Resumen
This paper performs a study of the effect of roughness in sewerage networks located in areas of highland. Two case studies located in Bogotá, Colombia, are presented, which manages to analyse through tables and graphs the optimal trend relationship between cost and pipe roughness for high slope scenarios. This paper is presented as an extension study of "Optimal Sewer Network Design for Hilly Regions" proposed by professor Juan Saldarriaga, research engineer Juana Herrán and professor Pedro L.Iglesias-Rey. They presented a design method that includes drop manholes applied by graph theory to find the minimum cost and performing an energy dissipation role in order to comply the present restrictions established in the Colombian design regulations. The academic software Utopia is used, which adopts the mathematical and procedural principles established in the article "Sewer Network Layout Selection and Hydraulic Design Using a Mathematical Optimization Frmewok" authored by Natalia Duque, Daniel Duque, Andrés Aguilar and Juan Saldarriaga. The results obtained corroborate that the proposed methodology allows optimal sewer network design for hilly regions while complying with all hydraulic restrictions. Additionally, it allows to perform a criterion of the optimal materials in construction cost for a restricted range of slopes in mountainous areas.
