Drainage Services in Cwmbran

Cwmbran was designated a new town in 1949 and much of its housing was built in planned phases from the 1950s through to the 1980s, giving it a more consistent drainage layout than many older Welsh towns. Estates from the earliest phase, around Fairwater and Pontnewydd, typically use clay or early concrete pipework, while later development towards Llanyravon and Greenmeadow introduced plastic drainage systems. The underlying ground is a mix of clay and shale typical of the wider valley, which holds moisture and can lead to gradual settlement affecting older pipe joints.

As a planned town, Cwmbran generally has separate foul and surface water drainage on its later estates, though the earliest post-war development sometimes retains combined systems now reaching the end of their design life. Extensive street tree planting, a deliberate feature of the new town's landscaped design, means root ingress into older clay pipework is a recurring issue in the more established residential areas. The Afon Lwyd and several smaller streams running through the town mean low-lying sections can have a locally raised water table after sustained rain.

Our approach in Cwmbran starts with a CCTV survey to determine the age and condition of the drainage system relevant to that particular phase of the town's development, since pipe materials and layout vary noticeably between estates built decades apart. High-pressure jetting clears silt and grease from older combined sections, and no-dig relining repairs cracked or root-affected clay pipe without disturbing the town's characteristic landscaped gardens and green spaces. Later plastic-piped estates generally need less intervention but still benefit from periodic inspection.
