Urban Honolulu FAQ

How do shortage rules affect Waikiki hotels?

BWS stage-based restrictions tighten landscape irrigation, pool-deck washing, and non-essential use. Large hotels typically pre-file conservation plans to maintain tourist operations.

Can my condo still use recycled water for landscaping?

Yes. ROH Sec. 30-2.3 allows non-potable sources. Many Ala Moana and Kakaako towers pipe in reclaimed water for common-area irrigation.

Waipahu FAQ

Are Waipahu yards always on watering-day restrictions?

No. Day-of-week schedules activate only when the Board of Water Supply declares a numbered shortage stage. Otherwise, standard conservation practices apply.

Can Waipahu farmers near Kunia use non-potable water?

ROH Chapter 30 and BWS policy encourage non-potable use where available. Agricultural irrigation typically uses separate ditch systems or dedicated non-potable connections.
