The Alcantarilla del Arroyal is a hydraulic infrastructure of the Campos Branch of the Canal de Castilla located in the municipality of Capillas (Palencia), at kilometer 129.600. Its importance lies in the essential function it performs within the canal system: allowing the passage and evacuation of water under the hydraulic route, guaranteeing the stability of the channel and the correct adaptation of the canal to the territory.
Unlike other canal structures built of stone, this culvert is constructed from cast iron pipes, a material that reflects the incorporation of industrial solutions into the hydraulic system. This type of conduit, buried and with limited visibility, is designed with a primarily functional approach, intended to efficiently manage water crossings without altering the canal’s profile or the immediate surroundings. Although specific data regarding its arch type or dimensions are unavailable, its construction demonstrates practical and durable engineering, consistent with the maintenance and safety requirements of the entire system.
For visitors, the Arroyal Culvert offers a complementary perspective on the canal, inviting them to discover the silent and often overlooked structures that made its daily operation possible. Integrated into the open landscape of Tierra de Campos, it allows one to appreciate how engineering adapted with simplicity and efficiency to the rural environment.
