Ductile iron pipe for drinking water mains has stronger walls allowing a larger inside diameter reducing friction and thus saving energy. According to St. Cloud’s Pumping Cost Study (July 2014), the city's use of ductile iron pipe (certified under the SMaRT standard ) results in an annual savings of $210,530 compared to competing pipe, measuring power cost, pump efficiency, and head loss.
