BuroHappold helps restore sluicing to Hayle Harbour
Hayle Harbour’s restored sluicing system is now operational, providing an environmentally and financially sustainable solution to the continuing battle against siltation of the navigation channels.
The system, originally installed in the early 19th century before the advent of mechanical dredgers, uses gates to capture the high tide in enclosed pools in the estuary, before releasing the water in a concentrated burst during the falling tide to flush out the channels. The system was discontinued and fell into disrepair following the cessation of commercial shipping in the 1970s. The sluicing system is one of the key facets of Hayle Harbour’s status as a UNESCO World Heritage site.
BuroHappold Engineering has played a pivotal role in the restoration, as part of the wider regeneration of the harbour, beginning in 2007 with the original masterplanning of the then near-derelict harbour. Our water engineers led the specification of the new sluicing infrastructure to gain planning and listed building consent, which combined with the leadership of our geoenvironmental engineers in the reuse of contaminated dredgings from the infilled channels to create flood defence platforms.
The new platforms on the old quay have enabled the development of a supermarket and new waterfront residential properties by creating land safe from the combined threat of storms and sea level rise.The iconic supermarket was the winner of the South West RIBA award, with enabling and structural designs by BuroHappold. A powerful combination of the new and the old to put the harbour back as the beating heart of the town.
