STP, ETP & ZLD Compliance Services in India

STP / ETP, Water Recycling & ZLD Solutions for Industrial & Infrastructure Projects

Sewage Treatment Plants (STP) and Effluent Treatment Plants (ETP) are mandatory systems for treating domestic sewage and industrial effluent.

Zero Liquid Discharge (ZLD) systems ensure complete reuse of treated water with no external discharge.

Industries must comply with Pollution Control Board (PCB) consent conditions, Environmental Clearance (EC) requirements, and CPCB/SPCB norms.

Simplicomp Tech LLP provides technical, operational, and compliance support across STP, ETP, water recycling, and ZLD systems.

STP / ETP, Water Recycling & ZLD Compliance Services

Wastewater treatment and reuse systems must be designed, installed, operated, monitored, and optimised to meet CPCB/SPCB discharge standards, consent conditions, EC requirements, and circular water management goals.

Simplicomp supports organisations with system performance monitoring, compliance audits, operational advisory, treated effluent testing coordination, water reuse planning, ZLD compliance support, and regulator-aligned documentation to ensure uninterrupted wastewater and water sustainability compliance.

Ask Your Question

What is the difference between STP and ETP?

STP treats domestic sewage, while ETP treats industrial effluent containing chemicals and contaminants.

Is STP or ETP mandatory for industries?

Yes, industries and projects generating wastewater must install STP or ETP systems as per Pollution Control Board norms.

What is Zero Liquid Discharge (ZLD)?

ZLD is a system where all wastewater is treated and reused, ensuring no liquid discharge outside the facility.

Are water recycling systems mandatory?

In many cases, regulatory authorities mandate water recycling to reduce freshwater consumption and ensure sustainability.

What happens if wastewater compliance is not maintained?

Non-compliance can lead to penalties, plant closure, environmental damage, and loss of approvals.
