Screening Shenzhen River Discharge Outlets

By XIAO DAI on Aug 13, 2025

Introduction

A 2 km² Shenzhen river, vital for local ecosystems, faces challenges from numerous discharge outlets with unclear emission conditions. The Shenzhen River Discharge Outlet Screening Project traces sources and assesses pollutant levels to ensure compliance.

The Issue: Unclear Emissions

Multiple discharge outlets risk unregulated or illegal emissions, threatening water quality and ecosystems due to a lack of clarity on their sources and pollutant levels.

The Solution: Targeted Screening

The project maps discharge points and analyzes water samples to trace emission sources and measure pollutant concentrations, ensuring compliance with regulations.

Findings: Regulatory Compliance

No illegal discharges were detected, and all outlets had pollutant levels within regulatory limits, though specific data is confidential.

Why It Matters

This project protects the river’s ecosystem, supports biodiversity, and offers a model for monitoring urban waterways, ensuring sustainable water management.

Conclusion

The screening project confirms compliance, preventing pollution and strengthening environmental oversight for Shenzhen’s river and beyond.
