Saadiyat Island is roughly triangular in shape and covers an area of approximately 27 square kilometres. It is located east of Abu Dhabi Island in the Emirate of Abu Dhabi. The Tourism Development and Investment Company (TDIC), as the master developer, envisaged a mix development of Saadiyat Island divided into seven districts, namely: Cultural, Marina, Beach, Promenade, Lagoons, Reserve and Retreat Districts.

The development of Saadiyat Island is continuing with a large number of facilities completed, some under construction and many others planned to commence soon. As part of the development of the island the sewer infrastructure is a critical component with the first phase of this, comprising of Sewage Treatment Plant 1, Sewage Pumping Station 1 and the associated network, being in service since December 2010. As permanent developments were completed, Sewage Treatment Plant 2 will be commissioned to treat an average flow of 78,000 m3/day.
