You can make an estimate for the cost of water in your water supply system
00:07
by including a unit price for water transfer through any pipe control.
00:12
You can apply a different unit price to flow in the usual direction (From Node to Node)
00:17
and the opposite direction (To Node to From Node).
00:21
To allow you to apply prices to both import and export, or the bulk sale of water,
00:27
negative unit prices are allowed.
00:29
As an aid to reporting, the cost at a particular pipe can be given a category.
00:35
There are built-in categories to choose from, and you can add your own categories, if needed.
00:41
A common use of this facility would be to calculate the cost of water imported to or exported from the water supply system.
00:49
You would apply a positive price on links attached to transfer nodes for all imported water,
00:55
and a negative price on the same links for flow out of the system.
00:59
You can also come up with a comprehensive estimate of the total cost of water in the system, by applying a cost to all links.
01:07
For pumps, this cost will represent costs in addition to the electricity cost calculated from the Electricity Tariff.
01:14
You can then add the Price of Water figures to the electricity costs to get a total cost estimate.
01:20
For each link, you can include the cost of water in each direction to a category.
01:25
For example, you may include the price of water in the From Node - To Node direction in the Export category.
01:31
The available categories are: Treatment - total cost of water treatment,
01:37
which may include filtration or chemical treatment
01:39
Chemical Treatment - total cost of chemical water treatment
01:43
Chlorination - cost of chlorine injection and dosing
01:48
Import - cost of bulk water imported to the network
01:52
Export - cost of bulk water exported out of the network (this cost would be negative)
01:59
Transport - transport costs or revenue for water transfer
02:04
Extraction - cost of well or borehole extraction
02:08
Pumping - any costs other than electricity costs from the electricity tariff.
02:14
For example, maintenance or depreciation costs
02:17
Other - user defined
02:21
To calculate the price of water in a simulation, a cost associated with the movement of water within at least one pipe
02:27
needs to be included.
02:29
Begin by opening the PoW Network and Control by double-clicking on the PoW Network in the Model Group.
02:37
Expand the Stored Query Group and then double-click the provided PoW stored query to open it.
02:44
You will see a query already populated, which assumes that the unit cost of forward and reverse transport is £2/kL.
02:52
Before running the query, click Test to make sure it is valid.
02:57
Then, click Run.
02:59
The PoW value in the Pipe Control should now be updated.
03:03
Open the properties of any pipe, then check that the PoW Unit Cost under Pipe Control has been updated.
03:11
You can also check this by using the New Links Window.
03:15
Commit the changes to the Control.
03:18
Right-click the Run Group and select New > Run.
03:24
The Schedule Hydraulic Run dialog opens.
03:28
Type a name for the run.
03:30
In this example, “PoW” is entered.
03:33
Check the box next to Experimental.
03:36
Then, in the Model Group window, click and drag the PoW network into the Network group box in the dialog to populate the Network,
03:44
Control, and Demand Diagram fields.
03:47
Click Save, and then Run.
03:50
When the simulation is complete, double click the PoW Control simulation to open it.
03:55
Then, expand the Grid Windows tool and choose Link Results.
04:01
In the Link Results table, you will see a column for the Forward and Reverse cost of water for each pipe.
04:07
You can export or copy this table to Excel or a similar program to further manipulate the data.

The PoW value in the Pipe Control should now be updated.
The Link Results table reports the Forward and Reverse cost of water for each pipe:
