I have a request regards time to half empty of infiltration systems.
Irrespective of what I set in the preference page (whether time to half empty by volume or by storm) I just get time to half empty of the structure.
That isn’t very useful information.
I spent a bit of time today (too much really) running various storms and adjusting the depth of a soakaway for each one so as to get the time to half empty for each individual storm (much more useful information) and produced the table replicated below:
Storm |
Depth of water |
Half drain time |
|
1:10 year |
1.165m |
1,558 minutes |
(26 hours) |
1:30 year |
1.623m |
1,910 minutes |
(32 hours) |
1:30 +35% |
2.282m |
2,289 minutes |
(38 hours) |
1:100 year |
2.359m |
2,326 minutes |
(39 hours) |
1:100 +45% |
2.724m |
2,662 minutes |
(44 hours) |
This would be an excellent addition to Flow.
The time to half empty based on the depth of water for each storm in a soakaway.
(and would save an awful lot of time messing around with multiple models)
Is this something that can be added to the flow wishlist?
