Generally speaking, the earth is covered by 70% water. However, we only get 0.5% for human consumption, so it is a limited resource. This percentage is alarming because it is a fundamental good for human development and social development. The region of Ica, Peru presents projections of population growth, this department will reach its maximum population in the year 2030, which means that it is one of the departments with the greatest water deficit. This research sought to replace the excessive use of drinking water for the production of concrete with treated wastewater from the PTAR Aclara del C.C. In addition to this, a bacterial additive (Bacillus subtilis) was added at a concentration of 109 cells per milliliter and Calcium Lacto as a food source. This is to improve the physical and mechanical properties of the concrete. Three concrete mixtures (drinking water, wastewater and wastewater plus bacteria) in fresh and hardened state were prepared and evaluated. Slump tests were carried out according to NTP 339.035 and compression tests according to NTP 339.034, which were compared with the standard concrete at 7, 14 and 28 days with increases of 28%, 14%, 24% respectively. Then, the bending test was evaluated at 28 days under NTP 339.078 with an increase of 2%. Likewise, it was confirmed that the permeability of the element is reduced according to NTC 4483, and finally the economic viability of the three mixtures was evaluatedKeywords: Bacterium SUBTILIS; Waste treated water, PTAR; Calcium carbonate; Compressive strength; Calcium lactate.
