SUSTAINABLE WATER SUPPLIES

• A sustainable water supply requires individuals to use as little water as possible. It involves collecting and recycling water rather than relying on only freshwater from reservoirs.
• Home roof gardens are essential for rainwater harvesting and wastewater recycling.
• Groundwater also needs to be protected from pollution.
• Greenspaces filter pollutants as water pass through. The wastewater system in Freiburg allows rainwater to be retained, reused or seep back into the ground.
• Financial incentives are offered to local people for using water sparingly. In the Vauban district, water conservation includes: collecting rainwater for use within homes green roofs pervious pavements to allow water to soak through unpaved tramways to allow infiltration drainage wetlands Excess water from the River Dreisam is stored, which can be used in the city.
