Energy savings can be obtained in several ways, but before manufacturers turn to hydraulic optimisation of units or apply new electrical drives or powerful control systems, they should look at the dimensions of the pipelines and make sure they get the duty point specifications right. This can be done with the aid of web-based tools from Vogel Software.

Increasingly, cities and low-lying areas are at risk of sewer overflow from extreme rainfall. Stormwater tanks can help reduce the impact of extreme climatic events by holding back excess stormwater and contaminants. This protects the environment and makes possible the intelligent management of stormwater flows, resulting in savings on infrastructure investments. Now Grundfos has developed a handbook informing engineers about tank design and optimisation.
