ABCD strategic planning process Martijn Schiphouwer Lennart Swinkels
System • System: Scheldt Estuary Belgium/Netherlands • Sub system: The Rupel river system, a tributary of the Scheldt • Untreated waste water from the Brussels region affects oxygen levels and biodiversity • The Netherlands: all municipal water goes to waste water treatment plants • In a sustainable river system, release of harmful substances does not exceed the carrying capacity
Vision • A balanced Rupel river system in terms of waste water disposal and water quality. This will lead to a less polluted Scheldt system with a higher biodiversity.
System condition analyses • SC2: Unacceptable concentrations of substances produced by society => we have to eliminate our contribution to the progressive buildup of chemicals and compounds produced by societyin the environment • Organic pollution of the Rupel river system is still of unacceptable proportion, biodiversity is very low
Significant areas • The biggest challenge is to have sustainable waste water infrastructure for the total Rupel watershed • Current treatment capacity has to improve • More sewerage systems must be connected to treatment plants
Creative solutions • Optimalisation and expansion of waste water infrastructure
Decide on priorities Short term actions • Create awareness amongst industrial and domestic water users • Connect the largest unconnected urban areas to the main sewage treatment plant • Upscale treatment facilities Long term actions • All waste water to treatment plant • Building of new treatment plants • Implement strict laws concerning waste water discharge • Important stakeholders: Province, Aquafin, water users and VMM • Polluter pays principle, awareness of all parties, participation
