ONDOAN Group companies

ONDOAN was founded in March 1982 with the objective of developing Engineering Services. The initial Company Object was defined as being the design, construction and supply of turnkey Auxiliary Installations for Industry and Public Administration. ONDOAN initially specialised in Water Treatment and Purification. In 1984, experts in other areas joined the company and it embarked on the design and construction of General Installations for both Industry and Special Buildings. In the following year, 1985, the company took its first steps in Research and Development Projects in the Industrial Wastewater field, and this activity was at the origin of its Environment and Prevention Unit, created in 1991. 1993 was another very important year in Ondoan's history, as this was when the company transferred its facilities to its current base at the Zamudio Technology Park. The subsidiary company Ondoan Servicios, S. A., specialising mainly in Maintenance, was created in the same year. In 1998, ONDOAN opened its Aretxabaleta office. In 2001, ONDOAN Auditoría y Control, S.L. was created, a company specialising in inspection, control and official and regulatory audits in the fields of Occupational Risk Prevention and the Environment. In the same year, the Donostia/San Sebastían office was also opened. In 2004, ONDOAN opened its Vitoria-Gazteiz office at the Miñano Technology Park. In 2007, the company KELAN joined the ONDOAN Group. This incorporation reinforced the line established by ONDOAN over these years: to foster the activities of Technical Consulting, Engineering Studies and Projects and Technical Assistance and Maintenance, with the aim of completing its range of services, and this has enabled the company to cater better for the demands and needs of our customers.
