Hello,
You have raised a similar query recently
I understand the frustration of having rejections and sometimes we need to let that frustration out but can I remind you to be respectful to your fellow wayfinders.
You can write in your own language to help prevent misunderstandings.
In that previous topic the community tried to explain and assist. In particular they explained the situation around hospitals.
A water tower is a basic utility to help ensure a good supply of water. They are often distinctive structures, but it is unusual that they actually meet criteria for eligibility and acceptance.
If a water tower is to be accepted a specific good case will need to be made.
In reviewing your nomination it would appear that several reviewers selected to reject under the question permanent and distinct. This is a confusing combination, and it causes multiple problems especially to the nominators like yourself who receive a rejection reason that is not clear.
They will have ticked this box because as it is a utility item it is not designed to be a distinctive architectural feature but a functional object. They are not commenting on the permanence.
I totally agree this is a confusing message for you to receive as a rejection reason, but I hope you now understand why.
Please take on board the advice that was previously given and ask here first before submission so that we can help you create and draft something that is more likely to succeed.
