FAQs
What is an STP Capacity Calculator?
A tool to estimate the sewage treatment capacity required for any project.
How is STP capacity calculated?
Capacity = No. of people × Daily water usage × 0.8 (sewage generation factor).
Daily water use per person?
Typically 135 liters/day for residential setups.
What is the sewage generation factor?
Usually 80% of total water used is considered as sewage.
Should I consider a buffer in the capacity?
Yes, adding 10–20% extra capacity helps handle peak loads.
Is the result in KLD?
Yes, output is in KLD (Kilo Litres per Day).
Suitable for retrofitting buildings?
Yes, especially when evaluating if existing capacity is sufficient.
