Coefficient of Variation of Drinking Water Networks in Residential Urban Complexes

Abstract

The objective of this paper is to establish a real value of daily and hourly variation coefficients for the design of drinking water networks. Determining the real daily K1 and hourly K2 coefficients of variation of different residential urban complexes, can constitute a reference for the design of future constructions. To be able to size drinking water networks, it is important to know the magnitude of variations in the volume of water that exists and the demands of the population, as the water consumption depends on various conditions and aspects such as: climate, socioeconomic factors population, and for future designs, the global Covid 19 pandemic. The study area will take place in Ecuador, located in the Guayas Province, The Daule city, specifically in the residential urban complexes and called citadels, in the Brillante stage in La Joya and Estelar stage in Villaclub. The macro water meter reading was recorded, 3 days a week, 24 hours a day, in each citadel, then, information was obtained from real water payroll to calculate the coefficients and the impact of the diameter was also calculated with the formula of Hazen Williams. Finally, some real values of coefficients, are not within the range established by current regulations.
