World’s Largest Wastewater Treatment Plant Powered by GE

As part of the new contract with GE and the world’s largest wastewater treatment plant, eight vertical variable-speed power conversion drive trains will power the STEP Feed Pipeline Project, GE solutions will increase energy efficiency, lower maintenance, and control plant water flow, and will help strengthen the presence of GE’s power conversion business in the Middle East Water Industry.

GE’s Power Conversion business announced that it has won a contact of more than $10 million to supply eight pump drive trains, as well as process automation for the largest wastewater treatment plant in the world. It will be located just outside of Abu Dhabi, United Arab Emirates, and will provide water for local agricultural needs.

This pumping station project is part of the Strategic Tunnel Enhancement Program (STEP), a 40-kilometer long wastewater tunnel intended to address rapidly growing needs for the collection and transport of used water generated by the growth of Abu Dhabi. It is a key element of the government initiative to provide local agriculture with improved access to good quality water.

When fully operational in 2030, the plant, featuring wastewater pumps will be able to treat up to 70,000 cubic meters of wastewater every hour. The pumps will be driven by GE’s vertical variable-speed motors, a highly specialized application for vertical motors working at low speed (500 revolutions per minute at rated speed).

GE also provided a preliminary harmonic study to help the customer on the overall plant grid study. Its integrated automation solution has been designed to enhance the control of the pump and the motor.

“The company is very well positioned both from a technical and commercial point of view,” said Hitachi Plant Technologies, Ltd. “GE’s Power Conversion business provided deep domain expertise and technical support to Hitachi and the EPC contractor from the start of discussions right through to the signing of the contract. GE showed its flexibility as a global leader in rotating machines by producing motor designs not available as standard in the marketplace.”
