The Lurín River is a source of water for the city of Lima; however, the dumping of domestic wastewater, the formation of dumps, in addition to long periods of drought, cause the deterioration of the water resource; therefore, in this study the DO, BOD, E.Coli, T, CE, SST, U and h were monitored in 8 points in the river, 4 in effluents from WWTPs and one in the return of the irrigation canal La Capilla, making a total of 13 monitoring points, covering 20km of the river, with 9 catchments from irrigation commissions distributed along the stretch. This information was used to calibrate the parameters of kdbo, kaire, kdos, VsDBO and kdec, in the two-dimensional numerical model Iber, obtaining values of 0,55 d-1, [4,84 d-1-80,65 d-1], 10 gO2 m-2d-1, 0 m d-1 y [1,49 d-1- 15,42 d-1], respectively, with efficiencies from "very good" to "satisfactory" with E values: 0.813, 0.959, 0.944 and 0.518 for OD, DBO5, E.Coli and T, respectively. The computational time in each simulation was 3 days, considering a discretization with a mesh with a resolution of 3, 5 and 7 m in the riverbed, riverbanks and plains, respectively. The greatest contamination is concentrated in the lower section, at the height of km 5 + 400, up to the Pan-American bridge, with July being the most critical month; therefore, a scenario is proposed in order to recover the river, which consists of the implementation of the PTAR Pachacámac and the optimization of the PTAR San Bartolo with discharge flows of 0.373 m3s-1 and 0.980 m3s-1, respectively, with concentrations of 4 mg l-1, 15 mg l-1 y 1000 NMP/100ml of the T, OD, DBO5 y E.Coli, respectively, which will allow the river to comply with the respective ECA
