Pulling the River Pumps

It took months but we finally got the last job from summer competed.  The wear the pump shafts saw over the last couple seasons required us to remove the pumps and send them away to be refurbished.

The unknown is the cost.  Last time out it cost $10 000 for both.  Until they get the pumps apart and look at the wear the actual cost is hard to say.  Guaranteed it will not be less.  To compliment the maintenance work we completed this fall at the river intake we are looking at ways to mitigate the wear the pumps experience during run off.   One idea is installing a screen sized for the material suspended in the water during run off that is the entire length of the pump (i.e. from the blue pedestal all the way to the bottom bowl).  It's more involved than I'm letting on but the catch with that one is you have to be able to clean it.  Not impossible for us but not that easy either (go here for a reminder?).  The other option is a well but to meet our demands that could cost in the ten's of thousands.  I pretty sure this year will be an exploratory year since grand expenditures aren't really in the cards.
