Lorgana and Botte irrigation district is an area of about 24,500 ha falling within the CBR area, which collectively manages 3,419 km2, including the Metropolitan City of Bologna. Irrigation in the area takes place through artificial channels and pressure pipelines that have the function of conveying water to the farms and collecting drainage water and discharging it into water bodies. It is an important agricultural area with main crops such as cereals, legumes and industrial crops. The selected area is of interest to the project because it is characterized by clear water inputs and outputs, the presence of a large area (1.300 ha) of wetlands, which have an important environmental function, and a total of 12 sewage treatment plants that discharge their effluents into the irrigation network.
The NEXUS focus for this DP will be exploiting water and energy conservation measures/approaches based on the real water balance, at district scale, considering all the water fluxes to/from the area including NBS for return flow treatment. Moreover, different factors influencing irrigation water quality will be considered.
