UNESCO/IHE - Multi-objective Photo-activated sludge process rehabilitation of sewers
UNESCO-IHE has developed a decision support system that uses a new approach for rehabilitation of urban drainage infrastructure assets. This new approach is imbedded within the OPTimal REhabilitation of Sewer Systems software (OPTRESS) and it can be used to derive optimal sets of either wastewater or stormwater rehabilitation measures with respect to the given levels of service, total lifecycle cost of new assets and the existing asset condition. The tool uses full-fledged multi-criteria global evolutionary optimisation techniques in combination with hydrodynamic models of drainage systems and floodplains. It enables the identification of solutions that are not only cost-effective but also optimal in relation to any of the desired criteria.
