a number of Roe/Rowe entries in the index listings from the above directories, but none mention mineral water, and none are on Blessington St
The only Roe listing even remotely drink related occupation is a George Roe & Co. Distillers in 1863, 1872 at various address including Thomas St & Mount Brown. Not everyone is shown in the index or trades index, but you need a specific address to double check on the street listing.
there's a number of Mineral water manufacturers listed - but no Roe/Rowe - e.g. here's the 1868 listing
Mineral, Soda Water, and Ginger Beer Manufacturers.

dont worry about the spelling variation between Roe, Rowe etc, this is quite common with many names. The spelling of names was not standardized and the way a name was spelt could depend on the individual creating the record.
