Sewage Treatment Plant (STP)
A Sewage Treatment Plant (STP) is a wastewater treatment system designed to treat domestic sewage generated from residential complexes, commercial buildings, institutions, and public facilities.
Sustainable Treatment of Domestic Wastewater
Sewage typically contains organic matter, suspended solids, nutrients, and microorganisms. An STP removes these contaminants through biological and physical treatment processes to produce treated water that can be safely discharged or reused.
Greenshield Enviro provides efficient Sewage Treatment Plant solutions, available from compact 10 KLD, 20 KLD, and 50 KLD plants to large-scale systems, designed to support sustainable water management and reduce environmental impact.
Designed for water reuse
Why STP is Important
Responsible wastewater management for urban and commercial infrastructure.
Domestic wastewater must be treated before discharge to prevent contamination of water bodies and protect public health.
Installing an STP helps facilities treat wastewater effectively, reduce pollution, reuse water for non-potable purposes, secure pollution control board approvals, and support environmental responsibility.
Practical parameters designed around site conditions
The system design depends on wastewater characteristics, flow, available space, construction preference, and reuse requirement.

How a Sewage Treatment Plant Works
Step-by-step sewage treatment cycle for cleaner discharge and reuse-ready water.
01Screening
Screening
Large solids and debris are removed from incoming sewage.
02Equalization
Equalization
Wastewater flow is balanced to maintain stable treatment conditions.
03Biological
Biological Treatment
Microorganisms break down organic contaminants in aeration tanks.
04Clarification
Secondary Clarification
Settled sludge is separated from treated water.
05Disinfection
Filtration & Disinfection
Filtration and disinfection improve water quality before reuse or discharge.
Built for facilities that generate domestic wastewater
These facilities generate wastewater that must be treated before discharge.

Easier pollution control board approvals and CTO compliance
Wastewater discharge standards need responsible treatment
Central Pollution Control Board
Wastewater discharge standards are regulated by authorities such as the Central Pollution Control Board (CPCB).
State Pollution Control Boards
Including Haryana State Pollution Control Board (HSPCB), Uttar Pradesh Pollution Control Board (UPPCB), and Delhi Pollution Control Committee (DPCC).
Responsible Management
STP systems help facilities treat sewage, obtain Consent to Establish (CTE) and Consent to Operate (CTO) approvals, and maintain environmentally responsible wastewater management.
