Item Diseño del Plan Tarifario para la Junta Administradora de Agua Potable de Chibuleo San Francisco, parroquia Juan Benigno Vela del cantón Ambato, basado en el análisis hidráulico técnico y económico del sistema de abastecimiento de agua potable(Universidad Técnica de Ambato-Facultad de Ingeniería Civil y Mecánica-Maestría Hidráulica Con Mención en Obras Hidráulicas, 2026-08-18) Muyulema Muyulema Danny Germán; Castro Solórzano Fidel Alberto; Universidad Técnica de Ambato-Facultad de Ingeniería Civil y Mecánica-Maestría Hidráulica Con Mención en Obras HidráulicasThis research was conducted at the Drinking Water Management Board of Chibuleo San Francisco, located in the Juan Benigno Vela parish, Ambato canton. It arose from the need for a technically supported tariff scheme to guarantee the economic, operational, and technical sustainability of the water supply system. The general objective was to design a tariff plan based on the hydraulic, technical, and economic analysis of the system. The methodology combined field, descriptive, and analytical research through the collection of operational data, user surveys, consumption pattern analysis, infrastructure evaluation, water balance, determination of water losses, and the structuring of administrative, operational, and investment costs. The results showed an average water allowance of 83.02 L/hab/day, a maximum hourly variation coefficient of 1.96, and a daily variation coefficient of 1.31, identifying critical demand periods that condition network operations. Furthermore, a high service coverage was determined, with 95% of users receiving a permanent supply, and the need to strengthen loss control mechanisms and optimize the management of non-revenue water was identified. The economic analysis established the real costs of service provision and incorporated criteria of efficiency, solidarity, and cost recovery. The proposed tariff structure, organized by categories and consumption blocks, demonstrated financial viability, ensuring the coverage of administration, operation, maintenance, and investment costs. It was concluded that integrating the hydraulic diagnosis with the economic evaluation constitutes an effective tool to improve community drinking water management, promote the efficient use of the resource, and ensure system sustainability, while also serving as a replicable methodology for other rural supply systems.Item Análisis de la valoración económica de las tarifas de agua potable de la Junta de Rubén Terán de la ciudad de Latacunga, Provincia de Cotopaxi, Ecuador.(Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica. Maestría en Hidráulica con mención en Obras Hidráulicas., 2025) Alpusig Jacho Luis Gonzalo; Castro Solorzano Fidel AlbertoThis study addressed the economic valuation of drinking water tariffs in the Junta de Agua Potable de Rubén Terán, located in the city of Latacunga, province of Cotopaxi, Ecuador. The main purpose was to develop a fair, equitable and sustainable tariff plan, based on a detailed analysis of the real costs of production, treatment and distribution of water resources. The project arose from the need to update a tariff scheme that historically has not reflected real operating costs, which has compromised the financial sustainability of the system. The research was developed under a mixed approach, combining quantitative, qualitative and descriptive methods. Through field measurements, situational analysis, user surveys and documentary review, key information was gathered on the current state of the infrastructure, citizen perception, the level of losses in the network and the existing cost structure. The average inflow to the water treatment plant was established at 18.58 liters per second, using the floating object method. This data was essential for projecting demand and sizing the proposed tariff system. From the financial point of view, one of the main findings was the calculation of the Net Present Value (NPV), which reached a positive value of US$339.894,07 over a 10-year evaluation horizon, starting from an initial investment of US$64.879,50. This result indicates considerable profitability and evidences the economic viability of the project. The positive NPV demonstrates that, by applying a tariff scheme adjusted to xx real costs, not only is the recovery of the investment guaranteed, but also a significant surplus that can be used for system improvements and maintenance. The cost analysis considered three categories: administrative costs, operating and maintenance costs, and investment costs. The most significant costs were identified as being related to infrastructure maintenance and network losses, attributable in part to the lack of micro-metering, clandestine connections and an aging infrastructure. There was also evidence of a billing and collection gap that directly affects the Board's operational capacity. Based on these findings, a tariff plan was designed with a block approach by user category (residential and non-residential), following the guidelines of the Water Regulation and Control Agency (ARCA). For the residential category, four consumption blocks were established: basic (0-10 m³), medium (11-30 m³), high (31- 40 m³) and excessive (over 40 m³); and for the non-residential category, three blocks: basic (0-30 m³), medium (31-50 m³) and high (over 50 m³). This scheme makes it possible to assign progressive tariffs, encouraging responsible consumption and discouraging excessive use of the resource. Among the main conclusions of the study is that the current tariff structure does not cover the real costs of the service, which puts its sustainability at risk. The lack of micro-metering prevents equitable charging and contributes to the waste of the resource. It was concluded that the implementation of a new tariff scheme, based on actual consumption and technical costs, is essential to ensure the financial and operational viability of the system. In addition, it was recommended that internal governance be strengthened, citizen participation channels be improved, and education on efficient water use be reinforced. In summary, the study provided the technical and financial tools necessary for a tariff restructuring based on criteria of equity, sustainability and efficiency, to ensure access to drinking water as a human right and a vital resource for community development
