It was the first community MBR wastewater treatment plant in Saudi Aramco. A successful story with many valuable lessons learned. Udhailiyah STP used to be a secondary packaged wastewater treatment plant which does not meet Saudi Arabia government and Saudi Aramco effluent requirements/standards for re-use in unrestricted irrigation. Plant effluent was disposed off into a huge evaporation ponds and never reused except for small quantities for in-plant irrigation. The plant is located in a remote area with little or no nearby residential development. Saudi Aramco environmental policies and government regulations necessitate expanding the plant and upgrading the treatment process to provide tertiary quality effluent meeting BOD, TSS, ammonia, nitrate allowable limits which makes it suitable for unrestricted irrigation. This paper will share with you the lessons learned from upgrading the existing package wastewater treatment plant to a Membrane Bioreactor (MBR) .This includes wastewater plant technology selection, designing, construction, commissioning and start-up of the plant. These lessons will improve the knowledge and understanding for achieving future successful jobs. The project started in July 2007 and was completed in November 2010. The biggest challenges during the expansion work were the construction phasing needed to minimize interference or interruption to the operation of the existing plant, working in remote desert climate and meeting the completion schedule. Who should attend Design and project engineers, professionals involved in operation and maintenance of wastewater treatment plant, ,construction contractor's key personals ,students and persons involve in wastewater plant technology selection, designing , construction , commissioning and startup
