Drainage Services in Troedyrhiw

Troedyrhiw sits close to the River Taff at the bottom of a steep valley, and its terraced housing, built for the local mining and ironworking population, occupies a narrow strip of relatively flat ground between the river and the hillside. This proximity to the Taff means the local water table can rise close to the surface after heavy rain, affecting the performance of the community's older clay drainage and increasing the risk of surface water backing up into shallow pipe runs.

Many of the terraced streets here retain combined sewers dating from the original Victorian-era construction, and the steep catchment of the surrounding hills means rainfall reaches the valley floor quickly, putting pressure on this older infrastructure during storms. Housing on slightly higher ground towards Cefn Coed uses more modern plastic pipework, generally coping better with the area's periodic heavy rainfall events.

In Troedyrhiw we start with a CCTV drain survey to determine whether high water table conditions linked to the Taff, root ingress, or a structural pipe fault is causing a blockage. Jetting clears the majority of issues without digging, and no-dig lining lets us repair cracked or displaced pipework beneath these riverside terraces without extensive excavation in the limited space between properties and the valley floor.
