| Sumario: | [EN] The present Master Thesis Project has as main objective to design a unified network of collectors to the city of Peña Blanca, due to the fact that there is currently no system of wastewater and rainwater collection. Through the municipality of the city has obtained a first design of the drainage network, which has been the starting point for the diagnosis of the current situation. Subsequently is there will be two performances improvement to the initial network due to the new expansion areas. The first two chapters of this thesis present a general approach of the study area, detailing the most important aspects that characterize the city as be the location, climatology, social, economical, and demographic situation and in addition the studies that have been done up to now referring specifically to the issue of sanitation in the city. The third chapter shows the collection of baseline data and the hydraulic criteria proposed by the National Autonomous Service of Aqueducts and Sewer Systems of Honduras (SANAA), which were the guidelines for the diagnosis and the alternative approach of improvements. The fourth chapter refers to the method of calculation that was used to perform the mathematical simulation model that will represent the current and the future scenario of the sewerage network. The tool that has been used was Stormwater Management Model SWMM 5.1., which allows the joint evaluation of the urban runoff and wastewater through the introduction of hydrological and hydraulic parameters. The fifth chapter focuses on the analysis and diagnosis of the initial network of collectors. There were made several simulations in which was identified that the sewer collection system works in dry time under the introduction of wastewater, however when was introduce a design of a 20 years storm of two hours duration with intervals of 10 minutes the network collapses generating flood throughout the system. In the sixth and seventh chapter develops the stage of approaches to solutions which intend, according to the new expansion areas, propose two designs to the future network of collectos for the year 2035. The first proposal consists in the design of a single primary manifold that pretend to collect all the waters of the four sectors in which it was divided the city for then to be poured to a water treatment plant under the network. It was identified that the network worked in critical regime, this due to the topography of the network showed outstanding high producing speeds up to 14 m/s, so that its design was performed through the simulation tool HEC-RAS. The second proposal focuses on the design of stormwater tank developed basically with environmental criteria, with the objective of avoiding the dumping of pollutants to the receiving medium during rain events, i.e. retain the first runoff. These tanks are placed in the final part of each sector and its predimensioning was developed from a series of historical data of rainfall in the period 2010-2015 using the method of the ratio of events held, which establishes the relationship between the volume of each tank with respect to the total area of each basin and the efficiency possible. Finally in chapter eight presents the detail of economic estimation for each of the two proposals, where the choice of any of them for implementation will depend on the current needs of the city without leaving to one side the forecast future. |
