You can base the water-use data for bnetley lump-sum areas on system meter data from pump stations, treatment plants or flow control valves, meter routes, pressure zones and TAZ traffic analysis zones.

Where can I find a manual (user guide)?

Assigning metered demands to nodes is a point-to-point demand allocation technique, meaning that known point demands customer meters are assigned to network demand points demand nodes. Assigning metered demands to pipes also is a point-to-point assignment technique, because you still must assign demands to node elements, but an additional step is involved.

Piping routes are not considered, so the nearest demand isn’t necessarily the location from which the meter actually receives its flow.

Discover the exceptional performance of DxO Optics Pro. The demands associated with the meters within each of the service area polygons is assigned to the respective demand node points.

Due to the difficulties associated with manually loading the model, you can use automated techniques developed to assist with this task. This strategy primarily is a manual operation and is used to assign large generally industrial or commercial water users to the demand node that serves the consumer in question.


These techniques are similar to the flow distribution allocation methods, except that the type of base feature class that is used to intersect with the service feature class may contain information other than flow; for example, land use or population. Follow Lynn on Twitter. In figure 3, the total demand in meter route A may be 55 gpm 3.

Service polygons define the service area for each of the demand nodes. If the data relates to projected values, you can use it for demand projections.

The spatial analysis capabilities of GIS make these applications a logical tool for the automation of the demand allocation process. The conversion required will depend on the watergesm data used.

When using the nearest pipe meter assignment strategy, the demands at a meter are wtergems to the nearest pipe. Depending on how the feature classes intersect, service areas may contain multiple demand types land uses that are added and applied to watergemw demand node for that service polygon. The geographic location of the meter in the GIS is not necessarily the point from which water is taken from the system, but it may be the centroid of the land parcel, the centroid of building footprint or a point along the frontage of the building.

The known flow within the lump-sum area generally is divided among the service polygons within the area using one of two techniques — equal distribution or proportional distribution: The total flow is then equally divided among the demand nodes within each of the meter route polygons. Estimation of Demands Using Land Use and Population Data Automated techniques also can assist in the estimation of demands using land use and population density data.


Check out our Forum Guide for the instructions all forum members agree to abide. Billing Meter Aggregation Billing meter aggregation is the technique of assigning all meters within a service polygon to a specified demand node.

In her easy-to-follow, friendly style, long-time Cadalyst contributing editor Lynn Allen guides you through a new feature or time-saving trick in every episode of her popular AutoCAD Video Tips.

Note that you can use these data sources to assign current demands; the difference between the two being the data that is contained within the source. This conversion entails translating the data contained within your data source to flow, which you then can apply using LoadBuilder.

Deep Excavation A Practical Manual. You can use this type of demand estimation in the projection of future demands; in this case, the demand allocation relies on a polygon feature class that contains data regarding expected future conditions.

Actify SpinFire Professional v8. Infonet only can import xml files from Wincan V8. The equal flow distribution option simply divides the known flow evenly between the demand nodes.
