An inclusive culture that engages women in the design, operation, and maintenance of water and sanitation systems leads to better responsiveness and customer satisfaction. As satisfaction increases, so does willingness to pay for services and maintenance of water systems, which is key to sustainability. Its targets 6.1 and 6.2 are measurable by access to safely managed drinking water and sanitation services, coupled with hygiene promotion and an end to open defecation. Special attention is paid to gender and social inclusion, which brings sustainability into focus. Other targets respond to the environmental considerations and needs, along with a focus on international cooperation and capacity-building support to developing countries in water and sanitation-related activities and programmes.
