A Value Engineering Analysis of Head Loss in Pumping Mains

With net zero carbon emissions targets approaching over the next 20 to 30 years, water industry must act now develop energy efficient techniques and designs reduce footprint of utility providers. There is also potential for significant therefore financial savings be realised from adoption more approaches. Water providers account a proportion national electricity consumption. The purpose this research determine if, long term, opting larger diameter pipe at design stage can lead when considering pumping mains. Pumping mains are widely used throughout wastewater where gravity solution not possible. 72 hypothetical main scenarios were analysed term environmental impact each was assessed. It found across all that capable delivering same rate flow smaller pipes much reduced velocity requiring power. concluded pumped diameters ultimately cost effective selected in favour otherwise identical scenarios.
