Talked with Janne last night and he has received the water pump and associated fittings; it was part of a larger order he placed for a bunch of work he's doing. He will get it installed next week. The electricity isn't there just yet, but the paperwork has been processed so it should be a matter of days. Janne is confident of having everything in place by June 1 as planned.
And, right on cue, I just got an email from Willie, who says it's snowing up where he is! He's proposing week 28 (July 7) to do the foundations. He's going to call Janne tomorrow to sort out logistical details. I'm also going to ask Stefan to send along any further construction drawings.
