GEOGRAPHICAL INFORMATION SYSTEMS AS A TOOL FOR OUTLINING WATER PIPELINES

This paper presents an alternative assesment for designing raw water pipelines, for Sincelejo city, Colombia. Magdalena, Sinú and San Jorge rivers were taken as supply sources. Outline of each alternative was carried out using geographic information systems and a digital elevation model. Height profiles were obtained. It was determined that the shortest alternative is the Lorica-Sincelejo route (catchment in the Sinu river), followed by the La Jegua-Sincelejo route (catchment in the San Jorge river) and finally, Magangué-Sincelejo (catchment in the Magdalena river). Nonetheless, for topographic and source quality reasons, the best alternative is the one that takes the Magdalena River as a water supply.
