The Waikiki Aquarium hosted a free rain garden workshop from 6 to 7 p.m. on Tuesday, March 25.
Rain gardens help stop water runoff, the greatest source of pollution of Hawaii's streams and coastal waters, by allowing storm water from impervious surfaces to collect, briefly settle, then infiltrate into the ground.
They mimic natural processes by treating and infiltrating storm water into the ground and evaporating it back into the air.
Todd Cullison, executive director of Hui O Ko‘olaupoko, provided instruction on how to create a do-it-yourself rain garden. A free manual is also available at www.huihawaii.org/rain-gardens.html.
The workshop, supported by the state Department of Health's Clean Water Branch and Hardware Hawaii, brought awareness to the importance of natural vegetation designed to absorb and filter rainwater from heavy tropical storms.
Visitors to the aquarium during the month of April also receive 100 tote bags with rain garden information and instructions for teachers to give their students.
The Waikiki Aquarium itself will also be home to a rain garden to be revealed at its annual Mauka to Makai Event on April 19.
