The Puigcerdà Municipal Brigade, supported by an external company, carried out cleaning and review work over three weeks along the nine kilometers of the Puigcerdà Canal. This annual operation, performed every spring, extends from the water intake at Riutès, in La Tor de Querol, to the lake in Parc Schierbeck.

The International Canal is crucial for the hydrological balance of the Cerdanya capital, as it feeds both the lake, a prominent tourist attraction, and part of the water circuit used for irrigation and urban services, especially during periods of high demand. The tasks included removing vegetation and sediment, cleaning the canal, reviewing irrigation diversion points, and clearing the parallel path to facilitate monitoring.

This infrastructure has medieval origins, with the Puigcerdà Canal documented as early as 1310. With a route of approximately 14 kilometers, the canal draws water from the Querol River between Quers and Riutès, in La Tor de Querol, and crosses territories such as Enveig before reaching Puigcerdà via Rigolisa. Its shared management across the border has given it its international character.

Once in the town, the water flows into Puigcerdà Lake, from where it is distributed to orchards or used for urban services like cleaning. The council emphasized the importance of this periodic maintenance to ensure the continuity of the service and the good condition of the shared hydraulic system, thanking the collaboration of the Fundació Tallers de Cerdanya and the Consell Comarcal Brigade.
