A system for delivering a fluid to a fluid consuming asset having a fluid tank is disclosed. An inlet of a manifold is fluidically coupled to a storage tank that contains the fluid to be delivered. A first distal end of a fluid transporting mechanism is fluidically coupled to an outlet of the manifold. A second distal end of the fluid transporting mechanism is fluidically coupled to the fluid tank. A primary valve is fluidically coupled to the fluid transporting mechanism and restricts fluid flow to the fluid tank when fluid level in the fluid tank reaches a first fluid level threshold. A secondary valve is fluidically coupled to the fluid transporting mechanism and restricts fluid flow to the fluid tank when fluid level in the fluid tank reaches a second fluid level threshold. The first fluid level threshold is lower than the second fluid level threshold.
