This increasing number of sewer blockages is being caused by fat, wet wipes and other 'unflushables' and whilst public awareness has grown significantly, the problem is unlikely to go away, which means that sewer jetting will always have an important part to play in the flow of the UK's sewerage system.
Think it won't affect you? Think again - Thames Water discovered a 130 tonne fatberg in 2017 under Whitechapel in London, which took a team of eight people, using high-pressured jetting equipment several weeks to break down. SInce then, many more have been discovered throughout the UK sewerage network.
The argument for using precast concrete drainage products over other drainage materials has always been a compelling one, as the environmentally friendly, sustainable, heat resistant, precast concrete continues to gain strength throughout its service life and is able to withstand the jetting requirements of BS 5911.
With leading precast drainage manufacturers, Marshalls CPM offering a 120-year design life on all of their precast concrete drainage products, theirs is currently one you can trust in.
In fact, Marshalls CPM have a 525mm concrete pipe at their Mells works in Somerset that was originally installed alongside the old castle in Norwhich in 1891 and was excavated in June 1991. It shows no signs of deterioration and is structurally sound and when tested, the pipe satisfied the requirements of the current standards for concrete pipes, even though there were no standards when it was originally manufactured in 1891.
During the summer of 2018, Marshalls CPM supplied flexible jointed concrete pipes and manholes to a £15m new sewer project in Frome Valley, Bristol that included the replacement of an existing pipe run to increase capacity for new housing developments in the area.
This work included digging up an old pipeline, which included 525mm rocker pipe that was manufactured at the Marshalls CPM works in 1987. The rocker pipe is in perfect condition.
