This 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.
Evaluación de la red vial en el área urbana de la parroquia Izamba de la nueva historia de Ambato, comprendida en la zona 30

In Ecuador, there are sectors whose road network is in poor condition due to neglected road maintenance processes. This leads to the deterioration and wear of the existing road network, primarily affecting its functionality, which is closely linked to the social and economic growth and development of a sector. Therefore, the evaluation of the urban road network in sectors such as the Izamba parish, located in Zone 30, is important for identifying areas that require some type of intervention through the application of preventive maintenance techniques that prevent the loss of the road structure and the additional costs associated with poor transportation and vehicle operation. To this end, activities such as topographic surveys using equipment such as drones and RTKs were carried out, in addition to vehicle traffic studies using the thirtieth-hour method, which employs manual vehicle counting. This was also complemented by a soil study, which included tests such as natural moisture content, particle size analysis, Atterberg limits, modified Proctor (method B), and CBR, primarily seeking to establish the properties and characteristics of the sample tested. In addition, the road network was evaluated using the PCI (Pavement Condition Index) method to assess the current condition of the road network and identify appropriate maintenance techniques based on the determined PCI value. Finally, the pavement design was developed based on the AASHTO-93 standard, and the reference budget was prepared. The road network evaluation was carried out on a total of eight roads, of which four are fully paved, three have paved and cobblestone sections, and one is entirely cobblestone. The results revealed 247 failures in both roads and sidewalks, of which 9 correspond to existing damage to the sidewalks and 5 are located in cobblestone streets. Furthermore, it was identified that patching and service connection failures occur most frequently, with corrugation and parabolic or sliding cracks being the least common failures.

The objective of this study was to evaluate automated sprinkler irrigation using moisture sensors in alfalfa crops within the Tunga project. The trial plot is located at coordinates X: 765,616 Y: 9,849,376. The proposal was to conduct soil studies, calibration of moisture sensors, statistical analysis of response variables, a water use efficiency analysis (kg/m3), and an economic analysis. For this study, an alfalfa plot with four replicates (1 m2 quadrants) for two moisture loss percentages (T1: 50% and T2: 75%) and a T3 (control) were used. The response variables were yield (kg/ha) for a total of two intercutting intervals and water consumption (m3) between cuts. The experimental design was a "Completely Randomized Design" (CRD) in 732 m2 experimental units with six pressure-regulated sprinklers for each treatment and an irrigation controller with two moisture sensors, one per treatment. The results of the soil analysis were: sandy loam texture, moisture content at field capacity (F.C.) 12.37%, moisture content at permanent wilting point 7.4% and apparent density 1.52 g / cc. The calculations defined that the Usable Water Layer (UWL) or the initial point for F.C. was 22.66 mm at 30 cm depth, thus, for the moisture losses of T1: 50% and T2: 75% the values were 11.33 and 5.67 mm, respectively and the calibrations of the moisture sensors responded to these values 22.66 mm or 15 centibars, 11.33 mm or 30-35 centibars and 5.67 mm or 60-65 centibars. The results of the Analysis of Variance (ANOVA-Turkey 5%) for the yield variable were T1 (2.07 kg/m2), T2 (2.08 kg/m2) and T3 (2.18 kg/m2), which are statistically similar. Water consumption of the control T3 (188.88 m3) was higher than T1 (169.19 m3) and T2 (161.22 m3). Humidity sensors, in addition to irrigation automation, were a strategic ally in saving water. In reference to water use efficiency, T1 was the most efficient with 22.63 Kg/m3, in second place is T2 with 22.55 Kg/m3 and T3 with 20.29 Kg/m3. The most economical treatments were T1 (USD 0.30/month) and T2 (USD 0.30/month), while T3 (USD 0.35/month) was the most expensive, in this sense, it is concluded that the use of water without controlling soil moisture generates waste and economic losses.
