Tillingbourne waterfall restoration Wotton Estate

The Tillingbourne waterfall and pools wind through the Broadmore Valley and are a distinctive historic feature of the Wotton Estate. Constructed in 1740 by London merchant and architect Theodore Jacobsen, the waterfall forms part of an engineered water system that reflects the ingenuity and ambition of 18th-century landscape design. 

Historically, the Tillingbourne stream played a crucial role in the industrial heritage of the Surrey Hills. Along its course, the river once powered numerous mills, supporting local industries and shaping the development of surrounding communities. Today, while the mills have long since fallen silent, the waterfall remains an iconic and much-loved feature, enjoyed by walkers exploring the valley and providing valuable habitat for wildlife. 

Over time, the waterfall and its surrounding structures became increasingly obscured and damaged by overgrown vegetation and invasive cherry laurel, which threatened both visibility and long-term stability. In addition, a large dead pine tree posed a significant risk to the waterfall and surrounding area. Fallen trees had also damaged the leat the man-made channel that supplies water to the waterfall causing water to escape through breaches rather than flowing naturally over the falls. 

The Wotton Estate successfully applied for funding to carry out a programme of restoration works. Phases 1 and 2 of the project focused on clearing surrounding vegetation, treating invasive laurel, safely removing the dead pine tree, and repairing the leat at multiple points along its length. The entire channel was cleared, allowing water flow to be fully restored to the waterfall. 

As a result of these works, the waterfall is once again visible and flowing as originally intended. The project has enhanced the experience for walkers, safeguarded an important historic feature, and improved access for the Estate’s team to carry out ongoing maintenance and conservation. 

The Tillingbourne waterfall is currently in the process of being formally recorded on the Historic Environment Record (HER), helping to ensure its recognition, protection, and preservation for generations to come.
