Cardiff North


We’re investing nearly £8.5 million to improve the way our wastewater system works in the north of Cardiff. This is to ensure we continue to provide customers with a first-class waste service for years to come.

This investment involves various activities including replacing, cleansing and relining sections of the wastewater pipe between Tongwynlais and Hailey Park in Cardiff. This work is essential in order to reduce the CSO spills to the River Taff, increase the network capacity and ensure that we help protect the local environment for years to come.

This work is taking place in three areas – Hailey Park, Ynys Bridge and near Iron Bridge Road in Tongwynlais. We’re working with Morgan Sindall to help us get this work done, so you may notice their vehicles in each of these areas. Here is an overview of what we’re doing:

Hailey Park - Cardiff

We have now completed the work involving cleaning the sewer pipe that runs through Hailey Parkand reseeded our working area.

Ynys Bridge

We’re currently working in Ynys Bridge to lay sections of a brand-new wastewater pipe. This work is currently taking place on the private land near Gelynis Farm, but you may notice some of our contractor’s construction vehicles travelling along Ty Nant Road and Gelynis Terrace to access our working area. This work will be completed by the end of September 2021.

Tongwynlais

Iron Bridge Road: We’re laying a brand-new wastewater pipe within the private land either side of Iron Bridge Road, as well as cleansing sections of the existing pipe. This work started on Monday 14th September and will be completed by the end of September 2021.

We’ve also completed the first phase of our work within the private land north of our site compound. This involved carrying out some tunnelling activity to lay the new wastewater pipe. We’re now working on the upgrade of the Combined Sewer Overflow (CSO).

To be able to access the working area, heavy construction traffic will be travelling down Iron Bridge Road between 9.30am and 3pm, avoiding peak school times. Where possible, we’re kindly asking residents to avoid parking along the narrow sections of the road to help us minimise any potential traffic disruption in the area.

M4 and Longwood Drive

We will be cleaning sections of the sewer pipe within the vegetated area between the M4 and Longwood Drive, Tongwynlais. Working closely with the local authority and ecologist, we have carried out most of the vegetation clearance that will allow our work to be carried out safely.We will be continuing the vegetation clearance from the 19th July.

Our main construction work will begin during week commencing the 9th August, and from this point until the beginning of September there will be Give and Take traffic management in place. There will also be times when we will be using traffic cones and signs to help monitor the traffic and ensure sure we can access our working area safely. As long as everything goes to plan, the work should be completed by the end of September 2021.

Working during Covid -19

During this time, we will continue to follow Government guidelines and would like to thank customers for ensuring they maintain a safe distance from our colleagues. We know this is a very challenging time but please be assured that we are – and will continue – to do everything we can to continue providing our essential services.
