And I will not bid on it because you are there and I am in Alaska. While I might have some ideas as to what could be done, I do not know the water there and what works best and what does not really work.
As for Valve choices,,, 2510 or the Clack as both can be programed for different time frames of the cleaning cycle.
Autotrol and 5600 can not be.
With any valve choice I would not have the Vortech Distributor, I just could not trust it yet.
