    Optimización del sistema de distribución de agua potable del barrio Mariscal Sucre Los Puentes, parroquia Saquisilí, cantón Saquisilí, provincia de Cotopaxi
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Civil, 2024-08) Calvopiña Tenorio, Cristian Andrés; Peñafiel Valla, Lourdes Gabriela
    Currently, the SDAP of the town is nearing the end of its 30 years design period. This has caused the system to present deficiencies and deterioration, causing overpressure and leaks, compromising the quality, quantity and continuity of the water supply. In addition, population growth and expansion have generated a deficient distribution of the network. Therefore, a proposal was developed to guarantee efficient use of the resource by improving and optimizing the system. This began with a comprehensive evaluation of the network, technically analyzing its physical condition by recording technical and hydraulic data sheets using a pressure gauge to measure pressure efficiency. The population register was updated by means of surveys to diagnose overcrowding, socioeconomic and sanitary conditions. Subsequently, a topographic survey was carried out using the photogrammetry technique. After data collection, the infrastructure was modeled and the system was analyzed using simulation software under static and dynamic conditions. The critical scenario of maximum hourly consumption was considered and the characteristic consumption pattern of the area was determined. The results indicated the need for a complete redesign. The improvement proposal contains the diagnosis of the current deficiencies, design of a system to meet future needs for the 30 years period, implementation of water quality improvements, optimization of the hydraulic parameters of the network, and cost-effective solutions.

    Análisis de recubrimientos anticorrosivos aplicados a los aceros Q235B y su incidencia en la tasa de corrosión, en el sistema de agua potable de la ciudad de Riobamba provincia de Chimborazo
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica. Maestría en Mecánica Mención Diseño, 2020) Amancha Torres, Hugo Fabián; Paredes Robalino, María Belén
    The investigation studied several anticorrosive coatings applied to Q235 steel, and the effects of the corrosion rate with the help of the salt spray chamber. The applied coatings are products known in the market and are AWWA C210 / 92 certified epoxy-food grade; because the pipe is used in the Drinking Water System of the City of Riobamba. The samples to be analyzed contain three different types of substrate cleaning prior to coating application and two types of coating application. For the present study, we will refer to the ASTM B117 standards, which details the necessary guidelines for accelerated corrosion tests in a salt spray chamber. According to ASTM D610, the degree of corrosion presented by the samples was indicated. And based on the ASTM G1 standard, the corrosion rate of each specimen was calculated. This analysis helped us compare and establish the best corrosion protection methods for Q235B carbon steel. Which are: UHS Duraplate - Bristle Blaster - Spraying and UHS Duraplate - Mechanical - Spraying with corrosion rate of 0.0205 mm / year.
