Mermaid Quay

We invested £2 million to upgrade to the sewer system in the Mermaid Quay area of Cardiff Bay. We explained at the time that we would need to return to carry out the final upgrades to the sewer, and the time has now come for us to do this.  

What did we do last year? 

We invested £2 million to upgrade the sewer system following reports of local internal flooding. This was caused mainly by the illegal discharge of fat, oil and grease (FOG) down the drains and other items being flushed down the toilet that build up in the sewer and cause blockages. Frequent cleaning to clear the blockages damaged the sewer in Mermaid Quay which needed to be replaced.

Work began in September 2018 and was carried out in a phased approach to minimise the impact on the local area. The work included repairing the original Victorian brick sewer, removing fats, oils and grease blockages from the sewer and installing a new sewer pipe on Stuart Street and Bute Street. 

Between September 2019 and December 2019, we removed 800 tons of fats, oil and grease – that’s the equivalent of 133 African elephants! Watch the video below to find out more.

What are we doing now?

We need to return to install a dosing kiosk outside the back entrance to Eli Jenkins at the top of Bute Street. This will help us manage the impact fats, oils and other greasy substances can have on our sewer network and ensure we continue to provide you with a first-class waste service for years to come. 

This work will begin on Monday 12th October and will be completed by mid-November. We will be working with Morgan Sindall to help us get the work done. They will be working Monday to Friday from 8.00am until 6.00pm. 

As we will only be working within a small section of Bute Street, the street will remain open while we carry out this work. However, we will need to make the street narrower for the safety of pedestrians and our workforce.


Stop the block 

This essential work needed to be carried out following incidents of local internal flooding caused by the illegal discharge of fats, oil and grease down the drains. This caused blockages in the sewer and frequent cleaning was required to clear these blockages, damaging the sewer in the process.

We can all play a part in ensuring that our sewers are kept free from fat, oil and grease. Click here for more information on how you can keep the wastewater pipes at your business flowing.
