Catalyst’s Head of Technical and Network, Paul Duddle, explains how household drainage systems work, how key faults can develop, and the main techniques available to find and diagnose these faults.
The sewer coding system is used to identify the location and structure of a pipe, and defects it may have. Our video shows how a drainage engineer uses sewer coding during a drain survey.
This video shows the common causes of these defects, including pipe cracking and pipe collapses.
A joint displacement occurs where two of these sections come apart. Our video explains the different types of joint displacement commonly found in sewer systems.
It also explains how they form and why identifying the type and extent of cracking is often important when selecting the best way to carry out a repair.
They allow underground pipes to be stepped down to main sewers so wastewater runs smoothly. This video gives more information about why they are installed and how they work.
This video explains the importance of planned and preventative gully maintenance to prevent blockages and potential subsidence problems.
Our video explains why carrying out surveys to establish where water comes from, where it goes is and who is responsible for it, are essential for good drain maintenance.
A quick and accurate way to do this is to use a CAT and sonde, which use radio waves to pinpoint underground locations. Our video shows CAT and sonde technology in action.
This process is called pipe root ingress. Our video shows the three main types of root ingress: fine root ingress, tap root ingress and root mass.
For example, water may be seeping through displaced joints or cracks. Our video shows how carrying out a water drop test can quickly establish if pipes are carrying water properly or are leaking.
