Municipal applications

Damaged socket joints characterize the picture of pipeline damage. Root ingrowth, pressing groundwater, socket misalignments, axial displacement and non-functional seals often lead to leaks in wastewater systems.

Leaks in wastewater systems pose many hazards to people and the environment.

Infiltration, water seeping into the pipeline from the outside, usually also transports soil material into the pipeline, creating cavities and washouts that statically influence the bedding and load-bearing capacity of the entire pipe or manhole system. In the worst case, day bridges occur.

Furthermore, groundwater that enters the wastewater system must be processed at high cost in the wastewater treatment plant. Often so much “extraneous water” accumulates that the wastewater treatment plants are overloaded. In some cases, operation has to be throttled back or stopped altogether.

Exfiltration, i.e. water seeping into the ground from a leaking pipe, poses an enormous threat to our groundwater. Here, too, washouts can occur when water leaks from defective connections.

In addition to the damage to the bedding, depending on the nature of the wastewater, the environment or the groundwater can be irreversibly damaged.

These are part of the reason why wastewater associations and municipalities have decided to completely weld their wastewater systems.

Many municipalities and wastewater associations have already opted for welded wastewater systems.

And for good reason.


Basically, welded pipe joints are used in the following areas:
