Sectorización de coeficientes de diseño diarios y horarios para sistemas de agua potable en el Cantón Rumiñahui

Abstract

Urban growth demands precise planning of potable water systems. This research focuses on the Rumiñahui Canton, where key points for hydraulic design were evaluated. Historical consumption projections were analyzed. The objective was to establish peaking factors that optimize the efficiency and sustainability of water supply. This study assessed the K1 (maximum daily flow) and K2 (maximum hourly flow) magnification coefficients in three parishes of the Rumiñahui canton, comparing projected results until 2035 with the INEN 1575-1:2013 standard. The analysis used historical consumption and population data, applying exponential projection methods to estimate future water demand. The results show that K1 values generally remain below the minimum threshold of (1.3-1.5), with Sangolquí showing stable demand, San Pedro de Taboada showing slight increases, and San Rafael showing greater data dispersion. Regarding K2, San Pedro de Taboada exceeded the normative range (2.0–2.3) with values reaching up to 2.71, suggesting potential system overloads. Sangolquí showed a declining trend, while San Rafael remained above the normative limit in several years. The study concludes that while K1 values are within acceptable limits, K2 peaks present a growing risk to the sustainability of water systems. Recommendations include adjusting magnification coefficients to local conditions and implementing continuous monitoring to optimize operational strategies and mitigate demand peaks
