What is flow? For those of us in the water resources field, it is obvious from our everyday work and experience. But there are some nuances and details about flow that are important to understand. In this post, I will cover the basic concepts of flow, including some...

Why is my engineer asking me for so much data? Best practices for flow and rainfall data collection for sanitary collection systems.  This blog post was adapter to an article in the April 2020 issue of Water Environment and Technology. Here is a link to download a PDF...

Last month we shared an update that the H2Ometrics platform was expanded to include several new water quality parameters for the H2Ometrics entry as part of team GLASS for the Cleveland Water Alliance’s Internet of H2O Challenge. We are pleased to announce that team...

The H2Ometrics platform has expanded to include several new water quality parameters. The additional parameters were added for the H2Ometrics entry as part of team GLASS for the Cleveland Water Alliance’s Internet of H2O Challenge. The challenge is seeking robust and...

What is a Footing Drain? A discussion about sump pumps must first start with footing drains. A footing drain or foundation drain is a system of perforated pipes beneath a basement foundation. The footing drain pipes are designed to keep groundwater from seeping into...

If you work in the water resources industry, you are bound to come across inflow and infiltration analysis in sewers. Engineers who work with these systems have developed extensive processes and jargon for evaluating inflow and infiltration from flow metering data....

You might often hear the terms "diurnal flow" or "diurnal pattern" when referring to water or sewer system flows. This post provides a short overview of what those terms mean and how they are derived from flow measurements. Diurnal Pattern Defined For starters, let's...

Seeking a commitment is seemingly a simple task. A manager asks a staff member to do something, and if they agree, a commitment has been made. But embedded in that simple task are several key elements that make a good commitment. These elements are diagramed in the...

What is pressure? For those of us in the water resources field, it is obvious from our everyday work and experience. But there are some nuances and details about pressure that are important to understand. In this post, I will cover the basic concepts of pressure,...

H2Ometrics uses several standard units for measuring flow, depth, velocity, pressure, temperature and volume. I thought I would share the conversions between the units in this post. The conversion table at the bottom of this post is a good reference on converting...
