Within the context of Monaco’s sea urbanisation project, our client is building a marine infrastructure that will constitute the first phase of a 6 hectare extension of the town into the sea. Comprised of protective barrier of 18 concrete chambers, the infrastructure will serve as the foundations for a new eco-district. Nomado supplied and installed a concrete laitance treatment unit in order for treated water to be discharged into the sea.

At this site, a huge amount of concrete is used and when concrete mixer trucks, skips and pumps are cleaned, effluent is generated known as concrete laitance. This effluent is loaded with aggregates, sand, concrete and fine particles. It is therefore necessary to treat this before being discharged in the natural receiving body, in this case the sea.
