Tay Street and Shore Road's Super Sewer

Tay Street and Shore Road Sewer Upgrade

A significant project totalling £23 million investment is nearing completion at Tay Street and Shore Road, which involves the installation of an upgraded sewer pipeline with a diameter of 2.2 metres. This approx 500-metre section of ‘super sewer’ will play a key role in supporting the city’s continuing growth, while also reducing the risk of sewer flooding affecting low-lying areas near the Tay between Muirton and the city centre.

This work is being delivered on Scottish Water’s behalf by its capital project delivery partner Caledonia Water Alliance. Click the video below to find out more information on this project.

By super-sizing a 500 metre section of the trunk sewer next to the River Tay, we can provide additional capacity for new development while also alleviating sewer flood risk that affects our customers. Photo credit: Paul Milligan.

Latest Update May 2025

We've been on site on Tay Street and Shore Road for two years, with sections of the road closed to vehicles since May 2023, and traffic management in place to safeguard pedestrians, cyclists and site workers.

The ‘over-pumping’ set-up – overground pipes which transported waste water flows while the new sewer was being connected – has been removed, and the focus will shortly turn to reinstating the road before it can re-open fully to traffic once more. Perth and Kinross Council will take on the site from next month, with the road anticipated to re-open fully by the end of June. Traffic management will remain in place until this time.

Tay Street Latest Update

The majority of the sewer upgrade on Tay Street has been completed alongside a full kerb to kerb road reinstatement carried out by Perth and Kinross Council.

Tay Street Traffic Management

Tay Street is partially open, acting as a cul-de-sac. Entry and Exit is from the junction of Canal Street with Tay Street remaining closed at the Railway Bridge. The traffic lights have been reactivated at the Canal Street Junction to control flow of traffic in/out of Tay Street North. On street parking has also been reinstated and available to use within the available cul-de-sac.

We would like to thank the businesses for their patience and co-operation while we worked through this vital section of the project.

Almost done!

Taken from within the site compound in May 2025, the project is nearing completion with the site shortly due to handover to Perth & Kinross Council for reinstatement of the road

Shore Road Latest Update

Work on Shore Road is progressing well, with all the new sewer pipes now laid, and reinstatement of the road currently underway.

Shore Road Traffic Management

Access to Shore Road is currently via Marshall Pl > Edinburgh Rd (A912) > Friarton Rd.

The alternative route for HGVs only is still in operation via the roadway at the southern edge of the Lesser South Inch and will remain in place until the end of the project.

Entry and exit from the South Inch Car Park is from the south entrance on Shore Road via Friarton Road, utilising the previous entrance only. Please follow all diversion signs in place.

Please note that the South Inch Car Park is now Pay and Display as installed and operated by Perth and Kinross Council.

Pedestrian and cycle access will be maintained, including access to Moncrieffe Island via the railway bridge.

Local businesses remain open as usual throughout.

Yellow arrows indicate a diversion route to and from Shore Road via Marshall Place and the A912. Another arrow points to the 'Entry/Exit to South Inch Car Park,' which remains accessible despite the road closure. Key landmarks include Perth Skatepark and Moncreiffe Island Allotments.

Access to the South Inch Car Park is currently via Friarton Road while the north section of Shore Road is closed.

Community Engagement

We carried out a well attended information event at the Salutation Hotel in April 2023 to discuss the project with the Perth community. This event gave us the chance to show our information boards detailing the project and the necessary road closures that would be in place as well as answering any questions from the public.

Since then we have promoted the project and road closures significantly through use of news, radio, and social media advertising. We have also continued to regularly update our website with the most up to date project information.

The project team will continue to keep residents and businesses informed and respond to feedback throughout the delivery of the project, while a community liaison group was formed for the Tay St aspect of the project which allowed our team to regularly meet and have discussions with members of the community and stakeholders through the most impactful stage of the work.
