The province of Huelva has a significant amount of raw water transport and distribution infrastructure, equipped with electromechanical elements whose constant maintenance is necessary to ensure the supply that society demands. It is undoubtedly a vital artery for the provincial economy by supplying not only the vast majority of the population, but also the chemical polo industry and much of the agricultural production in Huelan irrigated community.

It is therefore essential to have a system for the maintenance, maintenance and repair of these infrastructures, since a failure of these infrastructures in sensitive places could cause extremely serious damage, even collapsing the agricultural and industrial activity of the province and to desupply drinking water to the population ( including the capital).
