About SENEVEN

Shanghai SENEVEN Environmental Technology Co., Ltd. (SENEVEN®), founded in 2008, is an innovation-driven enterprise deeply rooted in frontier technologies for environmental pollution prevention and control, dedicated to delivering end-to-end systematic solutions.

Brand Philosophy & Vision

We hold to the core principle of "Precise, Truth" (甚于诺, 致于微) — grounded in integrity, empowered by technology, and led by wisdom — safeguarding our clients’ project safety and environmental responsibility. We understand that in environmental engineering a hair-line deviation can compound into miles of error; only through relentless precision can we go far.

Core Technology & Applications

SENEVEN focuses on the integrity and safety of containment liner systems. With industry-leading geomembrane leak detection and continuous online monitoring, we provide critical technical support for landfills, mining, chemical industry, water-conservancy, and other major national projects.

Service Matrix & Closed Loop

Building on this foundation, our professional services extend into environmental safety assessment, completing a full-cycle closed-loop service flow — from preventive monitoring through to investigation and evaluation.

Conscience-Led

Sincerity and a deep sense of social responsibility — safeguarding the safety and reliability of every project.

Technology-Empowered

Advanced detection technology and intelligent monitoring systems deliver precise data for every project.

Wisdom-Driven

Drawing on extensive engineering experience and industry insight to design rigorous, scientifically grounded solutions.

Core Business

A closed-loop service flow — from preventive monitoring to investigation & evaluation.

1New Liner Integrity Inspection

For new lining projects, SENEVEN performs precise, comprehensive geomembrane leak-detection prior to commissioning, ensuring conformance with design and controlling environmental risk at source.

2Long-Term Online Leak Monitoring

A cloud-based intelligent monitoring system delivers continuous 24/7 surveillance, detecting potential leakage early and issuing alerts before risks materialize.
