Marlborough is one of Wiltshire's most attractive market towns, renowned for its exceptionally wide High Street — one of the widest in England — and the prestigious Marlborough College. The town sits in the Vale of Pewsey at the confluence of the River Kennet's headwaters, surrounded by the chalk downland of the Marlborough Downs.
Marlborough's chalk geology is a defining characteristic of its drainage landscape. The town sits on and immediately adjacent to chalk that is highly permeable, creating conditions quite different from the clay areas of central Swindon. Groundwater levels in Marlborough can vary significantly between dry summers and wet winters, and rising winter water tables can infiltrate drainage systems — causing apparent surcharging even when there is no blockage present.
The River Kennet, which rises in springs near Marlborough, passes through the town and can flood during significant rainfall events. The Kennet's small catchment means it responds quickly to heavy downpours, and the river's interaction with the town's drainage network creates surcharging risk in low-lying areas near the river.
Marlborough's historic buildings — including properties associated with Marlborough College and the old coaching inns along the High Street — have drainage systems that reflect the town's centuries of occupation. Brick-built culverts, stone channel drainage, and Victorian clay sewers underlie the historic core, while the residential areas on the town's margins feature more modern drainage.
Call-out to a period property near Marlborough College: The owners reported that every wet winter their ground-floor drains ran slowly and gurgled, despite the drains running freely in summer. CCTV investigation confirmed groundwater infiltration — the camera revealed clear water flowing through joints in the old clay pipe system beneath the garden, effectively filling the drain from outside. The infiltration was occurring through multiple joint failures spread along a 15-metre pipe run beneath a lawn area, where seasonal shrinkage and swelling of the surrounding soil had gradually opened the joints. We carried out a full relining of the affected pipe run, sealing all joints and restoring watertightness. Result: the following winter saw no slow drainage for the first time in the owners' 12 years of ownership. Tip: if your Marlborough property experiences seasonal slow drainage that improves in summer, groundwater infiltration through cracked or separated pipe joints is the most likely cause — and pipe relining is the permanent solution.
Swindon's unique geology and rapid expansion have created specific drainage challenges. Here are the most common causes of blocked drains across the town.
Emergency ServicesA drain emergency can be stressful. Knowing what to expect when you call for help can make the situation much easier to manage.
Drain SurveysSwindon sits on a fascinating but challenging mix of chalk, greensand, and Jurassic clay. Understanding the geology helps explain why drainage problems are so common here.
Yes, significantly. Chalk is permeable, and winter groundwater rises in chalk areas can be dramatic. When the water table rises above the level of drainage pipe inverts, groundwater infiltrates into the drainage system — filling pipes with clean water that dilutes foul drainage and reduces capacity. This can cause apparent surcharging even when there is no blockage. Properties in low-lying areas near the Kennet are most affected. A CCTV survey during winter can identify infiltration points.
The River Kennet and its headwater streams can flood in Marlborough during significant rainfall. The river responds quickly to heavy rain on the chalk downs above the town. Properties near the river and in the lower parts of the High Street area are most at risk. Thames Water and the Environment Agency both monitor the river, and the EA's flood maps show at-risk properties in Marlborough.
Marlborough is approximately 12 miles from central Swindon. We can typically reach the town within 75 to 90 minutes for emergency callouts. For non-emergency work, we offer flexible appointment times to suit your schedule.
