Rod Gurganus, director of North Carolina MarketReady, and Gary Roberson, a North Carolina Cooperative Extension specialist in biological and agricultural engineering, designed the original prototype in 2008, according to a news release.
The model was intended for commercial use in farm fields.
But grower feedback during field tests in 2010 suggested the two develop a smaller unit that could be more cost-effective and practical to use at farmers markets.
“Food safety starts on the farm, so it’s essential that our growers have access to adequate, affordable hand-washing facilities for use in the field and at direct points of sale, like farmers markets,” Gurganus said in the release.
With a $24,000 grant from the North Carolina Rural Economic Development Center, the two designed a unit that costs about $2,000 to build, depending on materials and customization.
The cost of the wagon or support trailer was not included in that cost figure.
