Drainage in Pangbourne
Pangbourne is a Thames-side village where the River Pang meets the Thames. Kenneth Grahame, author of The Wind in the Willows, made his home there. Because the village sits in a narrow valley between the Berkshire Downs and the Chilterns, water from a wide area runs into a small space.
The Thames and the Pang shape Pangbourne's drainage. The Thames runs along the north edge of the village, and Whitchurch Bridge crosses it to Whitchurch-on-Thames in Oxfordshire. The Pang, a chalk stream that rises in the Berkshire Downs near Compton, runs through the village and joins the Thames at Pangbourne Meadow. Because the two rivers meet here, the village can face flood risk from both at once, and it has seen serious floods in past winters.
Chalk lies under this part of the Thames Valley, with river gravel and silt on the valley floor. The chalk lets water through, so it works as a natural store that takes in rain from the Downs and releases it slowly through springs and streams like the Pang. When the chalk is full, usually after long winter rain, ground water rises sharply. As a result, cellars and basements can flood from below even while the rivers stay in their banks.
The old village core around the High Street, Reading Road and St James the Less Church mixes Georgian, Victorian and Edwardian homes. Their drains have changed many times over the years. Since the lanes are narrow and the plots close together, many homes share drain connections and access is tight.
Pangbourne College, which fills large grounds on the hillside, and the bigger homes along Shooters Hill and the roads up to the Downs, sit higher. These homes drain better thanks to the height and the chalk below. However, they face long pipe runs through sloping ground, tree roots, and chalk that can make digging costly.
Pangbourne Meadow and the low ground where the Thames and Pang meet work as a natural flood plain. Because homes there face a high flood risk, they need drain plans that allow for floods.
Thames Water's sewers serve a small community here, yet they face large challenges from the high water table, two rivers and the chalk. During wet spells, ground water can seep into old sewer pipes and use up capacity before any foul water arrives. This leaves less room for the sewer to do its real job.
Water is never far away in Pangbourne, so good drain care is a constant job. We understand chalk ground, flood risk from two rivers and the needs of an old Thames-side village.
