Lovion ASSET WATER Water Plants

Documenting Water Plants and Assets

The Lovion ASSET WATER datamodel for water depicts documented assets within the water grid. These include:

• General stations
• Pressure reducing and enlarging stations
• Measuring shafts
• House connection shafts
• Water collection and transmission stations
• Water production stations
• Water processing plants
• House connections with components
• Central controller for customer's house
• Drinking fountains
• Trickle galleries
• Spring tappings

Structure

The structure is strongly based on valid rules and regulations of the German association for gas and water specialists (DVGW). The georeferenced GIS database is supplemented by logical plant structures supported by the system's hierarchical structures. There is a distinction between the network component i.e. house connections and the customer component i.e. water plants/water production plants. Technical or contractual differences (ownership, third party water collection plants, installation systems, pressure zones, hardness etc.) can be documented individually. House connections can simultaneously serve as the linking element between existing geoinformation systems. The entry point of the isolation valve or the node of the supply line is usually used as the linking point. It is also possible to use the connection between the object for the water connection and the ERP system.

Data Model

The data model is described in more detail in a feature class diagram. All linked feature classes as well as parent and child objects are included in order to visualize the structure of logical connections.
