Raising the sewer is actually easy ! In Europe one can find a self contained unit which plugs direct on the drain and with a floating switch activates a pump which is able to lift the sewer 10 m high and pulse it 50 m long... the exhaust tube is 32 mm dia, so it is easy to route, and cheap...
In my camera club, at its previous location we had a huge sing made of plywood reinforced with fiber glass tissue glued with epoxy resin. This sink resisted 40 yes, 40 years of common use and abuse by the children one afternoon every week (kids above 10 and under 17) So I plan to make mine using the same technique ;-) it will survive me, I think !
My only difficult problem is piercing the basement wall for a plastic tube of 100 mm to route the fresh air. (I forgot to ask the contractor, which has made one hole, for exhaust, but did not know I needed to let air in, also...)
Anyway, I'm impressed by the innovation people place in their darkroom !
Thanks for your help !
