Hello all,

Here in Bangor  we’ve had our stormwater infrastructure in GIS for some time, but currently use a grid-based numbering system which is not particularly useful for anyone.  We’re considering a switch, as we have not done a significant amount of asset management on stormwater yet and the current system is quite confusing for our field crews.  Looking ahead, toward more asset management work, we’d like to have a better system in place. 

  

Our sanitary sewer system is numbered like a branching tree, with a two letter prefix denoting subsection and a three number pipe id number, which are divided into branches by 100s / 10s as necessary.  So for instance AB123.  This system works well for us, but unfortunately can’t easily be replicated for our stormwater system because it is discontiguous in nature. 

 

Our current grid-based system is more-or-less arbitrary, but includes the complication of using a grid which is otherwise unreferenced elsewhere in the city.  This is creating many headaches and conflicts among staff.

Would you be willing to share what your community is using for stormwater numbering and what the pros and cons have been in using this numbering system?

Thank you very much,

Sean
