It seems that the Twitter post does not relate to a maintenance report feedback for a public flat house. The post is about the clarity of water in a morning walk in Singapore, and does not mention any issues or concerns related to maintenance or infrastructure. Therefore, the answer is "False" for the "relatedness" field, and "none" for the "type" field, along with a brief explanation.
