Glynleigh Sewer is a river in Hailsham, Wealden District, East Sussex, England. Located partly in the Pevensey Levels, Glynleigh Sewer joins Hurst Haven to form the Pevensey Haven.[1] [2] The river forms much of the boundary between the civil parishes of Westham and Hailsham.[3]
Glynleigh Sewer rises from a drainage basin in farmland north of the A27 road in Hailsham, receiving most of its waters from Marland Sewer. Glynleigh Sewer then flows a southerly course, receiving the waters of Drockmill Hill Gut, after which it flows into the Pevensey Levels which is where it joins Hurst Haven to form the Pevensey Haven.[3]
