Direct inline boosting (no suction sump) is very common and recommended for water distribution networks. The main benefits are energy savings and less possibility of potable water contamination.

In water transmission pipelines where two stage pumping is required typically to avoid high pressures, direct inline boosting can also be used, but is less common because of higher operational risks.  Water transmission typically involves high flow, high pressure, long pipelines, varying topography and surge protection devices.  Operating two pumping stations is series (direct inline boosting) needs a comprehensive and coordinated control philosophy to deal with specific operational situations such as a pump trip or total power failure in one of the pumping stations.
