Ehud et al.
We only resolved this in the former Environmental Archaeology Unit here by
having a sump/settling tank constructed outside the building in which the
sieving apparatus was housed. The sediment collecting in the plumbed-in
sieving machine could be flushed into this via a large-bore pipe every so
often. Of course this requires not only the space (and funds) to sink the
tank and piping, but also needs the periodic visit of a firm who specialise
in disposal of waste of this kind - they come with a tanker and suck out
the sediment!
Prior to that we relied on settling tanks underneath the sinks we used for
sieving (which was on a much smaller scale) - the English vernacular word
'palaver' is the best description for what was involved in uncoupling all
the pipework and removing the tanks for disposal of the sediment on some
waste ground several hundred metres away across the campus... and at that
point we were working on the top floor on a four-storey building with an
erratic elevator! Happy days...
