DISEÑO DE TANQUES DE TORMENTAS EN ZONAS SEMIÁRIDAS: CASO DE ESTUDIO EN LA REGIÓN DE MURCIA

Abstract

Semi-arid areas are characterized by a climate with scarce and torrential rain events, with the Region of Murcia being a clear example. This situation has conditioned the design of stormwater detention tanks from the first one built in the 1980s in that territory, when it already had basic functions as rolling runoff that contributed to the general ovoid unitary system, but also the reuse of the water by the irrigators of the Campo de Cartagena. Currently 27 stormwater detention tanks have been executed throughout the Region. For the design the high levels of contaminants in the first water washes with periods of time between rains, the need to reuse all the waters, the conditions of the end receivers especially sensitive and protected and integration into the overall system of sanitation and exploitation of wastewater treatment have all been taken into account. In this paper an inventory of stormwater detention tanks is presented for the Region of Murcia with their design features and establishing common parameters regarding the impermeable surface, with the total area concerned, the buildability and economic viability.
