One of the most constant problems in the world is limited sanitation and supply of water for productive activities and human consumption. According to the United Nations Development Programme (UNDP), lack of water affects more than 40% of the world population. Additionally, it is necessary to point out that 844 million people do not have drinking water services, and that 80% of wastewater is led to waterways without the appropriate measures or treatment.
All that, affects the development of rainwater catchment systems for domestic and productive usage, specially for families in vulnerable situation and productive units in low and medium scale.
