The evil that is in the world almost always comes of ignorance, and good intentions may do as much harm as malevolence if they lack understanding. Albert Camus Average cost of hauling 7,500 gallons is approx. $225.00, or $.03/gal Average cost of a tank wagon delivery 4,500 gallons is approx. $225.00, or $.05/gal (but usually greater) Why – almost the same amount of drive time, fuel usage, and driver labor. Cost of equipment is similar, but there is a much smaller market for specialized tank wagons. A class 8 tractor and trailer can be used in a wide variety of applications. Assuming one load per week, the additional cost of smaller loads is $7,800/ year.

12,000 Easier to forecast if usage is erratic 5.2 hrs to call and receive product Less potential to overfill Less potential for dead-head/high pressure equipment failure The evil that is in the world almost always comes of ignorance, and good intentions may do as much harm as malevolence if they lack understanding. Albert Camus 10,000 Easier to forecast if usage is less than 1300 gal/day or spread out evenly. 2.2 hrs to call and receive product higher potential for overfill condition greater potential for dead-head/high pressure equipment failure

Albert Camus 2 – 6000 gal tanks 5.2 hrs to call and receive product Higher potential for overfill condition due to ullage calculation of multiple tanks (true but hard to believe) Greater potential for dead-head/high pressure equipment failure because one tank has to be filled, product stopped, and balance placed into other tank Twice and many connections/hook-ups performed and reading taken. This is where a majority of spills occur. Higher cost – two 6,000 gallon DW tanks are substantially more than a single 12,000 gallon DW tank. Piping, overfill protection, vents, valves and fittings are double. Concrete footprint is larger.
