Cadagua Signs Two New Contracts in Spain

Cadagua has signed a three-year contract for operations and maintenance of the iWWT (industrial Wastewater Treatment Plant) that the Heineken brewing company has at its facilities in Jaén.

The Valencian Community’s Department of Wastewater Treatment has also awarded them the contract for operations and maintenance services for Aspe‘s sanitation system and wastewater purification.

Maintenance at the Heineken treatment plant

Since the start of January 2019, Cadagua has provided all of the resources, including materials as well as personnel, needed for the operation and maintenance of Heineken’s iWWT to ensure smooth functioning under optimal conditions from the very start, committing to continually improving the process, optimizing it, improving maintenance for the facilities, and implementing a high-quality system, as well as working on elements related to preventing workplace hazards.

Heineken Spain has hired Cadagua to carry out numerous projects over the last few years at factories in Valencia and Madrid. Cadagua also provides operation and maintenance services for the purifier at the Heineken factory in Quart de Poblet (Valencia).

Cadagua has multiple references from projects in the agri-food sector from such well-known firms as Mahou-San Miguel, Heineken, Damm, Estrella Levante, Estrella Galicia, García Carrión, Cobega Coca Cola, Font Salem, Panibèrica, and Nufri, along with references like Saic, Smurfit, UIPSA, EUROPAC, Papelera Alquería, CELESA, and Kimberly Clark in the paper manufacturing sector.

The water purification and sanitation system at Aspe

The new contract awarded by the Department of Wastewater Treatment started on March 1, 2019, and it will be in effect for 4 years, with the possibility of annual extensions for a maximum of 4 more years.

Aspe’s WWTP has a treatment capacity of 2,500 m3/day and an average rate equivalent to 27,083 residents. It has a conventional biological treatment that uses prolonged aeration and a sludge treatment system that uses a gravity thickening process and dewatering through belt filters and centrifuges. Additionally, the WWTP at Aspe has a post-treatment system for sludge that uses a composting plant consisting of 4 drying tunnels with a 308 Tm ms/year/tunnel capacity.
