Abu Dhabi awards $161m sewer contract

Civil contractor Mabani Delma has landed an AED590m (US$160.6m) contract to build a 22km-long Deep Trunk Sewerage System for Abu Dhabi Sewerage Services Company.

Mabani Delma, which is part of Abu Dhabi-based Delma Emirates Group, won the tender after beating bids from 12 other companies.

The trunk system will run from Mafraq to Khalifa City B and will include Baniyas. It will involve laying 16km of deep non-destructive method (NDM) sewer lines at a depth up to 40m and 6km of open-cut sewer lines, as well as the construction of a new pumping station at a depth of 38m. This will replace 12 current pumping stations.

The project, which will link several residential and industrial areas, is set to be completed by 2015.

"For a project this ambitious, the government needed a partner with not just a successful track record for winning projects but one that has established its credentials for delivery and efficiency and overall dependability to complete the project to the most exacting global standards within the timeframe," Mabani Delma said.

According to its website, Delma Emirates Group has delivered more than US$8bn of infrastructure projects since its inception, in fields such as civil engineering, oil & gas, earthworks and water treatment networks.
