As part of an open programme, simple drinking water supply systems (called HVA systems, i.e. drilled wells, electric pumps, water storage tanks, distribution networks, public standpipes and some house connections) were financed in two phases in rural, electrified villages (1,000 to 4,000 inhabitants). The residual funds were used to provide sanitary facilities for health centres and schools. A total of 112 HVA systems were installed. The last HVA system was transferred in 2017. A complementary measure to raise awareness of hygiene and provide training for the construction and operation of the water supply and sanitation facilities was implemented.
