The Glencorse Water Project is all about providing a brand new state of the art water treatment works for Edinburgh. It’s going to supply about 450,000 people. A water treatment works requires that we take out the bacteria and the dirt from the water. A lot of effort is required to make that water suitable for drinking

Glencorse water treatment works is very innovative, one of the really clever things that we’ve done is to have a world first mobile pipe production plant, normally you would speak to the expert manufacturers over in Scandinavia but on this occasion we decided to bring the factory over to Edinburgh and set up a mobile pipe production unit on the pipeline route, so that actually saved us a million lorry miles which is a huge reduction and a huge carbon footprint saving for the project as well.

Of course, doing our bit for conservation is something we can all do. We encourage our customers to switch the taps off when they’re brushing their teeth or perhaps use a bucket instead of a hose when washing the car. For us, that means that we’re using less power, it means we’re using less chemicals and that all reduces our carbon footprint, so we’ve all got our part to play.

Engineers all over the world are thinking about innovative ways to create energy from sunlight from wind and from water. One of the really clever things we’ve done on the Glencorse project is to create energy from the power of water via this hydro-turbine and that will create about a third of the power needed to run our water treatment works. As civil engineers, we need to be able to produce good clean water 365 days a year whether it’s sunshine, or whether we’ve got 3 feet of snow. A supply of water is also essential to industry and by providing a new water treatment works here, we’re ensuring that industry in Edinburgh can continue to grow.

Can you believe there’s been almost 300 people involved in building this water treatment works? We’ve had everyone from tradesmen working with tools, architects, archaeologists. We’ve had designers, we’ve had civil engineers, mechanical engineers, and electrical engineers. There’s been a huge amount of people involved in this project.

There’s a massive amount of communication involved in this project, both written and verbal, we have to keep customers informed, we have to keep businesses informed about how we’re going to effect their lives and their businesses, so if we’re digging up a road for example, we need to make sure everyone knows and that’s through letters, that’s through our project website and that’s through having ‘meet the team’ days where members of the public actually come out to the construction site and meet the team that are delivering the project.

In the early stages we used computerated design packages and people actually worked remotely with these packages so they were contributing to the design from various parts of the world.

And within the works itself we have a fully automated 21st century system controlling the works.  We gather enough information to make sure that we can produce 175 million litres of water from this plant every day and to make sure that water is there for breakfast and tea time, we store it in a tank that’s one of the largest in Europe and it holds 90 million litres.

Another big challenge is taking a large works of this scale and fitting it sensitively in to the foothills of the Pentlands. The Pentland Hills are known for their beauty, their natural beauty, what we've done here is we've built the tanks below the ground and we’ve covered them with grass. We’ve also covered this water treatment works with the largest grass roof in the United Kingdom so that for generations to come, those tens of thousands that walk the Pentland Hills, they’ll never actually know that we are here - and we're proud of that.
