Location: Marble Arch
Duration: 2 week
Sector: Commercial

Job Specifications:

We were asked to install a new sewer connection on site to provide temporary toilets for a pop-up theatre. We were required to connect the system to the nearby Thames Water Sewer. We also needed to implement a traffic control system due to the high levels of traffic and congestion on the roads.

Our client:

Underbelly is a UK-based live entertainment company. Their events and festivals division operates one of the largest stages at the Edinburgh Festival Fringe, running across 19 venues and four sites with a programme of 146 shows.

What work was undertaken?

Due to the aged state of the Victorian sewer connections on site, we were unable to make the connection as planned. Instead, we needed to provide an urgent contingency plan. Customers were due to start using the space just weeks after drainage challenges were spotted.

Our solution was to install above-ground holding tanks which could hold commercial waste on a temporary basis. Our combination tankers were then scheduled to empty these tanks regularly required.


The main challenge we had to navigate was that work was being completed in an area that was high in footfall and vehicle traffic. We needed to implement traffic management strategies that didn’t cause major disruptions to the public.


Underbelly was satisfied with the consideration and flexibility we demonstrated whilst we completed work for them. They invited us to their other locations to complete similar sewer connections in the future.
