Westbank Quadrant Sewer Upgrades
Project Overview
We are carrying out work in the Westbank Quadrant area of Glasgow to improve the sewer network and reduce the risk of items such as wipes and sanitary products entering the River Kelvin during heavy rainfall events.
This work is being carried out by our alliance partner Caledonia Water Alliance.

What We Are Doing
Following on from upgrade work previously carried out within the grounds of Hillhead Primary School, we are now moving on to the final phase of our improvement work within the Hillhead area of Glasgow.
This final section of works involves connecting the sewer from Hillhead Primary School to Gibson Street.
We will be delivering this project in three phases, each following on from one another:
- Phase 1: This will include the sewer installation within the school grounds and past the entrance to the underground car park. Access to the underground car park will be unavailable during this phase, which has been scheduled during the summer holidays to minimise disruption to school operations. We expect this phase of works to take approx. six weeks.
- Phase 2: Once phase 1 is complete the underground car park will reopen, and sewer installation will progress onto Otago Street, adjacent to the school entrance. Full access to the school will be maintained throughout.
- Phase 3: This will follow from phase 2 and will involve the connection of the new sewer to the existing network on Gibson Street. This phase will require temporary four-way traffic management. Dates for these works will be confirmed nearer the time.
Work began on Friday 26 June 2026 and is expected to be completed by March 2027.
To allow this work to be carried out safely and maintain traffic flow, temporary parking restrictions will be in place on sections of Otago Street and Gibson Street throughout this project, starting from Monday 29 June 2026. The existing one-way system on Westbank Quadrant and Otago Street will remain operational.
Why We Are Doing It
These sewer upgrades will help improve the performance of the local sewer network and reduce the risk of items such as wipes and sanitary products entering the River Kelvin during heavy rainfall events.

Latest Update - August 2026
Our team on site have worked tirelessly throughout the school summer holidays to lay the new sewer pipe which goes across the entrance to the school's car park.
The car park has now reopened in time for the school's return and we are now working on Phase 2 of the project, which involves laying the new sewer pipe further along Otago Street towards Gibson Street.
Parking restrictions continue on Otago Street during this phase of the upgrades.
We will be hosting an information event on Monday 17 August 2026 at Hillhead Primary School Hall, with a drop-in session between 3:15pm and 5:15pm.
This will provide an opportunity for members of the community to speak with the project team and find out more about the works.
We would like to thanks all residents, businesses and road users for their patience and understanding while we complete these essential upgrade works.
