On 24 October, seventeen parties \u2013 from Zeeland to Groningen \u2013 signed a declaration of intent through which COASTAR will embark on a new phase. The knowledge programme, which makes an important contribution to a robust freshwater provision in low-lying areas of the Netherlands, is to develop into a network, within which the parties collaborate in learning, implementing and upscaling.<\/p>\n<\/div>\n

The shared ambition of water authorities, municipalities, drinking water utilities, greenhouse horticulture, business and knowledge institutes is clear. By signing the declaration of intent<\/a>, these parties commit themselves to the further development and implementation of COASTAR<\/a>, the robust provision of freshwater through the smart use of the subsurface.<\/p>\n

Subsurface for provision of freshwater<\/h2>\n

The subsurface can make an important contribution to a robust freshwater provision in low-lying areas of the Netherlands. Under the motto \u2018saline at bay, fresh on hand\u2019, partners from South-Holland to Groningen have further elaborated and tested concepts and techniques over the last few years. Examples include the extraction and use of brackish groundwater and the subsurface storage of surplus freshwater. This effort built upon the decades of experience in managed aquifer recharge in the Dutch water supply dunes and recent, small to medium-sized aquifer storage applications in agriculture and horticulture, as well as in the city.<\/p>\n

Research and field trials<\/h2>\n

COASTAR is dedicated to a structural and strategic application of these concepts by means of research and field trials. Klaasjan Raat, researcher and programme manager at KWR Water Research Institute, was involved with COASTAR from its very beginning in 2016. He looks back with pride on what has been accomplished since then: \u2018COASTAR solutions have now been implemented at numerous sites all along the Dutch coast, in both pilots and full-scale<\/a>. They are contributing to a robust water provision for drinking water, horticulture and industry, and to water reuse in the city.\u2019<\/p>\n

2040: Netherlands resilient to freshwater shortages<\/h2>\n

The COASTAR examples offer prospects for solving (fresh)water demand issues. In a panel discussion, directors and managers stressed that upscaling was the next logical step. To accelerate this process, more than 20 parties will be collaborating over the next three years in the COASTAR network. The network brings together business, public authorities and knowledge institutions from Zeeland to Groningen. Ida de Groot-Wallast from the Deltares knowledge institute: \u2018We are working jointly on organising knowledge sharing between the different pilots, regions and organisations. We contribute to the agenda-setting and anchoring of knowledge and experience. We also provide guidance on follow-up initiatives and contribute to international collaboration. In this way we work towards realising our shared ambition: 2040, a Netherlands that is resilient to freshwater shortages through the full exploitation of subsurface opportunities.\u2019<\/p>\n

COASTAR in practice<\/h2>\n

During the COASTAR symposium on 24 October, which was opened by the Delta Programme Commissioner Peter Glas, several practical examples were reviewed.<\/p>\n
