The Blackwell Group is a multidisciplinary engineering firm located in Virginia that performs work in the residential, commercial, and government sectors. Stormwater design and site grading are just a few of the many services that Blackwell Group offers. In a...
Pumps & Systems magazine had a good article recently on the need to calibrate pressure gauges. They pointed out that pressure gauges (and sensors) tend to lose accuracy over time; specifically, that gauges should be calibrated at a regular interval,...
Pressure zones are important but can be difficult to understand. OpenFlow WaterGEMS and OpenFlows WaterCAD makes creating and managing pressure zones easy....
In the blog A Multi-Species Decay Model to Support Cost-Effective Chlorination in Distribution Systems, a cost-effective chlorination strategy is defined as the least-cost combination of doses (locations and rates) that achieves effective chlorination for a given stable flow regime and...
Most hydraulic engineers would admit that the Darcy-Weisbach equation is the most theoretically correct equation for head loss in pipe flow. It is based on a force balance between the driving forces of pressure and gravity, offset by head loss...
Pretty much all well-run water utilities periodically develop a master plan. The plan looks out 20, 30, 40 years and tries to layout development in source, treatment, and distribution systems. Based on the best available demand forecast, pipes, tanks, and...
