Enclosed please find the completed and signed renewal application and supporting
documentation for the above referenced permit number. No changes have been made
since the previously submitted application in 2015.
The reverse osmosis system at the Garden's Orchid Conservatory functions to purify
the water supply for hand irrigation and a high pressure fog system that maintains
proper humidity in the greenhouse. Well water supplies the purification system and
wastewater is delivered to a nearby unnamed tributary of Catawba Creek via
underground storm drainage.
