Banks of the Tay
Stanley Waste Water Treatment Works is located on the banks of the River Tay close to the historic visitor attraction of Stanley Mills
What We Are Doing
The scope of the project includes a new pumping station, a new Submerged Aeration Filter (SAF) package to treat 50% of the future flow and loads and a new sludge storage tank.
A new humus tank, which is designed to remove fine solids from the effluent after it has passed through the new SAF biological filter will also be installed.
Environmental advisors have been involved in developing the project from an early stage and will be consulted throughout.
A planning application will be submitted to Perth & Kinross Council and if approved any conditions will be included within the design and construction of the project.

Why We Are Doing It
