On tap.

Mr Smith reads that "MSPs will be asked to swap bottled water for more environmentally friendly tap water. Last year, the Scottish Government provided 123,884 litres of water at a cost of £34,201.90 at its offices in Victoria Quay. The Scottish Parliament also has free bottles of water in the debating chamber and committee rooms for MSPs."

That's a lot of plastic bottles ... even if they are being recycled. And rather ironic given the campaign over most of the last Scottish Parliament's last session to impose a levy on plastic bags by MSP Mike Pringle.
