In Holguin, only 50% of supplied water is treated into drinking water. Once treated, the water is pumped by diesel-fueled pumps into tanks, which are then routed to distribution centers or directly to homes. Ensuring a regular water supply to rural areas represents an even greater task and deliveries can be intermittent.

The Mangrove Foundation, alongside Solidarité-Luxembourg Cuba, seeks to address this challenge by installing local photovoltaic chlorinators in rural zones so that a safe water supply can be ensured for local populations, namely in the Bàguanos municipality. Four photovoltaic energy pumps will be installed, providing safe drinking water for up to 500 people.
