Retrofit effectiveness assessment cycle reduced from 6 months to real-time

Solution Details

Stormwater-Sewage Separation Online Monitoring System Solution

The Stormwater-Sewage Separation Online Monitoring System Solution is a comprehensive, intelligent platform designed to tackle urban water pollution by precisely identifying and managing cross-connections between stormwater and sewage networks. It provides regulatory compliance and actionable insights for effective pollution control.

Policy Background for Urban Water Pollution Control

Effective stormwater-sewage separation is a critical requirement for urban water body pollution control. Regulatory frameworks are increasingly mandating the elimination of direct sewage discharge and the implementation of fully separate drainage systems.

Cross-connections between stormwater and sewage networks remain a major contributor to urban water pollution, necessitating advanced monitoring solutions for identification and management.

Technical Highlights: Multi-dimensional Monitoring and Intelligent Recognition

Ecolor's stormwater-sewage separation monitoring system employs a three-dimensional "flow + level + water quality" monitoring approach for the precise identification of cross-connections and overflow pollution events.

The system utilizes dry-weather baseflow analysis to establish normal flow baselines, rainfall response models to predict overflow risks, and water quality fingerprinting technology for rapid pollution source tracing and analysis.

Key System Features and Capabilities

Real-Time Network Monitoring

Continuous monitoring of level and flow within both stormwater and sewage networks.

Automatic Discharge Identification

Automatic identification of illicit dry-weather sewage discharge and wet-weather overflow events.

Online Water Quality Analysis

Multi-parameter online water quality monitoring for COD, ammonia, pH, and other key indicators.

GIS Visualization & Tracing

GIS map visualization with integrated tools for pollution source tracing and spatial analysis.

Storm Warning & Dispatch
