In many areas around the world, also here in The Netherlands, the supply-demand profile of fresh, clean water is changing. Lasting drought periods reduce the availability of groundwater and surface water during the warm seasons while the demand for clean and fresh water often increases in those periods. On top of this, in other areas around the world, the lack of proper sanitation infrastructure leads to severe pollution of fresh water sources.
“We must urgently scale up investments in healthy watersheds and water infrastructure, with dramatic improvements in the efficiency of water use”, said UN Secretary-General Mr. Guterres during the last World Water Day, adding that the world must anticipate and respond to climate risks at every level of water management. Moreover, wastewater should be recognised as a valuable resource.
