STP Capacity Calculator
STP Capacity Calculator — quick estimate
Estimate daily sewage generation and the right sewage treatment plant (STP) capacity in KLD for your building — and how much treated water you can reuse. Adjust the inputs, then get an engineered design.
Your building
Sewage ≈ water demand × return factor. STP capacity is rounded up to a standard size with a peak-flow allowance. CPCB / PCB norms apply for discharge & reuse.

Our team will size and specify the STP (SBR / MBBR / MBR), reuse network and PCB documentation for your project. We'll attach the estimate above automatically.

Thanks! Our team will send your tailored STP design & capacity within one business day.
Indicative estimates only — not a binding design. Actual STP sizing depends on occupancy pattern, inlet characteristics, technology and PCB consent conditions.
Need an exact BOQ, rate analysis or measurement sheet?
This is a quick engineering estimate. For tendering, billing or audit, our QS & estimation team prepares an item-wise BOQ, rate analysis and a verified measurement sheet to IS / CPWD norms — backed by 15+ years and ISO 9001:2015 quality processes.
