If the problem is more serious, then things get more complicated. As sewerage systems are a civil matter, we have a specific team at Kwikflow that deals with these that are registered with the civil authorities in order to carry out repairs. When there is a more catastrophic failure or collapse, an excavation and sewer line replacement may well be necessary, and in these circumstances we will of course disrupt the local area. In every case of this we will do everything we can to keep disruption to a minimum, in terms of noise levels, pollution from our work, disruption to roads and traffic in the area, and speed of works to not cause businesses around the area to shut down for too long. We also have the option of patching if the collapse is only in a small part of the pipeline and is easily accessible through a manhole or access point.
