	Water Balance Diagram
	Water Balance Series
	Water Balance Bar Chart (this page)

Overview

In this page the user can compare the different water balance components between different zones, in terms of volume (absolute value or percentage) or cost (monetary units or percentage).

The water balance components are calculated as explained in the Water Balance Diagram page.

The costs are calculated for the real and the apparent losses. The real losses cost is obtained by multiplying the volume of real losses by the average water production cost (that should include all operational costs) whereas the apparent losses cost are obtained by multiplying the apparent losses volume by the average water tariff. These average costs variables are entered by the user at the Administration level, in the Settings Configuration page. 

This page is particularly useful to identify the volume and costs associated with real and apparent losses for each zone, support the definition of priority zones for intervention and the best actions to implement.

Graph by volume or cost

The Water Balance Bar chart let's the user select between graphing "Volume" or "Cost". The upper graph allows the user to compare absolute values between different zones, while the lower graph allows to compare relative values between different zones. Comparing the two graphs simultaneously is particularly useful as bigger zones tend to have bigger volumes or bigger costs associated, however they may represent a lower value when comparing with the total system input volume or the total cost of each zone (relative percentage). The prioritization of zones for intervention is usually done by looking at both absolute and relative components. 

Note: the user can select which components to view in the graph by selecting the respective component in the legend, below the graph.

Zones 

List of configured Zones. Select the ones to include in the bar chart.

Most utilities manage their systems based on bigger zones (usually called operational zones or distribution systems), being each operational zone or system composed by several smaller zones (usually called DMA). In WaterSight it is possible to consider these two levels of zones hierarchy, but it is also possible to consider three or more levels of hierarchy (for example a town, that is composed by several distribution systems, being each system composed by several DMA). More information  in the zone configuration help page.

Months 

List of months for volume/cost aggregation.
