Mott McDonald wins pumping station contract

100m deep underground station will be one of the world’s largest pumping stations

Abu Dhabi Sewerage Services Company (ADSSC) has appointed Mott MacDonald to engineer contract administration and site overview for its development of one of the world’s largest underground pumping stations, in the Emirate of Abu Dhabi.

At 100m deep and with a 40m diameter, the station will have a peak capacity of 3.3million cubic metres per day

The station is part of expansion plans designed to address projected growth rates in the Emirate and will sit at the end of the Strategic Tunnel Enhancement Programme (STEP), a 41km tunnel sewer and system. The facility will also house electrical and power generation facilities, operations and maintenance facilities, standby power fuel storage and pumping and a flow distribution facility.

“The UAE is the third largest consumer of water in the world after Canada and the USA,” said Mott MacDonald project director, Peter Hall.

“There is a daily water consumption rate of nearly 550 litres per person in a region that receives less than 1cm of rain per year. Therefore, management and reuse of wastewater is a critical component to Abu Dhabi’s long-term sustainability,” Hall added.

Mott MacDonald’s role is to involve project, design, cost, contract and health, safety and environment management, with the project due for completion mid 2015.
