The Honouliuli Water Recycling Facility produces R-1 recycled water for irrigation in Ewa, and customers connecting to the recycled water system pay reduced rates under BWS rules.
BWS partners with the city Department of Environmental Services on the Honouliuli Water Recycling Facility, which produces R-1 quality recycled water from treated wastewater. R-1 water is approved by the State Department of Health for unrestricted irrigation of golf courses, parks, schoolyards, and landscaping in West Oahu. Connection requires a separate purple-pipe service, signage in non-potable colors, backflow protection, and an annual cross-connection inspection. Recycled water rates are typically lower than potable rates, encouraging large landscape users to convert.
Cross-connecting recycled lines to drinking water plumbing or removing purple-pipe signage can lead to immediate disconnection, fines, and required system testing.
