Diseño hidrosanitario de un edificio de tres pisos ubicado en la ciudad de Santa Rosa, provincia de El Oro.

Abstract

In this practical work, the objective was to elaborate the hydrosanitary design for a 3-story building, in accordance with Chapter 16 – NHE Water Hydrosanitary Standard NEC-11. The building is located in the center of the city of Santa Rosa, on Cuenca and Filomeno Pesantez streets, where pressure readings of 3 mca were made, a pressure lower than that required by the standard, for which it was decided to implement a traditional indirect system. , this system consists of a tank, a pump and an elevated tank. The calculation of the required amount was made considering the type of building, from which 33939.1 liters/day were obtained. The cistern and elevated tank were sized for 60 and 40% of the supply volume, respectively, obtaining a cistern with a storage capacity of 2.85 m3 and the elevated tank of 1.5 m3. In order to know which was the ideal pump, the calculation of minor and friction losses was carried out for the suction and impulsion system. According to the system curve, a 0.7 HP pump was selected. The corresponding plans were made according to the results of the drinking water networks where diameters of 1 1/4 and ¾ inches were placed, for red water served, diameters of 2 and 4 inches and four downspouts were obtained. For rainwater, 3-inch diameters were used and 2 downspouts were placed. He also made the isometry of the water network and the pumping system used.
