Today Carnival Cruise Lines unveiled the cruise industry’s most exhilarating and unique water slide the 104-foot-long “DrainPipe”, which will be aboard the new Carnival Dream when the vessel enters service September, 21, 2009.

The DrainPipe – which is comprised of a giant funnel attached to an enclosed spiral water slide to providing riders with a thrilling conclusion to their journey – will be a central component to the ship’s sprawling WaterWorks aqua park.

WaterWorks will also feature a four-deck-high, 303-foot-long enclosed corkscrew water slide – the longest in cruising – along with twin dual-lane 80-foot-long racing slides and water spray apparatus such as squirting fountains, splash zones, and dump buckets.

WaterWorks is just one of the many innovations featured on the 3,646-passenger, 130,000-ton Carnival Dream — the biggest Carnival ship to date.

Video footage of Carnival employees testing the new DrainPipe attraction is available on Carnival’s news blog.
