How many have a foul water drain?

Hi all,

I'm just looking to see how many people have foul water drains at their school, and for those who don't, to know are they collecting up all their waste materials and storing for collection.

We don't have one, but collecting all the waste is proving quite a large task. I've been collecting solutions such as those containing transition metals and evaporating them. But this is only feasible by leaving them on a hot magnetic stirrer with a fan blowing on them. I then add the resulting crystals or concentrated solutions to my waste storage bottles. Am I being mad?

Unless your school has a septic tank system then you will have at least one

foul water drain

see http://www.arca53.dsl.pipex.com/index_files/drain4.htm for info

the term foulwater

includes water from toilet and sink and bath as opposed to surface water which is rain water , the foul is considered that water that needs treatment at an effluent plant before discharge into a water course or the sea whereas rain water is caught and goes directly into a water course

Quite simply th drain that takes sewerage away.

So are you saying it's safe to pour chemicals down the toilet? My lead technician is adamant we don't have any sink or drain that's a foul water one. Possibly because the building wasn't built for science.

I would contact my local water authority to asertain if indeed you don't have a foul water drian in the first instance

I was told when I started that I should dilute any waist before disposing of it in accordance with the CLEAPSS / SSERC guild to its lowest concentration where It was not classed as hazard in most cases this is almost at our working strength or by only disposing of a small quantity per day.

Thanks. In instances where something does go down the sink, I do dilute it and run the tap a while after to be sure. The water authority idea is good. Cheers.
