Delhi, being one of the most densely populated cities in India, faces enormous challenges in managing domestic and municipal wastewater. With growing urbanization, housing complexes, hospitals, commercial spaces, hotels, and industries generate large volumes of sewage every day. This untreated sewage, if not properly managed, can pollute the Yamuna River and underground water sources, leading to health hazards and environmental degradation.
This is where Sewage Treatment Plants (STPs) play a vital role. These systems are designed to treat and recycle sewage water, making it safe for reuse or discharge. As a trusted Sewage Treatment Plant Manufacturer in Delhi, we provide efficient, compact, and eco-friendly STP systems tailored for urban and semi-urban environments. Whether it's a small residential complex or a large industrial unit, we offer customized solutions that meet the sewage treatment norms laid out by CPCB and DPCC.

How Does a Sewage Treatment Plant Work?
Our STPs are designed to ensure effective wastewater treatment in a step-by-step manner. The typical flow of treatment includes:
Primary Treatment
Screening of large debris, rags, and solids
Grit removal and sedimentation of suspended particles
Secondary/Biological Treatment
Aeration tanks where microorganisms break down organic matter
Technologies used include MBBR (Moving Bed Biofilm Reactor), SBR (Sequencing Batch Reactor), or ASP (Activated Sludge Process)
Tertiary Treatment
Final polishing of the effluent using sand filters, activated carbon, UV or chlorination
Ensures water is free from pathogens and turbidity
Sludge Treatment
Sludge dewatering and drying for safe disposal or use as bio-fertilizer
Our STPs can be PLC-controlled and include features like remote monitoring, auto-sludge handling, and odor control units, making them ideal for modern infrastructure.
