1. General information
2. Objectives of the intervention
Goals of the intervention
"A cohesive approach combines rationalisation of sewage plants with richer fauna in the biggest natural river in Aarhus."
"The project will be a bonus for the environment, through rationalisation bringing major savings in running costs, because the increase in minimum water flow will improve the water quality in the river, creating better conditions for more fish to the benefit of anglers and the balance of nature. The river will also be ensured water volume and quality which will fulfil local environmental objectives and the expected high environmental objective for Giber River in the national water plan." (Ref. 1)

Quantitative targets
The minimum amount of water in Giber River should be increased from the current 45 litres per second, to over 100 litres. (Ref. 1)
Monitoring indicators defined
minimum amount of water in the Giber River in liters per second (Ref 1)
Sustainability challenge(s) addressed
Habitats and biodiversity conservation: What types of conservation goals are / were defined for the NBS intervention?
Habitats and biodiversity conservation: What activities are implemented to realize the conservation goals and targets?
Implementation activities
The increase in water flow in Giber River will be achieved by a range of different measures, such as pumping purified waste water into the river and building a string of rainwater collection ponds which will be allowed to slowly drain into the river. (Ref. 1) A measuring station at the top of the river measures when flow drops below 100 litres per second. If it does, water will be added from natural groundwater tributaries, stored rainwater and purified waste water from the return pump. (Ref. 4)
