Abstract
Developed and crafted in Madagascar, the Raseta pump is a novel hydraulic ram (hydram) pump using a springs system. It operates differently from other pumps by the exclusive use of water energy due to the water hammer phenomenon induced by the sudden stop of the water flow. The present study initiates the investigation of the environmental impacts of this new type of hydram pump through a life cycle analysis using OpenLCA 1.8. It was found that, when operating in a small-scale water pumping system, the choice of the pump supply pipe material has small differences of environmental impacts, whether the material is made of steel or polyvinyl chloride (PVC). Moreover, compared to a solar pump for the same pumping flow rate, the use of the Raseta pump is more environmentally friendly and less harmful to human health. However, the actual advantageous utilization of such a system needs further studies such as social and techno-economic analysis.
