Sewage Treatment Plant (STP) Manufacturer & Supplier in Pune

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.

Pune's STP demand splits cleanly between two very different buyers: the IT and residential belt around Hinjewadi and Baner, and the manufacturing belt around Chakan, Ranjangaon, and Pimpri-Chinchwad. The first group wants a quiet, low-maintenance plant that will not bother residents living above or beside it. The second group is dealing with MPCB's Red and Orange category rules and needs a system that can handle industrial-strength effluent alongside domestic sewage from staff facilities.

Pune's auto and auto-ancillary manufacturing base around Chakan and Ranjangaon means a meaningful share of our local projects are combined STP plus pre-treatment setups, where wash-water and workshop effluent get screened before joining the domestic stream. This is different from a straightforward residential STP and needs its own design sign-off from MPCB.

We keep a standing team in Pune given the volume of projects across Pimpri-Chinchwad, Hadapsar, and Bhosari, which shortens the gap between enquiry and site visit compared to a one-off project shipped in from outside the city.

For Pune's residential and township projects, particularly the large developments around Wagholi, Hinjewadi, and Kharadi, we default to MBBR technology sized for 100 to 1,000 KLD. It is the most cost-effective option for steady daily occupancy and gives residents treated water suitable for garden and flushing reuse without the higher running cost of a membrane system.

For manufacturing sites in Chakan, Ranjangaon MIDC, and Bhosari, the design brief changes. These plants often need an oil-and-grease trap or equalisation tank ahead of the biological stage to handle the variability of factory shift patterns, and MPCB inspectors in this belt pay close attention to whether pre-treatment is in place before effluent reaches the main STP. We design for this from the outset rather than retrofitting pre-treatment after an inspection flags it.
