What is a Sewage Treatment Plant?
A Sewage Treatment Plant (STP) is a facility that processes domestic and municipal wastewater to remove contaminants before the treated water is discharged or reused. The process involves physical, biological, and chemical treatment stages that remove suspended solids, organic matter, nutrients, and pathogens.
Modern STP systems use technologies including MBBR (Moving Bed Biofilm Reactor), MBR (Membrane Bioreactor), SBR (Sequencing Batch Reactor), and conventional activated sludge processes — each suited to different capacities and site conditions.
In India, STPs are mandatory for residential societies above 20,000 sqm built-up area, commercial complexes, hotels, hospitals, and all industrial facilities discharging domestic effluent — as per CPCB norms and local Pollution Control Board regulations.

Is a Sewage Treatment Plant mandatory in Guwahati?
Yes. As per CPCB and the Assam Pollution Control Board, STPs are mandatory for residential projects above 20,000 sqm, hotels, hospitals, industries, and commercial complexes in Guwahati. Non-compliance attracts penalties and can result in closure notices. Optima ensures full regulatory compliance.
What STP technology is best for residential societies in Guwahati?
For residential societies in Guwahati, MBBR (Moving Bed Biofilm Reactor) and MBR (Membrane Bioreactor) systems are most popular. MBBR is cost-effective for 50–500 KLD capacity. MBR gives higher quality treated water suitable for toilet flushing and horticulture reuse. We assess your site and recommend the best option.
How long does STP installation take in Guwahati?
A packaged STP (10–100 KLD) in Guwahati can be installed and commissioned within 4–8 weeks of order confirmation. Civil tank-based STPs take 8–16 weeks depending on capacity. We coordinate with your civil team and manage the full project timeline.
