HONOLULU (HawaiiNewsNow) - According to the Honolulu Board of Water Supply, several communities across Oahu either lack or are without fire hydrants. Meanwhile, the Honolulu Fire Department says there are many practices already in place for their protection. When it comes to determining the appropriate fire hydrant spacing, BWS says it's all about zoning. According to BWS standards, there should be a hydrant every 250 feet in areas zoned multi-family residential, commercial or industrial.
