EDAR Caldes de Montbui

EDAR Caldes de Montbui is a wastewater treatment plant located on the outskirts of the town. Our intervention consisted of refurbishing the roof of one of the facility’s buildings, including the installation of a photovoltaic system.

Commissioned by the Besòs Tordera Consortium, we carried out the comprehensive refurbishment of the roof of the dehydration and reagents building at the Caldes de Montbui WWTP. The project improved the watertightness, safety and energy efficiency of the facility through the application of advanced technical solutions and rigorous site management, resulting in an efficient, safe and sustainable intervention serving the water cycle.

WE HAVE BROUGHT TO FRUITION

Improve building conditions and safety

The intervention improved the building’s watertightness, durability and energy efficiency by replacing the existing roof with a new system of girders, reinforced concrete beams and thermally insulated metal sandwich panels with anti-corrosion finishes. The works also ensured a safer and more efficient working environment for the WWTP’s technical staff.

WE HAVE MADE POSSIBLE

A commitment to sustainability

Installation of self-consumption photovoltaic solar panels with a capacity of 54.6 kWp (50.0 kW nominal).
Use of recyclable and long-lasting materials, reducing waste generation and future energy consumption.
Removal of the old metal roof elements, sent to authorised recycling plants, achieving material recovery of over 80%.
Improved thermal insulation of the building, reducing energy demand.

WE HAVE WORKED TO THE HIGHEST STANDARDS

To incorporate innovative solutions

The project incorporated state-of-the-art construction solutions for industrial metal roofs, with high thermal-efficiency sandwich panels and mechanised fixing systems that allowed installation without interrupting internal operations. Digital site monitoring (as-built BIM model) was used to coordinate interfaces and ensure traceability of the works, improving safety and execution planning.
