Water Board Scheldt Streams

What Water Board Scheldt Streams does

Waterschap Scheldestromen is a Dutch regional water authority (waterschap) operating under public law in Zeeland province, Netherlands, headquartered in Middelburg. Established in 2012 through the merger of waterschappen Zeeuwse Eilanden, Zuid-Beveland, and Walcheren, the organization holds exclusive statutory responsibility for water safety, water quality, and water quantity management across the province. Its core operational assets include 424+ km of dikes and dunes inspected daily, 12,511 km of waterways, 4,000 km of rural roads and cycle paths with 125,000 trees, and 15 wastewater treatment plants — including the Walcheren Energiefabriek, which was converted in 2017-2018 for €9.7 million using anammox bacteria and struvite precipitation reactor technology to achieve 135% energy self-sufficiency.

The organization's service portfolio spans dike reinforcement under the national HWBP program (114 km planned through 2050, the largest dike program since the Delta Works), freshwater supply for agriculture in saline Zeeland (Tholen, Sint Philipsland, Reigerbergsche polder via Volkerak Zoommeer import), real-time water quality monitoring at 150+ measurement points, individual wastewater treatment (IBA) compliance management, groundwater management, and pharmaceutical residue reduction. Technology infrastructure includes a real-time water monitoring network (WaterInfo application) covering thousands of measurement points across 9,000+ polder areas, FRESHEM-NL helicopter electromagnetic surveys mapping freshwater-saltwater distribution up to 200m subsurface depth, and sludge processing via the SNB partnership (~44 million kg of Zeeland sludge annually). The organization also provides daily wastewater sampling to RIVM for national coronavirus surveillance.

Scheldestromen is funded entirely through statutory waterschapsbelastingen (watersysteemheffing, zuiveringsheffing, and a separate wegenheffing effective January 1, 2027), collected by Sabewa Zeeland from all residents, property owners, and businesses within its district — supplemented by permit fees and service charges. Customer segments span Zeeland households, agricultural landowners (with differentiated freshwater supply tariffs of 35%-50% of unbuilt rates), industrial water users, and institutional partners including RIVM, Evides water utility, Province of Zeeland, ZLTO, and cross-border Flemish authorities via the WIJ-Water Interreg project. Governance is provided by a dijkgraaf-led daily board, an algemene vergadering, and an independent Rekenkamer (audit chamber) established May 30, 2024.
