Asia Pacific
Biwater have been active in Asia Pacific for over 45 years. In 1972, Biwater first secured a contract to deliver a state-of-the-art water park in Indonesia called ‘Jaya Water Ancol Park’. The water park was highly anticipated by local residents and helped to position Jakarta as a tourist destination before ‘Ancol Dreamland’ was developed.

Edwin Tan
Regional Director for Asia Pacific
Edwin joined Biwater in 2016 to oversee the Group’s regional development. Coming from a background of project management and plant operations with a Civil Engineering BSc (Hons.) Degree from the University of Leeds, Edwin has an in-depth knowledge of technical requirements for large-scale infrastructure and construction projects.
Edwin’s water industry career saw him start out as a Project Engineer in Malaysia. One of his first jobs involved the delivery of a 950 MLD water treatment plant in Sungai Selangor Phase II, Malaysia.
With a keen interest in project finance and project management, Edwin went on to manage the delivery of water design-build projects and operations contracts across Asia Pacific. For a period of eight years, Edwin relocated from Malaysia to Thailand to manage water projects country-wide for Veolia.
Most recently before joining Biwater, Edwin was Regional Director, Business Development, for Veolia and an Advisor for the Food and Agricultural Fund (Caudex) in Asia.

Our projects in Asia Pacific
The table below provides an overview of some of our recent projects in Asia Pacific, as well as a number of our flagship projects. *Based on Biwater’s financial accounts year ended 30 June 2017
Mui Wo
Hong Kong
New build
Turnkey design and construction of a membrane bioreactor (MBR) plant, which included odour control and sludge treatment provisions. The new works were connected to the existing wastewater treatment plant with the necessary pipelines, services and utilities. MBR was the chosen technology for the new works because of its ability to produce quality effluent meeting the most stringent water standards. Its modular configuration also helped to reduce the footprint of the works and provide a level of flexibility. Due to its modular design, further expansion is made easy if required in the future.
Scope of works:
Design and construction.
Wastewater treatment capacity:
7,400 m3/day
7.4 MLD
2 MGD US
Stonecutters Island
Hong Kong
Upgrade
Upgrade and expansion works to the main pumping station, sediment tanks and ancillary facilities. The new facility was built to handle wastewater treatment for over five million Hong Kong residents. As a result of these works, wastewater treatment capacity increased to 2.4 million m3/day. The plant featured the largest sewage pumping station at the time of commissioning and was awarded Wastewater Project of the Year (Distinction) in the 2016 Global Water Awards.
Scope of works:
Design and construction.
Wastewater treatment capacity:

Matara and Nilambe
Sri Lanka
New build
Two rural water schemes were built to increase drinking water supplies to remote communities, spanning hilly terrain and the flatter coastline. In Matara, river intakes were constructed further upstream to overcome issues with increased saline intrusion. Where possible, the sites were located at a high level to allow water distribution by gravity, which greatly reduced ongoing operational costs. As a part of the contract, a bridge crossing was built at Nilambe to provide a pedestrian river crossing, as previously river crossings could only be made by boat.
