Weekly. To combat drought, one of the solutions is the reuse of wastewater, but in Portugal only 1% was treated this way.
Portugal Portugal is not a new problem, but the lack of rain that this winter puts almost all of the country in meteorological drought at the end of January) raises a series of questions: does the storage of the reservoirs; obliges to control the water that is taken from them to produce electricity or irrigate agricultural land; that we are slow to take paper away as solutions to a lack of resources that will become more recurrent, due to climate change and its efficient management.
In the last 20 years, water availability has dropped by 20%. And, by the end of the century, it is predicted that it will rain 15% to 20% in the North of the country and 25% to 35% in the South and that they will be droughts that model every 10 years to occur at three times a decade, according to models physicists by the team of the studied atmosphere physicist Pedro Matos Soares, from the Faculty of Sciences of Lisbon.
From the measures announced in the wake of the 2017 drought, it takes time to put in place, such as many rehabilitation of dams to increase their capacity and quality of investments, such reductions for network reductions or the use of treated wastewater from 50 stations of treatment.
