Stanley Wastewater Treatment Works Upgrade
Project Overview
Scottish Water is investing £8 million to upgrade the Wastewater Treatment Works (WWTW) serving the village of Stanley in Perthshire.
The project will help ensure the site can continue to meet the community’s needs for many years to come, and help to protect the environment.
The overall programme of work is expected to be completed in spring 2028.
The work will be delivered by ESD, on behalf of Scottish Water.

What We Are Doing
The work will expand and upgrade the existing treatment works. It includes building new tanks, pumps and pipework to help treat wastewater more effectively and improve the overall performance of the site.
More specifically, this includes a new pumping station, a new Submerged Aeration Filter (SAF) package to treat 50 percent of the future flow, 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.

Latest Update: 26 August 2026
We previously advised of a start date of early August, however; this has since changed due to unforeseen circumstances.
Preparatory work will begin on site next week instead, with the installation of fencing and the temporary site compound. Tree felling will then begin on Monday, 14 September. The overall project is expected to last approximately 21 months, completing in spring 2028.
