ABB motors protect Singapore from flooding

ABB Automation Technologies : 02 March, 2007  (Company News)
The Singapore government is constructing a 350-meter tidal barrier to create a giant freshwater reservoir in the heart of downtown Singapore. Powerful, energy-efficient ABB motors will help keep the water level stable and protect the city from flooding.
When completed the giant Marina Barrage tidal barrier will span the 350-meter wide Marina Channel and separate downtown Singapore from the open sea of the Singapore Strait.

The barrage will function as both a dam and tidal barrier. It will create a giant freshwater reservoir that will supply one-sixth of the city-stateís needs for drinking water while protecting low-lying districts from high tides and monsoon flooding. As a bonus it will provide Singaporeans with a recreational marina and water sports resource of international standard.

The reservoir will help meet Singapore's growing demand for water. Today, Singapore consumes about 300 million gallons of water per day, equivalent to about 500 Olympic-sized swimming pools. By 2011, consumption is expected to increase by about one-third. About 50 percent of Singapore's potable water is now imported from Malaysia.

Pumping out excess water
When the reservoir water level rises during the monsoon rains, seven high-capacity pumps driven by seven powerful, energy-efficient ABB motors will keep the water level stable and prevent it from spilling over into nearby areas that are prone to flooding.

The barrage will act as both a dam and a tidal barrier, creating a giant freshwater drinking water reservoir while protecting low-lying districts from high tides and monsoon flooding.

The 1600 kilowatt, 6.6 kilovolt medium voltage motors were selected by Singaporeís national water agency, PUB, for their unparalleled energy efficiency and ability to operate at a low starting current. Three ABB alternators supplement the power supply when more than two pumps are in operation and provide standby power during blackouts.

PUB has previous experience of these long-life energy-efficient ABB motors, having installed 18 of them to pump influent and effluent at the Changi Water Reclamation Plant.

The Changi plant is one of the biggest wastewater projects in the world, with a treatment capacity of 800,000 cubic meters of wastewater a day that is expandable to 2.4 million cubic meters. In addition to delivering 18 motors and 18 ACS1000 drives, ABB supplied instrumentation, control and electrical distribution systems for various parts of the plant.
