International Division
During DNC’s construction of a full-scale sewage facility in Papua New Guinea’s heavily populated capital (Port Moresby), coral from the local coastal reef was transplanted to another site to protect the rich marine environment from treated sewage to be piped into the sea (Port Moresby Sewerage System Upgrading Project/Papua New Guinea).
