Scattergraph Principles and Practice
Powerful Tools Representing Depth and Velocity Sewer Flow Data
The Scattergraph is a powerful tool that displays depth and velocity data from a sewer flow monitor. The resulting patterns form characteristic signatures that provide insight into the conditions within a sewer. The flow monitor data also leave distinct patterns that even allow the performance of the flow monitor itself to be evaluated.

Scattergraph Principles and Practice Series
The scattergraph is a powerful tool that displays depth and velocity data from a sewer flow monitor, and the resulting patterns form characteristic signatures that provide insight into conditions within a sewer. The Scattergraph Principles and Practice webinar series is designed as an educational resource for wastewater professionals to understand how to use scattergraphs to recognize various flow conditions and understand how they impact sewer capacity and performance. This topic will be covered in a multi-part webinar series.
