An emergency pipe repair carried out on a leaking 450mm wastewater pipe at a Water Treatment Works in the United Kingdom

450mm Wastewater Pipe Live Leak Repair

Major infrastructure improvements were being carried out on a Water Treatment Works in the United Kingdom when contractors drilled through a 450mm wastewater pipe, resulting in a dangerous pressurised leak of contaminated water which required a rapid emergency repair.


The contractors had believed that the wastewater pipe in question was decommissioned and due for removal. In fact, it was one of the most important pipes on site as it was connected to all the waste treatment ponds.

Once the pipe was breached, there was no feasible way to turn off the pressure. To add to the problems, a large amount of wastewater was now escaping from the damaged pipe, with potentially costly and embarrassing consequences. As a result, a rapid emergency wastewater pipe repair was required.


The Water Treatment Works got in contact with Sylmasta who, within an hour of receiving the call, were able to deliver to the site all the equipment needed to permanently seal the leak.

Wrap & Seal Pipe Burst Tape was used to seal the live leak. SylWrap Pipe Repair Bandages were then applied over the top of the Wrap & Seal for a permanent solution. The wastewater pipe repair was completed in less than 30 minutes.

Both Wrap & Seal Pipe Burst Tape and SylWrap Pipe Repair Bandages can be purchased in one SylWrap Universal Pipe Repair Kit. For users who may need to carry out regular repairs of this type, then the SylWrap Pipe Repair Contractor Case contains enough products to fix multiple leaks and can be stored easily on a van should emergencies arise.


The repair was carried out at a cost of less than £300, which included spare SylWrap Bandages should the site suffer any other unexpected problems during the improvement works.

This was a drop in the ocean compared to how much a solution would have cost without SylWrap products. The site may have been forced into a shutdown to isolate the pipe so that a replacement could have been fitted.

A combination of a new pipe, the labour costs of installing it and the associated loss of earnings during the shutdown could have turned the whole process into an expensive affair running into tens of thousands of pounds.

The speed of a SylWrap repair also prevented a serious environmental issue developing. This could have been damaging in monetary terms through the clean up operation and possible fines and for the reputations of both the Wastewater Treatment Works and the contractor involved.


Given how quickly and efficiently SylWrap products prevented this potentially costly wastewater leak getting out of hand, the site manager was understandably delighted with the repair provided by SylWrap.

He emailed a few days later with the pipe now back in full working order to say, “Thank you so much, the pipe repair worked a treat.”
