Sizing of balance tanks for water distribution systems
Sizing of balance tanks for water distribution systems
(OP)
Hi, how would you size the balance tank?
Here's a pump station delivering 40m head and 1000 l/s down a main line 45km long running mostly down hill with beaches off to outlets on both sides.
The pumps are variable speed. Does the system need a balance tank? What are the considerations in sizing a balancing tank?

From the pump station the pipe line diameter will initially be 710, then it will reduce in stages to DN630, DN 560, DN500... etc. after the take-off Tees. Demand will be seasonal for only 6-7 months of the year, the pipeline may be dry after that.
Any input in what are the considerations in sizing a balancing tank would be greatly appreciated.

We will get the system modelled at a later stage, but I don't have access to those engineers right now and I need a cost estimate to get the project over the line.

You may wish to confirm the process requirements for the "balance tank". The term "balance tank" seems to be associated with UK practice.
Sense this is a seasonal application, there is no need for storage, there is no need to maintain a constant system pressure, and the pumping application is very large, any type of balancing tank would not be warranted.
