Alternate water sources central to green code

摘要

DOWNERS GROVE, ILL. -The topic of alternate water sources was a significant focus of the Green Technical Committee of the International Association of Plumbing & Mechanical Officials. The GTC met here in late August as it refines the latest edition of its Green Plumbing & Mechanical Code Supplement (GPMS). Non-potable water received considerable attention. Inside buildings, the GPMS requires bathrooms to have signs stating that they are using alternate water sources. The sign must state that the building uses "X" to flush toilets and urinals, with whatever "X" is being the source of the water source, such as municipal reclaimed water or rainwater. To protect the contractor or service tech, the mechanical room has to contain signage stating which equipment contains non-potable water.
