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.
Sewage Treatment Plant in Assam — Why It Matters
Assam covers a wide spread of industrial and regulatory activity, from Amingaon Industrial Estate, Bongaigaon Petrochemical, Dibrugarh Industrial, Tinsukia Industrial Area to fast-growing residential markets. Rather than one generic Assam-wide page, Optima maintains a dedicated, locally detailed page for each Assam city we actively serve — including Guwahati — each covering that city's specific regulatory body, local industrial zones, and pricing.
This page exists as a starting point to help you find the right one. Assam Pollution Control Board (APCB) enforces effluent norms. Tea, petrochemical, and paper industries face strict ETP requirements. STPs mandatory for large hotels and commercial complexes in Guwahati.
