CONTRIBUTION OF GIS IN SELECTING THE FAVORABLE SITE FOR THE LOCATION OF THE STATION PURIFYING WASTEWATER OF AZROU CITY (MIDDLE ATLAS, MOROCCO)
Journal Title: Larhyss Journal - Year 2015, Vol 21, Issue 21
Abstract
Domestic wastewaters from the Azrou city are released into the environment without any treatment. Indeed, an initial rejection is close to neighborhoods Boumeloul, Hay Tabadlit and Hay Arz, a second in the middle of neighborhoods Tit H'sain and Kachla and a third discharge upstream of the source Ain Aghbal. These waters are contaminated and polluted directly reused in irrigation plots with high agricultural activities downstream of the city. They constitute a negative impact on the environment and can cause disease in both consumers in farm workers. Solving this problem requires the establishment of a wastewater treatment plant wastewater to their safe reuse in agriculture. The main objective of this work is the choice of suitable sites for the establishment of a treatment plant for domestic wastewater for Azrou city. The procedure to follow is based on the use of Geographic Information Systems (GIS). The results have yielded different thematic maps according to well - defined criteria. The overlay raster layers different criteria led to the selection of five areas with favorable site which No.1, located in Ait Haddou Ouqassou is highly favorable, given its proximity to the road network, the power grid and water system. The final assessment is effective only when it takes into account the views of stakeholders (politicians, managers, administrators, industrialists, environmentalists, soil scientists, hydrologists, hydrogeologists, geologists, urban planners). The results confirm that the Geographic Information Systems are powerful tools of spatial analysis to provide valuable assistance in decision making, planning and land management.
