Sewage Treatment Plant Manufacturer in India

With rapid urbanization, commercial development and stricter environmental regulations in India, the demand for sewage treatment plant is increasing across every sector. For residential societies, hotels, hospitals, IT parks and industrial facilities, simply installing an STP  plant is no longer enough-the STP's long-term performance, compliance and ease of operation have become paramount.

Netsol Water is more than 15 years of experienced Sewage Treatment Plant Manufacturer in India, we not only supply equipment, but also provide complete, practical solutions, from design to commissioning and operation, that work for Indian site conditions.

About Netsol Water

Netsol Water's focus isn't limited to STP supply. We are a process-driven manufacturer and solution provider where every project is designed based on actual site conditions and operational challenges. STP projects seem simple on paper, but their success on the ground depends on process design, civil coordination and correct technology selection. Incorrect design or an over-simplified approach causes many STPs to experience performance issues within months.

Our team:

. Conducts a detailed analysis of sewage characteristics

. Selects the right treatment technology

. Plans civil, mechanical, and electrical coordination

. And ensures practically stable operation after commissioning

This approach ensures Netsol Water's sewage treatment plants deliver reliable output under real-world conditions, whether the site is residential or industrial.

Sewage Treatment Plant Technologies We Manufacture

Not every site is suitable for a single technology. Therefore, we design and manufacture multiple STP technologies, with selection based on client requirements and site conditions.

1: MBBR (Moving Bed Bio Reactor)

MBBR technology is widely preferred for its compact footprint and stable performance. It is ideal for residential complexes, hotels, and commercial buildings where space is limited and treated water reuse is planned.

2: SBR (Sequencing Batch Reactor)

SBR systems are suitable for projects where inflow variation is high. With proper automation, this technology delivers excellent treated water quality, but operational discipline is essential.

3: ASP (Activated Sludge Process)

ASP technology is effective when sufficient space is available and trained operation staff are present. We recommend ASP systems only for sites where long-term operation is feasible.

4: Tertiary & Advanced Treatment

For treated water reuse, we integrate pressure sand filters, activated carbon filters, UF, and disinfection systems so that the water can be safely reused for flushing, gardening, or cooling.

Netsol Water Manufacturing & Execution Approach

The performance of an STP depends not only on the reactor technology, but also on overall system integration. Therefore, in every project, we ensure:

. Proper hydraulic design for gravity flow

. Correct blower, pump, and diffuser selection

. Durable materials of construction (MS, SS, FRP)

. Odor control and sludge handling planning

. Automation that is operator-friendly, not complicated

Equipment is dispatched to the site only after strict quality checks at the manufacturing stage, avoiding unwanted modifications after installation.

STP Capacity Range & Applications

We manufacture and execute sewage treatment plants ranging from 10 KLD to multi-MLD capacity, including:

. Residential societies & townships

. Commercial buildings & IT parks

. Hotels & hospitals

. Educational institutions

. Industrial & mixed-use developments

Each application has a different design philosophy, which we implement based on practical experience.
