Pratt Aquatic Center and Waterhouse Pool

The C. Dudley Pratt Aquatic Center, at the ground level of Hemmeter Fieldhouse, is comprised of the Elizabeth P. Waterhouse Pool and the facilities that support the Punahou swimming program including the Harry Steiner Pool Office.

With a depth of at least 9 feet for its entire length, the Olympic-sized 50 meter by 25 yard Waterhouse Pool is the largest of any school in the state of Hawai'i (including the University of Hawai'i), at more than a million gallons.


The original 75 by 35 foot pool was dedicated in 1922 and named to honor the memory of student Elizabeth P. Waterhouse. The Dudley Pratt Aquatic Center and replacement pool were built in 1981 as part of a massive Physical Education and Athletics Complex renovation, and the new pool was designed to be "fast" and built at 50 meters by 25 yards to accommodate metric competition.

Upon its completion, Peter Powlison, former teacher, later Trustee, and legendary competitive swimmer dove into the new Waterhouse Pool and swam the first lap in front of a cheering Punahou crowd.
