Smart Data Infrastructure for Wet Weather Control and Decision Support

Wet weather can significantly increase flows at wastewater treatment facilities, creating operational challenges and potentially affecting treatment efficiency, reliability, and control of treatment units at these facilities. In recent years municipalities and utilities have been considering how they can improve their operations and infrastructure by drawing on recent technological advances.

This document focuses on how municipalities, utilities, and related organizations can use advances in technology to implement “smart data infrastructure” for wet weather control—that is, how they can use advanced monitoring data to support wet weather control and decision-making in real time or near real time. This document was originally developed in August 2018, the March 2021 version updated existing case studies with new information and added new case studies.
