Surrogate modeling for water reuse planning in complex water systems*

Integrated management of water reuse technologies and coordinated operations with other system components is fundamental to fully exploiting potential. Yet, these are primarily designed considering their individual efficiency more than possible synergies traditional practices. In this paper, we introduce a general-purpose framework that couples physical surrogate modelling optimal control methods support policy-makers in selecting robust efficient planning portfolios, integrating strategies loops. The developed for the case study Apulia Region, Southern Italy, characterised by presence complex distribution network multiple conflicting users across irrigation districts, industry, urban supply. addition, shares strategic reservoirs drought-prone area. Numerical computations, here performed historical period 2010-2019, can be directly applied consider future climatic scenarios (i.e., modification precipitation temperature patterns), socio-economic changes variation demand), technological innovation different strategies). This work represents first step towards enabling circular economy treatment-reuse technologies.
