The Consejería de Fomento, Vivienda, Ordenación del Territorio y Medio Ambiente of the Autonomous Community of Cantabria awarded the construction work to renew the sewerage system in the catchment area of the Arroyo Pozeirún in the municipality of Escalante on 7 September 2026. The contract covers 180.391 Euro and provides for the construction of a new Colector Pozeirún and associated secondary pipes. The new collector will be connected to the colector general de las Marismas de Santoña .
According to the regional government’s statement, the project is intended to end direct discharges of untreated wastewater into the natural watercourse of Arroyo Pozeirún. It includes removing the old channel laid in the stream bed, installing a main collector around 227 metres long, and building connection pipes and protective measures along affected road sections. This is intended to reduce pollution in the transitional waters of the Marismas de Santoña and improve their ecological status.
The project stems from a standard procurement procedure documented in the official registers. The proposal had previously been made available for environmental consultation; in the records it is listed under the title Expediente 121/24 AC The ministry cites technical and environmental protection requirements, including provisions on occupational safety, noise reduction and the restoration of road surfaces once the work is complete.
The authority did not provide a detailed construction timetable in its contract award notice. This will be set out in the implementation plan drawn up by the contractor. For residents, the sequence of connection work and any temporary closures or diversions are important. According to the ministry, these will be coordinated to minimise disruption and maintain utility services.
The renewal in Escalante is part of a wider regional administration investment priority in wastewater infrastructure. The aim is to strengthen urban drainage and water protection in coastal and wetland areas such as the Marismas de Santoña over the long term. According to the authorities, the connection to the main collector will help ensure that wastewater is treated and prevent future operational disruptions.
The award marks the formal launch of the project. Further details on implementation, construction supervision and the assessment of the measures’ effectiveness in the transitional waters are expected to be announced when work begins. The regional government emphasises that protecting the Marismas de Santoña as a Natura 2000 site and ensuring basic sanitation for the population of Escalante are guiding priorities for this investment.
