The Twitter post "waterway 0 singapore" does not relate to a maintenance report feedback to public flat house. It is not a specific location or facility related to public housing, and does not mention any issues or requests for maintenance. Therefore, the answer is "relatedness": False, "type": "none", and "explanation": "This is not related to public housing or maintenance."
