Rehabilitation of a post-treatment water holding pond

project outline

The Neves Corvo mine is a copper and zinc mine operated by the Portuguese company Somincor, a division of Lundin Group.

The site’s existing holding pond, intended to contain wastewater following the completed treatment process, was non-functional due to a number of major problems related to its impermeability system.

Groupe Alphard’s mandate comprise the design of a new impermeability system for the 50,000 m3 capacity holding pond and the design of new hydraulic systems.
