Within any asset management system there is a need to have assets effectively categorised. In typical water and sewer networks they have been traditionally catergorised under the  product they are transporting. As recycled water and stormwater systems are introduced to the networks there is a need to clearly identify those categories and how best they are to be applied to the operational activity.

There are of course health and safety issues related to all these components and perhaps some long term  and more broadening of the types of asset categories is appropriate for improved asset management.
