Abstract

Rural sectors such as the canton of Puerto-Quito, discharges its wastewater into natural resources, causing environmental, social and health problems, since a large part of its inhabitants consume water from these same resources. The methodology of this work was experimental and was based on the INEN norms for the processes and analysis of sampling and treatment and their results, using several treatments and identifying the best one by means of the Tukey test, the septic tank was sized according to the results obtained and the environmental impact that it will generate was evaluated by means of the importance matrix. The objective of this work was to carry out the treatment of domestic wastewater by means of a septic tank, for the purification of pollutants and the reinsertion of this water to the natural environment, complying with the current regulations of Ecuador. The best treatment to purify the pollutants and comply with the current standard was treatment 3 with 15 days of retention time, and for the design of the septic tank for 12 inhabitants was a height of 1.65m, a width of 2.50m and a length of 5m, in addition to the evaluation by matrix of importance for the implementation of the septic tank yielded low-moderate environmental impacts, making the project totally feasible.
