Improved water quality in coastal regions with sustainable aquifer storage


The quality of ground water in coastal regions can be particularly endangered by saltwater intrusion. This pollution creates shortages of potable water in many places, impacting negatively on both ecology and on human beings. In order to enable optimised management of water rescources, innovative subsurface water solutions have been developed and piloted in the Netherlands for several years. This approach has proven to be effective, sustainable and cost-efficient.

The technology is now being assessed in and adapted to different country contexts in the framework of SUBSOL. This project is designed as a multi-partner, international research endeavor as part of the European Union’s Horizon 2020 programme for research and innovation. SUBSOL seeks in particular to catalyse the market breakthrough of subsurface water solutions.

In the course of the project, the envisioned market uptake is being achieved through a variety of measures, including new pilots, the development of site-specific business cases, building decision-making support tools and conducting capacity building. These activities target the Mediterranean region and Western Europe, as well as the overseas markets in the US, Brazil, China and Vietnam. One key deliverable of the project is an online platform, constructed to share the project’s outcomes and link existing stakeholders and networks.

Within the international consortium, adelphi’s role lies in building a promotional strategy that systematically creates acceptance for and speeds up market uptake of subsurface water solutions. Once being completed, the approach is going to be replicable, allowing other small and medium sized enterprises in the water sector to utilize it in Europe and overseas.

adelphi conducts market scans to identify the most promising regions in the target countries. Such analyses include, among others, examining political and economic framework conditions of national and regional water markets. Building on these outcomes, recommendations are worked out to inform both policy-makers and technology providers regarding the uptake of subsurface water management solutions.
