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.
