A system for transport and delivery of an antifreeze solution may include a first tank configured to contain the liquid, the first tank including a first tank outlet line and a first return line. A system may include a delivery system flow connected to the first tank, the delivery system including: a pump configurable to draw the liquid through a pump inlet line in flow communication with the first tank, the pump inlet line selectively connected to the first tank outlet line, and a manifold connected to the pump, the manifold selectively configurable to direct the liquid to one of a system outlet line and the first return line for returning liquid to the first tank. A system may include a transfer tank configurable for sampling the liquid and including a transfer tank outlet line configurable for transferring the liquid to the delivery system.
