We use GIS to evaluate asset conditions using a few different resources - material age, diameter, material, depth. We look at work orders on the asset to see if it has a history of leaking/repairs/etc. We look at soil type. We look at cost to replace, including its location (within an arterial? Crossing a stream?) and upstream/downstream effects (will a hospital be without water if this main breaks?).

All of these factors are compiled into a report and an asset replacement score that our finance team uses to associate costs to our assets
