This document describes the design of a sewerage and excreta treatment system for the community of Ardilla Urku in Napo, Ecuador, which lacks adequate sanitation infrastructure. The objective is to provide access to sanitation and ensure proper wastewater management. The design was based on information gathering and design standards, using a 20-year design period and EMAAP and INEN standards. For the design of the stormwater drainage system, the rational method was used to calculate the flow generated by the surface runoff of the drained area. A layer of contributing residential areas was generated and the area was calculated for each site using ArcGis software and satellite images. The results show that the proposed design is adequate to meet the needs of the community and improve the quality of life of its inhabitants, in addition to protecting public health and the environment.
