Saving water by returning to a constant water supply in Chihuahua

ABSTRACT

A sustainable drinking water system is essential to ensure the availability of water. Efficient management is developed by maintaining a positive and continuous pressure. However, in developing countries, the conception is that a constant water supply is unsustainable and the preferred alternative is to modify to an intermittent water supply. In this paper, a methodology for gradually transforming several sectors to a constant supply to decrease the quantity of water supplied is developed. Network sectorization and pressure management were achieved, indicating that the operation of 19% of the households under this methodology generates 24% of the water-saving of the city.
