Improvement of the Ala Wai Canal

Abstract

The Ala Wai Canal flushes poorly due to its length to width ratio; this, combined with the high nutrient levels discharged into it, causes a persistent problem with water quality. As a result of this study we believe that the most cost effective means of improving the water quality in the Ala Wai Canal is a conventional pumping system. A pipe running the length of the canal fed by an electric powered pump near the entrance will exchange the water sufficiently rapidly so that recreational activities could be conducted in the canal.
