Contact Us





We have over four decades of experience in designing, procuring, manufacturing and constructing various types of membrane systems using microfiltration, ultrafiltration, nanofiltration and reverse osmosis to treat seawater, brackish water and municipal wastewater.

Biwater currently has the largest installed capacity of membranes in the United States as well as the largest installed capacity of membrane bio-reactors (MBRs) in the UK. In 2003, we built one of the largest nanofiltration plants in the world (150,000 m3/day) and have installed over 1.4 million m3/day capacity in membrane treatment since 2000.  In 2009, Biwater completed the 228,000 m3/day reverse osmosis plant at the Sembcorp Changi NEWater Plant in Singapore, the largest in South East Asia.

We built our first reverse osmosis plant back in 1971 which at the time represented 10% of the world’s reverse osmosis capacity, however, since these early plants, due to both the fall in operational costs and Biwater’s increased knowledge and expertise, membrane technology has seen rapid progress and cost reduction. These changes have seen many countries around the world embrace this technology.

Biwater is unique as we combine our experience in a wide range of membrane applications with a vast knowledge of water and wastewater treatment and are able to propose the plant to best meet our clients’ requirements, by selecting either a membrane plant or a ‘conventional’ system.
