The biggest investment in the Greater Glasgow area's waste water network in more than a century is to be announced today.

The publicly owned company Scottish Water will start a multi-million pound scheme of work over five years, including upgrades to around 200 combined sewer overflows, improvements in Glasgow south west, and anti-flood schemes.

The programme, which will support around 500 jobs and 50 apprenticeships, will be launched at Glasgow's Science Centre by Deputy First Minister Nicola Sturgeon.

Geoff Aitkenhead, Scottish Water's Asset Management Director, said it would make Glasgow's waste water infrastructure fit for the 21st century.
