A funfair ride which closed after a teenager was killed when she fell 100ft from its top is to reopen next month.
Safety fittings on the Hydro ride have been improved
Hayley Williams, 16, died at the Hydro water ride in Oakwood Park in Pembrokeshire, in April 2004.
The ride remained closed last year while the Health and Safety Executive and police investigated the accident.
Park director Paddy McNamara said Hydro boats' interiors had been replaced and had been fitted with over-the-shoulder restraints with an interlock mechanism.
Dyfed-Powys Police said the investigation into the accident is ongoing, but confirmed that the Health and Safety Executive had released the ride back to Oakwood.
Hayley had been with her mother and sister on holiday at the family's caravan in Pembrokeshire when she fell.
She was airlifted to hospital after the fall from the ride but later died.
A 10-year-old boy who was also on the ride was treated for head injuries, as a result of being hit by Hayley as she fell.
Around 100 people have been interviewed in the police investigation and an inquest into Hayley's death has been opened and adjourned.
The 121ft Hydro ride, opened in June 2002 at a cost of £2.4m, is described by Oakwood as "Europe's fastest and wettest" water-coaster.
Its 24-seater boat drops down a near-vertical chute into a plunge pool at 50 miles an hour, creating a 45-foot wave.
Mr McNamara said: "It was appropriate that Hydro remained closed last year, but we are pleased it will re-open as it has always been an extremely popular ride at Oakwood and it has been enjoyed by hundreds of thousands of riders in the past.
"As with all rides at Oakwood, Hydro ride operation and design is signed off as safe by independent certifying engineers before it is opened to the public.
"We do, however, acknowledge the need to provide additional reassurance to future riders and are quite sure the new system will do this."
