About transfer nodes

A transfer node is a point at which a known quantity of water is either put in the water supply system or taken out. This can be done, for instance, through a time-controlled valve, or by means of a booster pump.

The exact date and time can be specified for any transfer, making this system very accurate and flexible. Demand cannot be attached to these nodes.

This option is a little bit artificial. In reality, the transfers are effected by the use of valves, pumping stations or even more complicated facilities. The user can, of course, model all this through InfoWorks WS Pro. However, during the early stages, building the model from scraps of information, the user may find this option easier to get some useful results more quickly. In some cases transfer nodes may remain in the model permanently - to describe trade-offs between different pressure zones, for instance.

You enter the transfer schedule - the date and time for each change in the transfer volume. The volume can be positive or negative - to represent a flow into or out of the network respectively. No interpolation is carried out on the data, so if one transfer flow is given for the start of the simulation, then the flow in, or out, at that node will stay constant over the duration of the simulation.
