Darnius City Council, With The Intention Of Complying With Royal Decree 3/2023, And At The Same Time Ensuring Or Guaranteeing The Supply Of Drinking Water To The Population, In 2022 Carried Out Works That Consisted Of Bringing The Water From The Darnius-Boadella Reservoir To The Municipal Tank. Once There, The Potabilization Treatment Consisted Of: • Physical Decantation Treatment Prior To Entering Utap. • Compact Water Treatment Unit Consisting Of: O Two Filters With Multilayer Beds (Silica + Granite + Anthracite) Odifferential Chemical Treatment With Chemical Dosing Of Sodium Hypochlorite (Oxidation), Coagulant (2 Points) And Flocculant In The Second Stage, Necessary For The Removal Of Turbidity, Reduction Of Organic Matter. Once The Works Were Finished And Electricity Supply Was Available (End Of 2025), The City Council Has Requested Authorization From The Catalan And Water Agency To Use The Water From The Dam Foot, Once Treated. This Authorization Has Been Denied, Given That There Has Been A One-Off Episode Of Excess Organic Matter In The Water At The Foot Of The Dam And That Our Compact Treatment Plant Is Not Capable Of Removing.
