The drinking water treatment plants (ETAP) located in Sant Feliu de Llobregat are being remodeled to adapt to the new European directive. According to sources from Aigües de Barcelona, ??responsible for the work, the two Estrelles DWTPs – the name of the facilities – are being adapted, which have a treatment capacity of up to “1,000 liters per second.”
These facilities are fed by the aquifer wells in the lower valley of the Llobregat delta and “currently only receive chlorination treatment.” But Royal Decree 3/2023, which transposes the European directive 2020/2184, on the quality of drinking water “limits the presence of new contaminants.”
So to adapt to the new regulations, a new reverse osmosis line and a new active carbon line are being built. In this way, according to these same Aigües de Barcelona sources, 75% of the water can be treated with active carbon and 25% with reverse osmosis, “guaranteeing a necessary resource in the current context of drought.”
The works, which are advanced and in fact are very visible from the paths of the Llobregat River that cause a sensation among athletes, “will end in April 2025 and will ensure the quality of the water treated in this water treatment plant, which currently has one of the two ETAPs in operation.”
