UAE’s largest sewage plant built by L&T inaugurated

DUBAI, April 24, 2019

The UAE’s largest sewage treatment plant built by Larsen & Toubro for the Dubai Municipality was inaugurated recently.
 
The 375,000-cu-m-per-day sewage treatment plant (STP) at Jebel Ali (Phase 2) was inaugurated  by Engineer Dawood Abdulrahman Al Hajiri, director general of Dubai Municipality in the presence of Talib Julfar, assistant director general, Fahd Al Awadhi, director and other senior officials of the Dubai Municipality. 
 
Built along with JV partners, Besix, the Jebel Ali STP is the biggest such plant constructed by L&T Construction, completed and delivered ahead of schedule maintaining the highest standards of quality and safety. 
 
“This is perhaps the first project of this magnitude and complexity that has been completed and delivered ahead of time with not a single minute lost due to incidents of any kind,” said S N Subrahmanyan, chief executive officer and managing director, Larsen & Toubro. 
 
“With water becoming such a precious commodity the world over, projects like these make a huge difference to the ecology and it is always good to be associated with such projects,” he added. 
 
The Jebel Ali Sewage Treatment Plant Phase-2 Expansion is Dubai Municipality’s strategic project of 375,000 cu m per day to meet current and future demand generated from the surrounding area that will see major new developments including Expo 2020. The Jebel Ali treatment facilities have total treatment capacity of 675 MLD which includes existing 300 MLD of Phase 1. 
 
“The Jebel Ali STP is critical to the water conservation plans of our client, Dubai Municipality, for it allows the city to reduce the use of expensive fresh water by reusing 375,000 litres per day treated sewage effluent for non-potable applications such as irrigation,” informed S Rajavel, senior vice president and head, water, smart world and communication, L&T Construction. “That we have been able to achieve the very high standards demanded by the client and clock 10 million safe man hours in the process reinforce our credentials as the foremost Indian construction company in the Middle East.” 
 
The STP, built on a build, test, commission, operate and maintain mode, features primary, secondary and tertiary treatment process units such as screening, grit separation and removal, primary sedimentation (flight and scrapper mechanism), biological reactors, final settlement (bridge and scrapper mechanism), tertiary filtration (gravity filters), ultraviolet (UV) disinfection and chlorination.
 
The sludge treatment process includes sludge thickening (rotary drums and belt thickeners), anaerobic digestion, dewatering (centrifuge), sludge drying (thermal paddle dryers) facilities and robotic bagging system. 
 
Other scope of works included odor control facilities, Phase 1 STP interconnection, upgrading works in Phase 1, effluent pump stations, effluent reservoirs and biological reactors.  - TradeArabia News Service
