Located on the southwest edge of Jubail Industrial City, Eastern Province it has an approximate area of 500 ha and is about two metres above sea level. These are man-made, evaporation lagoons, using organic waste water supplied from Jubail Industrial City. The site was a key foraging and roosting site for waterbirds & shorebirds. The site is situated in a sabkha area that has been shaped by landfill, with
banks to divide up the area. The water supply comes from excess treated sewage waste and is only 0-30 cm on average, is very shallow and is thus very susceptible to movement by wind, with a resultant tidal effect whenever the wind changes direction. The majority of waste water is supplied to the site from October to May and so some of the wet areas dry up during the summer months, unless there has been some rainfall. Rainwater increases the volume of water, sometimes dramatically, and the surface can increase greatly, up to a maximum recorded of c.2,500 ha. In addition to these lagoons, three large (c.100 ha) concrete reservoirs are included in the site.The treated organic water results in the production of a huge biomass of microflora and of microfauna, which in turn provide the basis of the food chain for enormous flocks of feeding birds. The concrete reservoirs and some areas of the lagoon edges are fringed with Phragmites reeds and Tamarix scrub.
