The data to estimate crop evapotranspiration using the FAO 56 Penman-Monteith method were obtained from a meteorological station installed inside the protected environment.Results The irrigation levels and the interaction with the concentrations of treated domestic wastewater significantly influenced the stem diameter, height and number of bean leaves at a level of 1%, while the concentrations did not significantly influence the number of leaves.Conclusion The treated domestic wastewater contained enough nutrients to meet the nutritional needs of the bean crop in relation to the treatment that received only water from the supply system. The use of treated domestic wastewater may constitute an alternative to save quality water in the growing of bean.   Highlights Domestic wastewater treated reduces the use of better quality water in agriculture. Reduction of environmental impact may be possible by using wastewater in agriculture. Domestic wastewater treated in bean growing may be a source of nutrients. Valuable support for future research related to crops yield with wastewater.
