Adwea is building self-powering sewage plant

Gas emanating from sewage treatment can be harnessed to power the process.

A ‘landmark’ sewage plant contracted by the Abu Dhabi Water and Electricity Authority (Adwea) is to ready by the end of 2010, the supplier of the generators for the project has said.

The plant will harness biogas stemming from the sewage process as feedstock to be used in gas generators, said Wassim Aboushaar, general manager at Cummins, who supply the power generation machinery.

The gas generators will be supplemented by diesel generators. The heat emanating from these generators will be used for the treatment process, Aboushaar added, and excess power will be fed into the Abu Dhabi power grid.

“ We are now doing the installation, the final commissioning and handover should be at the end of 2010,” said Abushaar.

The size of the contract for the generators, piping and the installation is between US$20-30 million, said the general manager.

“This is really a landmark and a unique project in the Middle East,” he added.

Abushaar also confirmed that Cummins had been awarded the contract for building a 10MW power plant at the Sheikh Khalifa Palace complex in the Emirate of Al Ain for $10 million on July 6.
