Water is fundamentally important for maintaining life on the planet, one of the activities that uses this resource the most is irrigation, so a study was carried out on the reuse of water in agriculture, aiming to make better use of water resources in a sustainable way. . The aim of the work was to evaluate the development of the Grass Brachiaria brizantha cv. BRS Piatã , irrigated with different concentrations of fish farming effluent. An experimental scheme was used in randomized blocks with subdivided plots, with the plots consisting of three treatments: T0 – (0% Wastewater), T1– (25% Wastewater), and T2 – (100% Wastewater). They were statistically analyzed using the SISVAR program using the Tukey test at 5% probability. The results were positive in T2 – (100% Wastewater), having a greater significant effect on parameters such as plant height, green mass, dry mass and root size, with the highest averages, but T1– (25% Wastewater) also had a positive influence, compared to the values of T0 – (0% Wastewater).

In addition to promoting human health and well-being, water has been used for the most diverse activities, for domestic and industrial use, energy production, agriculture and livestock.
Brazil has a large availability of fresh water in its territory, with an average volume of 257,790 m3 /s (considering the national territory plus the contribution area of the Amazon Basin beyond the border), representing a per capita of 47,042 m3. Hab./year (BERNARDI, 2003).
Currently, one of the major concerns refers to the quality of surface waters, which have been used as support for the elimination of waste produced by man. Water pollution problems are, for the most part, characterized by poorly planned urban, rural and industrial growth (PORRÉCA apud JABOTICABAL, 2007).
The use of fish farming effluent to irrigate plants reduces the costs of obtaining water, as well as the amount of chemical fertilizers needed for crops (Lima, 2010).
Kummer et al. (2012) state that the use of effluents in agriculture has grown considerably in recent years in many countries, including Brazil; however, all the positive and negative aspects of this technique have not yet been sufficiently studied, especially regarding the physical and chemical properties of the soil, absorption of nutrients by plants or their toxicity.
On many farms in Brazil, there is a considerable volume of wastewater that could be used for fertilization in various crops. The transportation and labor costs for applying this waste have led to the search for more economical alternatives, such as application via an irrigation system, as, depending on its origin, animal waste can contain 60 to 98% liquid. In the United States, the use of irrigation to apply liquid manure has grown since the beginning of the 1970s (DRUMOND et al., 2006).
