Haymarket Terrace Sewer Upgrade

Welcome to the Haymarket Terrace project page, where you will find all the key information about what we are doing in Haymarket Terrace, Edinburgh and can keep up to speed with the latest progress throughout the project.

We are approaching half way point in our essential project to build capacity into Edinburgh’s sewer network and ensure the waste water cycle is fit for the growing demands of the Capital.

Work is progressing well and we continue to work with our contract partners and other utility providers to ensure the work causes as little disruption and inconvenience to the public as possible.

We would like to thank the local community for their patience and understanding whilst this work is carried out.


Public meeting Feb 2018:

Scottish Water staff attended a public meeting with residents and business owners in the Haymarket area to discuss the ongoing work to alleviate sewer flooding in the area and ensure the waste water cycle is fit for the growing demands of the city.

Three members of Scottish Water staff gave updates on the project to fit a new modern sewer infrastructure and took questions on a range of issues including road works in the area. They were joined by a representative from Edinburgh City Council who talked about traffic diversions in place while the works continue.

Around 30 people attended the event held in a Haymarket café and chaired by Christine Jardine, MP for Edinburgh West.

They heard that:

  • 114 metres of sewer works had now been installed with a further 22 metres to be fitted
  • Four more manholes will be constructed
  • Two sewer connection chambers have yet to be constructed 
  • Scottish Water and its alliance partners will continue to liaise and work closely with residents and local businesses in the area
  • Work is due to finish this summer

The Haymarket project is part of £30 million of infrastructure improvements being carried out in Edinburgh as part of Scottish Water's 2015-21 delivery plan.

Update of works:

  • Phase 1 – near the Apex Haymarket Hotel – Main site compound will remain through to completion of the works, with new pipe line connection on-going
  • Phase 2  - between Haymarket Yards and Magdala Crescent junctions, the longest section of the works is continuing with 48m constructed of the main pipe laying work
  • Phase 3 – between Roseberry Crescent and Haymarket Yards (west bound lanes), ~ 48m of pipework laid, to resume upon completion of Phase 4.
  • Phase 4 - by Haymarket railway station at Roseberry Crescent Junction - SGN is carrying out diversions in the area due to last until the end of March and after this a manhole will be built to connect the old to the new pipe line.


Facts and figures update:

A total of 96 metres of 1.2m diameter sewer pipe have been laid since the project began, from a total length of 250 metres

The project team have found many uncharted services in the work area. A high tech vacuum excavator is being used to reduce the first stage of digging – done to detect any uncharted utility services - to 1.5 metre below ground level. This makes it far less likely to strike utility service lines which can impact on the local community and cause delay.

The excavation work has uncovered original Victorian-era sewers in the area. It has also exposed parts of the city’s original tram line and in these areas workers have to break out large areas of concrete and steel beams.

We are continuing to work closely with local businesses and communities and our representatives are always available. Local businesses will remain open during the work and tram services are unaffected

We are investing £2.5m in this project to increase network capacity and help alleviate sewer flooding in the area and plan to complete early summer 2018.
