Macquarie Infrastructure and Real Assets (MIRS) has sold off its final stake in Britain’s biggest water supplier Thames Water.

It follows the 11 years of the Australian bank’s investment, with the 26.3% interest now to be owned by Canadian pension fund Omers and Kuwait Investment Authority.

The companies snapped up the stake in Kemble Water, the holding company behind Thames Water, through its infrastructure investment arms Borealis and Wren House.

Macquarie suggests investing in Thames Water’s operations has led to a “significant reduction” in the level of leakage, with the network losing 25% less water than it did in 2006 and a substantial expansion to the waste treatment capacity of the network, including major improvements at the five large sewage works serving London.

It adds there has also been extensive green investment, including increased generation of renewable energy from waste and the creation of one of the largest floating solar panel schemes in the world.

Thames Water supplies drinking water to around nine million customers and treats 4.4 billion litres of wastewater every day.

Last year the company announced plans to exit the business retail water market.
