We are looking for two water coolers - one for the staffroom (currently 15 members of staff rising to 20+ over next few years ) and one for use in our KS1 area (currently 45 pupils rising to 60+ ).
A mains unit would be suitable for the staffroom - but as we have no 'drinking water' outlet in the KS1 area we assume the cost would be prohibitive to get one plumbed in.
