NAWAMED: how the Cost-Benefit Analysis can be an important decision-making tool for the economic feasibility assessment of investments in Malta
The uptake of Non-Conventional Water Resources (NCWR) to help meeting the challenge of water scarcity in the Mediterranean area is strongly connected to the adoption of the emerging technologies for Water Demand Management (WDM) currently available on the market. WDM is a tool allowing water supply augmentation combining highly selective exploitation of new water supplies and use optimisation of existing water supplies. However, to replicate and increase the adoption of such technologies, a Cost-Benefit Analysis (CBA) on such interventions needs to be undertaken within different Mediterranean context to offer the best return for the society rather than possible alternatives.
These were the main topics addressed during the 3rd and 4th National Stakeholder Meeting organised by the Energy and Water Agency (EWA) on the 24th October 2022. The meeting focused on innovative, nature-based, and low-cost treatment solutions to change urban and domestic water management by replacing the use of potable water with non-conventional water in Mediterranean countries.
The National Stakeholders Meeting brought together policymakers, professionals and technical experts from the Private, Public and University sectors playing an active role in dealing with sustainable water management responses and issues in Malta. In fact, it was an occasion to participative discuss CBA as an important decision-making tool for the economic feasibility assessment of public/private investments, and the challenges for the promotion of WDM and NCWR within the MED regional context.
During the event, EWA presented the work activities currently ongoing under the MEDWAYCAP project - also financed and belonging to the “water cluster” of ENI CBC MED projects - aiming at facilitating the promotion of best practices on treated wastewater reuse as a non-conventional water resource both at urban and rural levels.
