Taking care of your sewer network in Greenock

Watch the latest video of the investment work here.

What we are doing?

We are taking care of the waste water services in your community by upgrading the sewer pipes to help alleviate flooding in the area. This £2.8m investment project began in January 2018 and, once completed, will help alleviate flooding that occurs at the Oakmall Shopping Centre during periods of severe rainfall. 

What does the project involve?

Forty-seven metres of pipework is being installed to upgrade the existing sewer network, improve the water flow, and reduce the risk of flooding in the Oak Mall Shopping Centre and surrounding areas. The work is being carried out by Scottish Water’s alliance partner Amey Black and Veatch. The work is expected to take approximately 9 months for completion.

Where is the work taking place? 

Our current work is being carried out on the existing network in three separate locations:

Bullring Car Park

Most of the work within the Bullring car park has now been completed and the car park is in operation. 

B&M Car Park 


Work is ongoing to install two Combined Sewer Overflows within the car park of the B&M Home Store - located at point 1(Westburn Street) and point 2 (Inverkip Street) on the map below. Workers will use the open cut method to install pipework to connect the two chambers.

Please note:
•Parking has been suspended in some parking bays within the car park. Works have been located away from the shop entrance to help minimise disruption for customers and staff. 
•Diversion of existing utilities required at the start of the project which will require traffic management on the A78 Inverkip Street.
•Full pedestrian access will be maintained at all times.
•You may notice some noise and vibration from the works. 

Plan of 3 locations of work:


Traffic lights to remain until approx. 12th October 2018. 

Our works are progressing to improve Scottish Water’s waste water infrastructure to help tackle flooding around the Oakmall Shopping Centre in Greenock town centre.

The guided tunneling machine used to tunnel underneath the roundabout to connect the new sewer to the existing sewer has experienced difficulties underground.

We are now having to hand dig this section which is extending the period that the traffic lights are required for.

The four way traffic light traffic set up at the roundabout with Inverkip St (A78) / Sir Michael St / High St for is to remain until approx. 12th October 2018. 

How this may affect you

• Traffic lights set up at the roundabout with Inverkip St (A78) / Sir Michael St / High St / exit to Greenock Bus Station to remain until approx. 12th October 2018..
• A traffic contraflow system on Inverkip Street will continue to be in place with 4 lanes reduced down to 2 (one lane open each way).
• Drivers are advised to allow extra time for journeys as significant delays are expected.
• Pedestrian access will be maintained - please follow diversions in place. The pedestrian crossing near the roundabout has been replaced with a temporary crossing.
• All local businesses will remain open as usual while we are working. Please help support your local businesses. 
We are sorry for the extension of this phase and any inconvenience this essential work may cause.
