Improve the reliability and effectiveness of alternative water resources supply systems and technologies


The search for affordable, acceptable and reliable solutions is today a common challenge for water supply planners.
Assessments and recommendations of how alternative water supply sources and infrastructures can relate to existing water utility regimes remain unexplored and there is a need to explore how the regulations around these centralized regimes can support infrastructure diversification.
The objective of this action is to improve the sustainability of various alternative water supply resources in the context of climate change and water scarcity adaptation.

Detailed Call Description

To achieve the objective the following issues should be addressed:

  • Improve the efficiency, reliability and cost-effectiveness and sustainable design of a wide range of alternative water solutions (e.g., rainwater harvesting, storm water, water reclamation and reuse , brackish and sea water desalination, aquifer recharge).
  • Assess the interaction between choices of the various alternative water supply technologies with the infrastructure design and development, the scale of operation and the water-energy interactions.
  • Assess various alternative water solutions with regards to their potential their innovation, climate mitigation and adaptation and their environmental and health impacts. Explore the potential of digital technologies for appropriate data collection and integration. Attention should be given to reducing the negative impacts of infrastructures to increase water supply in water-scarce areas as well as reducing water demand (rebound effect).
  • Develop a comprehensive framework or guidance tool for selecting specific technologies and management strategies for different water scarcity situations that can be adapted on a case-by-case basis and with a view of developing large-scale deployment strategies, in line with the requirements of the Water Framework Directive.
  • Assess the critical factors that hinder the public acceptance of alternative water resources and identify measures and actions (e.g., policy actions, marketing interventions) to encourage their acceptance.
