¤ 10 mg/L, COD ā¤ 50 mg/L, pH 6.5ā8.5, and fecal coliform ā¤ 100 MPN/100 mL for treated water reuse within the building ā which is the standard required by BWSSB for most Bangalore projects. Note that these are stricter than CPCB general standards. Always verify with KSPCB or confirm with SUSBIO before finalising your STP specification ā the applicable standard depends on whether you are discharging to drain or reusing treated water within the building.
Q3. How do I get KSPCB Consent to Establish (CTE) for my Bangalore project?
CTE requires submission of Design Basis Report, process flow diagram, site plan showing STP location, equipment list with specifications, and effluent disposal plan to the Karnataka State Pollution Control Board. After installation and commissioning, Consent to Operate (CTO) requires submission of performance test results showing KSPCB-compliant outlet quality across 3 to 7 consecutive days. SUSBIO prepares complete CTE and CTO documentation for every Bangalore project as part of the standard supply scope.
Q4. What is the difference between a packaged STP and a civil STP for a Bangalore apartment?
A packaged STP arrives factory-fabricated and tested ā it can be installed in 3 to 5 days. A civil STP is built on site using RCC construction, taking 3 to 6 months. For most Bangalore residential projects, packaged STPs are the practical choice because of constrained utility space, tight project timelines, and the quality consistency advantage of factory manufacturing. Civil STPs make more economic sense for very large capacity projects above 500 KLD where factory prefabrication becomes less cost-efficient.
Q5. Does SUSBIO provide service support in Bangalore?
Yes. SUSBIO provides Annual Maintenance Contracts for all installed systems in Bangalore and Karnataka. Our Pune engineering team handles remote monitoring and scheduled site visits. For urgent issues we provide same-day telephone support and dispatch the nearest available engineer. Contact us at +91 88889 80197 or info@susbio.in for service support queries.
Q6. What STP capacity does my Bangalore IT park need?
IT park STP sizing depends on your peak employee count and amenities. Use 45 LPCD for office use without canteen, 60 LPCD with canteen, and 80 LPCD for campuses with full-service food courts. Multiply peak employees by the applicable LPCD figure to get average daily flow, then add 20 to 25% for peak hour surge. A 5,000-person campus with canteen generates approximately 300 KLD. Use our STP capacity calculator at susbio.in/how-to-calculate-sewage-treatment-plant-capacity/ for an accurate estimate.
Q7. What is the typical STP cost for a 100-unit apartment in Bangalore?
A 100-unit apartment with average 3.5 occupants at 80% occupancy generates approximately 38 KLD of sewage. The appropriate STP capacity is 40 to 50 KLD allowing for safety margin. A SUSBIO ECOTREAT packaged STP at this capacity, supply and install, typically costs Rs. 15 to 22 lakhs depending on site conditions and civil scope. This includes the system, installation, commissioning, KSPCB documentation support, and 12-month warranty. Contact SUSBIO for a project-specific quotation.
