Demo site 3
Water reuse sector:
Agricultural water reuse
Wadden Region, Netherlands
Leading Partners
Background
The demo site is located in one of the islands in the Wadden Sea – Texel, in a polder that hosts the world’s largest contiguous flower bulb production area, as well as other crops such as sugar beet and potatoes.
The site employs an ASR- Aquifer Storage and Recovery system, collecting water from a tile drainage water network on a 10-ha agricultural parcel.
The system diverts drainage typically meant for run off into a Slow Sand Filtration (SSF) in combination with Granular Activated Carbon (GAC) through two injection wells into a confined sandy aquifer. During dry periods, water is pumped up for irrigation purposes.
Expected Benefits
Preserve aquifer water quality by controlling nutrients and pesticides in the tile drainage water.
Enhance the cost-effectiveness, optimization, and minimal footprint of the large-scale ASR – Aquifer Storage and Recovery system.
Increase the reliability and acceptance of Managed Aquifer Recharge using tile drainage water within the agricultural and water sectors, contributing to its overall feasibility and sustainability.
Promote farmer engagement to support the necessity of Managed Aquifer Recharge, investment in these systems, and proper operation to meet potentially stricter future water quality standards.
