How Flow Technology Can Ease The Inflow And Infiltration Headache

Rain-dependent inflow and infiltration (RDI&I) is a headache for every wastewater treatment plant (WWTP). Collection systems operators attempt to manage RDI&I through careful measurement. Yet many measurement strategies and technologies do not yield the kind of high-quality data that can help pinpoint issues and direct necessary actions.

This can cause precious funds to be wasted on efforts that do little to help mitigate and manage inflow and infiltration issues (RDI&I). As such, operators need to understand how and why such methods often fail, as well as what is needed to produce the level of data quality that can detect, understand, and manage it. In this article, we’ll be assessing the challenges with legacy measurement methods for addressing inflow and infiltration studies, what elements of RDI&I influences collection system data on a macro scale, and what is being done differently to address these issues.
