2012-02-27 - ABB is providing electrical balance of plant service for the Changi Water Reclamation Plant, the world's largest covered wastewater treatment plant and one of the most visionary and innovative water projects on the planet.
The Changi Water Reclamation Plant (CWRP) is one of the largest water reclamation facilities in the world. Along with the Deep Tunnel Sewerage System, the CWRP will collect, treat and purify every drop of wastewater produced by Singapore over the next 100 years, replacing all existing local plants in Singapore.
Located at the eastern edge of Singapore, the plant is mainly underground and is built in a stacked arrangement, thus occupying a land area less than one-third of a conventional layout.
The plant produces cleaned wastewater to the highest international standards, suitable for deep sea discharge in the Straits of Singapore. On the rooftop, CWRP incorporates an operational facility capable of reclaiming potable water that is fit for human consumption or for high-requirement industrial use.
CWRP was crowned the Water Project of the Year at the prestigious Global Water Awards 2009 in Switzerland.
"ABB engineers have been very responsive, accommodating and helpful to our maintenance team. For that, we are very grateful and appreciate their efforts and diligence in keeping our critical equipment in good working order."
Powering Singapore's water superhighway
Amounting to a project cost of US$3 billion, the CWRP uses the most advanced technology available to treat twothirds of the 1.3 million cubic meters of wastewater Singapore generates daily.
The plant is being extended to a daily maximum capacity of 2,400,000 cubic meters - sufficient to accommodate the entire needs of Singapore.
Building the CWRP threw up many technological challenges and ABB played a prominent role in its construction by providing advanced power and automation expertise and products, such as high-efficiency motors and medium-voltage drives that enable critical parts of the process to operate at the highest levels of energy efficiency and reliability. In fact, throughout the entire Changi water treatment process ABB products and systems power, monitor, measure and speed-control crucial process equipment in the liquid and solids treatment modules, sludge drying systems, centrifuges and turbine generators, and effluent pumping station.
Water service for CWRP
After the Changi Water Reclamation Plant went into full operation in June 2009, ABB was following up with the customer when it was noticed that CWRP had a demand for a complete service package. The customer had been contacting various ABB departments regarding service requirements, so ABB coordinated a response across several of its divisions and created a single comprehensive service contract offering.
With its wide range of products, systems and services, ABB follows the whole life cycle of Changi Water Reclamation Plant, from engineering to construction, and now, service and maintenance. ABB supports CWRP in identifying the best solutions for their specific needs, including maintenance and asset optimization.
The service contract from the Public Utilities Board, valued at just under US$2 million, is a three-year service and maintenance agreement for the electrical balance of plant (EBoP), which will help ensure reliable and efficient operations at CWRP. The service package includes the maintenance of critical ABB equipment such as high-efficiency, medium voltage motors and water-cooled, medium-voltage drives that power and control the huge pumps at exceptional levels of energy efficiency.
Also covered are high-voltage distribution boards and transformers; mediumvoltage switchgear; low-and mediumvoltage transformers; and low-voltage switchboards, switchgear, motors and drives.
Under the service contract, ABB provides, 24/7, certified standby engineers and response to site within four hours for critical equipment. A key engineer is assigned to support the customer and internally coordinate various service groups to establish a single point of contact.
Through this contact, ABB helps CWRP to plan and execute regular maintenance. Other value-added aspects of this comprehensive service contract include access to ABB's Web-based Parts OnLine spare part information and ordering system, maintaining the failure
log book and supplying basic training and refresher courses for ABB equipment operation.
With ABB’s Logistics Center Asia (LCA) located in Singapore, local fast response on spare parts is available, thus allowing CWRP to minimize their spare parts inventory.
Last but not least, and viewed by the customer as very important, are the local Drive Service Workshops and Motor Service Workshops led by ABB factory certified personnel.
Key success factors in service
Despite the wide range of ABB equipment involved in the service contract, the customer perceives just one ABB entity.
This exceptionally easy interface makes it simple for CWRP to run and maintain its equipment. The CWRP maintenance team has peace of mind as ABB personnel will always be there to support and resolve any issues concerning critical ABB equipment. For full clarity, the customer has easy access to ABB's sales and service engineers via a clear and simple contact chart.
Changi Water Reclamation Plant has recognized how ABB's service can help increase the reliability and efficiency of their operations.
"We thank ABB for the service provided so far, and also for assigning proficient and efficient engineers to support CWRP. ABB engineers have been very responsive, accommodating and helpful to our maintenance team. For that, we are very grateful and appreciate their efforts and diligence in keeping our critical equipment in good working order," said Mr. Lim Swee Sen of Public Utilities Board.
