Water reserves and animal sanctuaries are extremely rare in Qatar. As part of the Al Karaana lagoon rehabilitation project, Egis and its client do their best to maintain Al Karaana as a nature reserve and apply sustainable solutions to avoid further loss of amenity. The Project includes four major stages: design, cleaning and removal of all sources of pollution, rehabilitation of the lagoon to "no-development" land status and protection of the existing habitats.

Al Karaana Lagoon was constructed in 2007 and is approximately 4 km2 in size. It contains several old lagoons. Due to their location adjacent to the water treatment plant, around 200,000 m3 of treated wastewater were poured into lagoons on daily basis. Additionally, 100,000 m3 of domestic and industrial untreated wastewater were received on site via sewage trucks. Over the years, this has caused soil contamination, odor nuisances and environmental pollution.
The Client, Qatar Public Works Authority – Ashghal, together with the Ministry of Municipalities and were looking into several solutions, including covering the lagoons and closing the area. The ecological survey showed however that the lagoon area was still remarkably very much alive:
The findings led to the decision that the lagoons would be reclaimed and rehabilitated, creating an important animal settlement for the summer periods when fresh water is at scarce.
When Egis secured the Pre and Post Contract Professional Consultancy Services for the Reclamation of Al Karaana lagoons, the proposed solutions were to minimize the pollution and preserve the settled wild life for a long term:
The animals are already coming back to Al Karaana lagoons, occupying the restored ponds. First baby bird was born in the lagoon, truly marking the ecological win. The area turns green with planted trees and seeds.
The rehabilitation of Al Karaana lagoons has been a great success, although the works are still ongoing on site. The project has been widely recognized as an environmental accomplishment and in line with Qatar’s aim for the sustainability and fight with the climate change.
