In the SW delta, the agricultural sector is confronted with growing impacts of water shortage and salinization. The Province of Zeeland is aware of the negative influence on the socio-economic development. The agricultural sector (ZLTO) and municipalities (e.g. Schouwen-Duiveland) consider a reliable freshwater supply as one of the key issues for future development and sustainable growth. On a national level, strategies to reduce freshwater demand and increasing freshwater supply are being developed within the Delta Programme..
Our project's project’s main goal is to improve the use of existing fresh groundwater resources and create new freshwater reserves, thereby increasing regional self-sufficiency and reducing dependence on external freshwater supply. Research already takes place on theoretical feasibility of possible measures. Building on this knowledge, the research goals are:
- to investigate which measures actually 'work' ‘work’ in practice, and
- to analyse whether such measures are economically feasible.

The Drains2Buffer showcase involves the installation of drain tiles at a depth of 1.2 m below ground level, which is 0.5 m deeper than the current drainage depth, and the horizontal drain separation is reduced from 10 to 5 m. The new tile-drainage system allows the discharge of deeper and more saline groundwater from the mixing zone during rain events while the rainwater lens is growing by the recharge of infiltrated rainwater until a new equilibrium is reached.
The province of Zeeland, ZLTO, the Water Boards Scheldestromen and Brabantse Delta, the municipality Schouwen-Duiveland and STOWA all contribute to the project, from a financial contribution to inserting local expertise, arranging permits and taking care of small water management measures.
