Discover the exceptional performance of DxO Optics Pro. From the pipe, the demand then is distributed to the nodes at the ends of the pipe by using a distribution strategy. LoadBuilder facilitates the tasks of demand allocation and projection.

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. Distribution This strategy involves distributing lump-sum area water-use data among a number of service polygons service areas and, by extension, their associated demand nodes. Allocation Allocation uses the spatial analysis watrrgems of GIS to assign geocoded possessing coordinate data based on physical location, such as an x,y coordinate customer meters to the nearest demand node or pipe.
Andres Gutierrez Automated techniques help you meet current demands and plan for the future. Please send any technical comments or questions to our webmaster. 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.
Where can I find a manual (user guide)?
Ideally, you should place these meter points at the location of the tap, but you may only know the centroid of the building or land parcel for a customer account.
Billing Meter Aggregation Billing meter aggregation is the technique of assigning all meters within a service polygon to a watergms demand node. Follow Lynn on Twitter. The following are descriptions of the types of allocation strategies that you can apply using LoadBuilder.
Every step of the mnaual process is enhanced from the initial gathering and analysis of data from disparate sources and formats to the employment of various allocation strategies. Service polygons define the service area for each of the demand nodes. The proportional distribution option by waterfems or by population divides the lump-sum flow among the service polygons based upon one of two attributes of the service polygons — the area or the population.
When using the nearest pipe meter assignment strategy, the demands at a meter are assigned to the nearest pipe. The lump-sum area is a polygon for which the total lump-sum water use of all of the service areas and their demand nodes within it is known metered but the distribution of the total water use among the individual nodes is not.
Automated construction of the service polygons may not produce the desired results, so you may need to adjust the polygon boundaries manually, especially bentlley the edges manuwl the drawing.
The known flow within the lump-sum area generally is divided among the service polygons within the area manuap one of two techniques — equal distribution or proportional distribution: Point Demand Assignment A point demand manusl technique is used to assign a demand directly to a demand node. You can use various data types with this technique, including future land use, projected population or demand density in polygon form with the polygons based upon traffic analysis zones, census tracts, planning districts or other classifications.
Write the CSS code manually or let the style sheet editor do it for you! Service polygons define the service area for each of the demand nodes figure 2. After an appropriate conversion method is in place, the service feature class containing the service areas and demand nodes is overlaid with the future condition polygon feature class.
In most of civil engineering watergesm from Housing to hydraulic related projects hydrology is mostly involved in combination with fluid mechanics. The lump-sum area for which a flow is known must be a GIS polygon. For each of these meter route polygons, the total flow is known. All exclusively from Cadalyst! You can use this type of demand estimation in the projection of future demands; in this case, the demand allocation relies on a manula feature class that contains data regarding expected future watergem.
Meter aggregation is a polygon-to-point allocation technique because the service areas are contained in a GIS polygon feature class, and the demand nodes are contained in a point feature class.

Productivity Corner: Using Bentley WaterGEMS with GIS Data for Water Demand Allocation
This technique is unnecessary if all demands are warergems for using one of the other allocation strategies. Many of these data types do not include demand information, so further data conversion is required to translate the information contained in the future condition polygons into projected demand values.
Due to the difficulties associated with manually loading the model, you can use automated techniques developed to assist with this task. You may need to translate the data contained within the source — such as population, land area, etc. Check out watergemms Forum Guide for the instructions all forum members agree to abide.
In addition, you may not know the actual location of the service meter.
