Ecosystem-based management strategies for urban wastewater systems (EcoMaWat)
Start date: Sep 1, 2011, End date: Oct 12, 2015 PROJECT  FINISHED 

Ecosystem-based management strategies for the urban wastewater system (UWWS) are needed for the successful implementation of Water Framework Directive. UWWS discharges should be dynamically regulated to not exceed the river waste treatment capacity. The overall aim of this project is to increase the knowledge about the interactions between UWWS and rivers in order to propose strategies to maximize ecosystem services at the same time that operating costs of the UWWS are minimized. Field experimental work will be conducted to understand the effects of UWWS discharges (organic matter, nutrients and priority pollutants) and river waste treatment capacity. A dynamic model of the whole UWWS and river will be developed and several management strategies will be tested against different types of environmental conditions and disturbances. These strategies include implementation of control and infrastructure upgrades. The knowledge acquired will be integrated into an Environmental Decision Support System that water managers can use to make decisions.
