    The present technical work has the purpose of provide information on the physical and chemical properties of substances of Ecuadorian origin for water treatment and the presentation of plans for a permeability measurement system. In the first place, a bibliographic research of the properties of actived carbon, limestone and peat because of these substances have been used for the water treatmet by filtration thanks their efficiency and lower cost in relation to conventional treatment systems such as screening and sedimentation. Laboratory tests were carried out following their respective regulations, which helped us to determine the granulometry, maximum nominal size of particles, coefficient of uniformity, coefficient of curvature, coefficient of compactness, porosity, sphericity and permeability. For the preparation of the permeameter plans, the AASHTO T 215 – 70 standard was followed, wich refers to permeability of granular soils, and the Autocad 2019 program was used both for presentation of plans and 3D modeling.
