Enhanced Resilience

The successful implementation of the drainage system enhanced the development's resilience against weather challenges, ensuring longevity, comfort, and safety for guests and stakeholders, and setting a precedent for effective stormwater management in challenging environments.

The Problem

The ambitious $82 million Hilton Hotel Development in Bournemouth posed a significant challenge - controlling surface water and potential floodwater on a challenging slope. With the development encompassing a 13-story 5-star Hotel, 8-story Hampton by Hilton complex, 45 apartments, and a 3-story underground car park, the project required an exceptionally versatile solution to manage excessive surface water run-off and withstand continuous car usage and the weight of the construction. 

The Solution

When faced with this demanding task, the contractor, McAleer and Rushe Group, turned to Wavin's drainage solutions. The Wavin Water Retention System Prime geocellular stormwater management unit emerged as the ideal solution for the development. With over 600 Wavin Water Retention System Prime units specified for the project, a 4,240f³ cellular attenuation tank was created below a restaurant, terrace, and entrance café area to effectively manage surface water.
