#vidanaroca #cuidandodositio #agroecologia #fossaecologica #evapotranspiration In today's video we show you step by step how to make a septic tank by evapotranspiration. It is a system of treatment and reuse of nutrients from the effluent coming from the toilet through the anaerobic decomposition of organic matter, mineralization and absorption of nutrients and water, by the roots of the plants. Measurements of our project: Width: 2m Length: 2m Depth: 1.75m ATTENTION: The length of the septic tank follows the proportion of 1m per person, that is, a house with 4 people, the length should be 4m. In our project we chose 2m, because we will only be on the farm on weekends.
