My question was: I’m looking for sources of 550 gallon black poly water tanks in Vermont.
I only had one response, from Brad Lawes of Lawes agricultural services in Brandon VT, who I use and recommend for a great source of lime, fertilizer and cover crop seeds, among the many services they offer.  So he referred me to Central equipment of CNY, 315 7765300 www.centralequipmentLLC.com
They actually stock poly tanks of every size up into the many thousands of gallons! And they had in stock Black poly tanks, which they delivered 24 hours after I placed my order!  That’s insane and and the prices were better then any other quote I received from my on line searches, mainly due to trucking costs. So, if your looking for water storage for irrigation or any other reason, check them out!
