Drainage in Ringwood
Ringwood is a Hampshire market town in the Avon Valley, sitting at a point where the River Avon broadens and slows as it approaches the southern fringes of the New Forest. The town's drainage challenges are shaped by two dominant factors: the River Avon floodplain to the east of the town, and the New Forest heathland soils that underlie the western residential areas. These two very different geological and hydrological environments create distinctly different drainage experiences for properties on opposite sides of the town.
The River Avon at Ringwood is a wide, chalk-fed river that rises and falls relatively predictably with rainfall in the Wiltshire and Hampshire chalk downlands. However, during extended wet periods—as seen in the winter of 2023–24—the Avon floodplain around Bickerley, Blashford, and the lower-lying parts of the town can hold substantial standing water for weeks at a time. Properties on Bickerley Green and roads adjacent to the water meadows face genuine flood risk and experience the same groundwater-infiltration drainage problems seen across the Avon Valley: saturated soils push groundwater into any drainage defect, and the combined sewer network in the older parts of town has limited capacity to absorb this additional volume.
The western residential areas of Ringwood—Poulner, Hightown, and Ashley Heath—sit on New Forest gravels and sandy heathland soils. Here, drainage is the opposite extreme: the freely-draining sandy substrate means surface water disappears quickly but the soil can move and settle, causing pipe misalignment over time. Post-war housing in Poulner and Hightown uses a mixture of clay and early uPVC drainage, and properties from the 1950s and 1960s are now at an age where drainage surveys reveal the cumulative effects of decades of minor ground movement—sagging pipe runs, joint separation, and root intrusion from the mature gardens that are characteristic of New Forest edge settlements.
Ringwood town centre, including the older properties around the Market Place and Meeting House Lane, contains Georgian and Victorian buildings with drainage infrastructure of varying age and condition. Commercial properties around the Furlong shopping area and along Southampton Road need to manage trade waste water effectively, and we regularly service grease traps and commercial drainage in these premises. Our Ringwood engineers work across both the floodplain-adjacent east side of town and the sandy heathland west side, bringing appropriate expertise to each environment.
