28. Water: Water from the County of Hawaii Department of Water Supply is on site. The water source is from an 8" mainline off Wainaku Street. There are two service lines that are upon parcel 002, 1) 2" Potable water with service meter, and 2) a dedicated Fire Protection service line. Both lines begin at parcel 002, crossing the lot then proceeding under H-19 in a concrete culvert easement granted in favor of the parcels from the State Department of Transportation. Fire protection, life safety, and appliances were installed in the Wainaku Building following the Fire Code and the manual fire alarm levers, automatic sprinkler systems and smoke alarms are all connected to a server that automatically notifies the Fire Department if any of these systems are activated.
