Sewage Treatment Plants — Compact, Compliant, Low-Odour
MBBR, SBR and MBR designs that fit tight basements and rooftops, with treated water clean enough to reuse on-site.

Why it matters
The one upgrade your industrial water has been waiting for.
PCB-compliant on day one, with full documentation
- PCB-compliant on day one, with full documentation
- Reusable treated water for flushing, gardening, cooling
- Lower fresh-water spend and stronger ESG/BRSR score
Why on-site sewage treatment is no longer optional in India
CPCB and state PCB norms mandate on-site sewage treatment for apartments, hotels and commercial buildings above defined thresholds. Beyond compliance, recycled sewage cuts fresh-water demand 30–40% — strengthening ESG and water-security scorecards.
Where this shows up
- Apartments and gated communities above PCB thresholds
- Hotels, resorts and convention centres
- Hospitals and healthcare campuses
- IT parks, offices and educational institutions
How to identify the problem
- PCB notice or occupancy-certificate hold-up
- Resident complaints of odour from existing STP
- Fresh-water tanker dependence rising every year
- Existing plant underperforming on BOD / TSS norms
What happens if you don't solve it
- PCB notices, fines and occupancy-certificate hold-ups
- 30–40% higher fresh-water bills and tanker dependence
- Odour complaints, resident dissatisfaction, reputation loss
How Sewage Treatment Plants solves it
- MBBR / SBR / MBR / conventional ASP — chosen by site constraint
- Aqua Sutra packaged STPs commissioned in 30–45 days
- Treated water ≤ 10 BOD / ≤ 50 TSS, reuse-ready
- PCB-ready documentation, operator support, SCADA dashboards

Sewage Treatment Plants — your questions, answered
The exact things buyers ask us before going ahead — grouped so you can jump to what matters.
Understanding the problem
Is an STP mandatory for my building or layout?+
Yes — CPCB and most State Pollution Control Boards mandate STPs for any project generating over 20 KLD of sewage (apartments, hotels, hospitals, malls, layouts).
What technology should I use — SBR, MBBR, MBR or SAFF?+
Depends on space, treated-water quality target and budget. MBBR is the most popular for residential; MBR is ideal where space is tight and recycled water needs to be reused for flushing/landscaping.
Choosing the right system
How much treated water can I reuse?+
Typically 60–80% of sewage can be recycled for flushing, gardening and cooling-tower makeup — directly cutting your fresh-water purchase.
Installation, space & cost
How much space does an STP need?+
A 100 KLD MBBR plant needs roughly 100–150 m² (underground). MBR systems take 30–40% less space. We share full civil drawings during design.
Underground / containerised / packaged — which fits me?+
Underground RCC for large layouts, packaged FRP/MS for compact sites, and containerised STPs for sites that need fast deployment or relocation later.
Maintenance & longevity
Do you handle PCB compliance and reporting?+
Yes — we deliver online monitoring (OCEMS) integration, monthly compliance reports, sludge management and operator manning if required.
