Sewage Treatment Plant Design, Supply & Installation | Eco Paryavaran
Most STP failures we’ve seen in the field aren’t technology failures — they’re specification failures. The plant was designed for a theoretical flow that doesn’t match real usage patterns, or sludge handling was treated as an afterthought, or the chosen technology requires more operator attention than the facility can provide. Getting the design right upfront saves a significant amount of retrofitting cost and regulatory trouble down the line.
Eco Paryavaran, based in Mohali, Punjab, designs, supplies, and installs sewage treatment plants for housing societies, hospitals, hotels, industrial campuses, and municipal bodies across India. We handle the full project cycle — from initial capacity and technology selection through Consent to Establish documentation, civil and electromechanical works, commissioning, and operator training.
STP Design: Matching Technology to Facility Type
The technology choice for an STP depends on four things: the hydraulic load and its variation, the BOD load profile, the available footprint, and what happens to the treated water. A housing society that wants to reuse treated water for landscaping has different requirements from a hospital that primarily needs compliant discharge to the city drain.
For capacities between 50 KLD and 2 MLD, SBR (Sequencing Batch Reactor) is our most commonly specified technology — compact footprint, robust performance, and manageable OPEX. For facilities requiring treated water quality suitable for reuse in cooling towers or flushing applications, we use MBR (Membrane Bioreactor) technology. For industrial applications with variable BOD loads, MBBR (Moving Bed Biofilm Reactor) systems handle fluctuations better than SBR.
Our STP Project Scope
Eco Paryavaran’s STP projects cover capacity assessment and technology selection, detailed engineering drawings, BOQ preparation, SPCB Consent to Establish (NOC) application, supply of electromechanical equipment, civil construction coordination, piping, electrical, and instrumentation works, commissioning and performance testing, and operations and maintenance training. We take responsibility for the plant performing to its designed parameters — not just for delivering the equipment.
For larger projects requiring formal environmental approvals, we can integrate the STP within the broader Environmental Impact Assessment process. For facilities also managing solid waste from the same site, our solid waste management consultancy covers that dimension. Treated water quality verification is handled through our in-house NABL environmental testing laboratory.
SPCB Compliance for STPs
Any STP above 10 KLD capacity requires a Consent to Establish from the State Pollution Control Board before construction begins, and a Consent to Operate after commissioning. The consent conditions specify discharge standards — typically BOD <10 mg/L, TSS <10 mg/L, and Coliform <100 MPN/100 ml for treated water intended for reuse. Our team prepares the consent applications and handles queries from PPCB or HSPCB, reducing delays in your project timeline.
Eco Paryavaran also provides comprehensive solid waste management consultant services, Environmental Impact Assessment (EIA) studies, and ozonation water treatment solutions for complete environmental compliance.
