Become Rain Ready!

Get rain barrels, a rain garden, or a tree installed for FREE

This is a new incentive program, led by the City and County of Honolulu and Mālama Maunalua, that brings rainwater capture solutions to Oʻahu residents.

The program covers the cost of supplies and installation of rain barrels, a rain garden, or a native tree.

Funds are limited. Apply while available.

Rainwater capture projects are a cost-effective way for residents to:

  • Protect O‘ahu’s precious groundwater

  • Reduce flooding in our communities

  • Mitigate stormwater pollution in streams and the ocean

  • Potentially soak up savings on water bills!
