I am currently in the pre-planning stages of creating a compiled map of wastewater treatment plant assets. I have an idea of what needs to be on it. I would like to see what others have done to capture wastewater treatment plants. I want to see what I can add or improve.
You should consider asking this question in the Water Utilities industry forum instead. You should also consider attending the monthly water utility network users group where you can connect with your peers about water/wastewater/stormwater questions like this.
