At Enviro Networking and FuturENVIRO, we continue to be fully committed to the water sector, organising high added value Technical Conferences that showcase innovation for the enhancement of drinking water treatment, regulation and supply. On October 16th last in Barcelona, we held a one-day conference entitled ” Drinking water treatment, regulation and supply”, which provided information on the current situation of drinking water supply in Spain.
Water resource management in Catalonia
Jordi Molist, Director of the Water Supply Division of the Catalan Water Agency (ACA), began his presentation by describing the management of a scarce resource, recalling historic droughts and explaining that 70% of the region depends on groundwater for supply in different proportions, with groundwater resources meeting up to 35% of total demand.
In the final part of his presentation, he highlighted the guarantee provided by the Ter-Llobregat system, which, depending on the reserves in reservoirs, makes complementary resources available from the Del Prat seawater desalination plant, which has a capacity of 20 hm3/annum and the Tordera desalination plant, which has a capacity of 20 hm3/annum. Added to this are resources from wastewater reuse and increased groundwater extraction (drought wells).
Jordi also highlighted the injection of reclaimed water into the Barcelona aquifer (15,000 m3/day) and the reuse for industrial purposes of 19,000 m3/day to supply the Tarragona petrochemical complex, which in return renounces the use of an equivalent flow of drinking water.
General aspects of the supply sector
Fernando Morcillo, president of the Spanish Water Supply and Sanitation Association (AEAS), began his presentation by underlining the current challenges facing the sector, such as lack of investment, particularly in renovation. He also highlighted the importance of cost recovery, harmonisation, transparency and citizen responsibility, along with emerging contaminants and micro-contaminants. During his presentation, he provided an overview of the situation in Spain, where 64% of urban water is consumed in domestic use, 15% in industry and commerce, and the remaining 21% in other areas, such as municipal and institutional uses.
