Working with demand area expected leakage

00:04

In info works.

00:05

WS pro a demand area analysis provides data that allows users to

00:09

review the current demand for water and project future potential demand areas.

00:15

After generating demand areas from area codes with the demand area grid open,

00:20

you can view and edit the parameters of the

00:22

expected leakage calculation and review the results of the calculation

00:26

from the grid right click demand area 35 and select properties.

00:31

The demand area 35 dialog box appears which

00:34

contains the properties for this specific demand area

00:38

to view the results as a graph open the expected leakage tab

00:44

the infrastructure correction factor ICF field displays a factor

00:47

that indicates the relative condition of the mains.

00:51

The expected range is between 0.1 and two where

01:01

The pressure correction factor PCF field displays a factor that is used to correct

01:06

the AZN P or average zone night pressure to a standard 50 m.

01:12

The expected range is between 0.1 and three.

01:16

If a default value is chosen,

01:18

then the value of the PCF will be

01:20

calculated according to the chosen leakage index method.

01:25

The value for A

01:26

and P is taken from live data where available.

01:29

Otherwise the simulation results will be used.

01:33

The leakage index method uses either leakage indices or

01:36

the 1.5 Power Law to calculate the pressure correction factor

01:41

in the table.

01:41

Both background losses and equivalent service pipe bursts are

01:45

calculated using the infrastructure and pressure correction factors.

01:49

The number of props and the length of mains

01:52

reviewing expected leakage calculations allows you to ensure reliable and

01:57

efficient service across all points within a demand area.
