Construction works on hazardous waste landfill in 2008
COWI was in charge of the detailed design for remediation of an industrial site polluted with mercury. COWI's responsibility also covered the detailed design of a hazardous waste landfill for more than 4 million m3 of mercury contaminated waste, including bottom sediments of the Nura river.
Drinking water resource in danger Decades of industrial activities at a factory in Termitau city on the bank of a water reservoir and the Nura river resulted in accumulation of mercury containing waste and sediment which posed a risk for health of water users in areas downstream from Temirtau, including the Kazakhstan's capital Astana city. 

Detailed design for demolition

Based on extensive field investigations and assessments of historical industrial activities, a detailed design was proposed for demolition of the former industrial facilities and clean-up of the sites. The demolition and clean-up waste should be safely disposed at an enginered landfill designed according to the specific conditions of the selected site.

Risk elimination project under implementation After a series of public consultations, the set of design documentation was approved by the local, regional and national authorities and was tendered as works contract.
