The SUBSOL - bringing coastal SUBsurface water SOLutions to the market - project concludes with a final seminar on coastal water supply and reuse on Wednesday August 29 and a site visit to the ASR reuse facility Dinteloord on Thursday August 30. The program is open for businesses, policy makers, end users, researchers and other stakeholders dealing with freshwater supply in coastal areas.


The potential role of treated wastewater reuse as an alternative source of water supply is well acknowledged within European and national strategies. Water reuse is a top priority area in the Strategic Implementation Plan of the European Innovation Partnership on Water, and recently the European Commission has proposed new rules to stimulate and facilitate water reuse for agricultural irrigation. The subsurface can facilitate water reuse, by balancing the availability of reuse water with times of water demand after subsurface storage, and by improving the quality of the water through soil passage. Two of the SUBSOL replication sites indeed use treated wastewater as a water source.

The seminar brings together reuse experiences from the SUBSOL project, the European Union’s policies and reuse agenda, and experiences from end-users within and outside of Europe. Together we will sketch the prospects for robust future water supply and water reuse in coastal areas, contributing to the agenda for research, policy development and investments in the next decade.
