    The present project aims to implement two alternative techniques capable of purifying and removing pollutants present in the gray water coming from the kitchen sink of a singlefamily home, in order to analyze whether the water treated by these systems is capable of being reused. First, the sector to work was chosen: Area of Santa Fe, Atahualpa Parish, Ambato district, Tungurahua Province. Consequently, a survey was carried out for the inhabitants of the single-family dwellings (MIDUVI) in the chosen sector, where questions were useful for the effectiveness of the design of the proposed alternatives. The first technique is based on a wastewater treatment system composed mainly of a grease trap and a FAFA filter (Up flow Anaerobic Filter); whose designs, construction and operation have been determined based on the Pan-American Health Organization. (OPS) and the Salvadoran Association of Engineers and Architects (ASIA); as an experimental part we used materials such as: crushed lava rock (diameter: 5 cm), rounded rock (diameter: 5 to 10 cm - regulated in the OPS) and crushed moringa seed. This treatment system will include a storage tank for raw gray water, and a storage tank for treated water when leaving the system. The second alternative consists of a treatment system proposed by Katukiza, it is a series filter of silica sand (diatoms) and crushed lava rock (diameter: 0.5 - 1 cm), with gravel bases under each material (diameter: 1 cm); Its design and construction is easier and less expensive, this treatment system will include a storage tank for raw gray water, and a storage tank for treated water leaving the system. The results of the raw water sampling, together with the results of the water treated by alternative 1 and 2, were analysed in the EMAPA quality control laboratory (SAE accreditation), which showed that both alternative 1 and 2 have been able to remove appreciable amounts of oils and fats, BOD5, COD, floating material, nitrites, pH and sulphates; however, alternative 2 showed a better performance.
