A mobile pump and hose assembly deployment, decontamination, storage, and transport system (DDST) (10) having a support frame assembly (14) supporting two boom assemblies (16) and a take up reel assembly (18). Each boom assembly (16) is segmented, hinged structure that collapses from a deploy position to a compact store position and includes a primary reel (20) for storing and deploying a pump (144), and pump-to-hose adapter (144), and a pump hose (138) into a well (149). A plumbing tree (126) is situated within each primary reel (20) and provides a fluid and electrical connection to the pump (144). The take up reel assembly (18) is adapted to receive the pump (144), pump-to-hose adapter (143), and rotates to receive the pump hose (138). As the pump hose (138) is wound onto the take up reel assembly (18) from the primary reel (20) is can be passed through an external hose cleaning apparatus (194). The take up reel assembly (18) is a pivotal structure, allowing the pump (144) and pump-to-hose adapter (143) to be positioned in a cleaning portion (166). A recirculation cleaning loop can be formed by first filling the cleaning portion (166) with cleaning fluid (234) and connecting a recirculation hose (232) between the plumbing tree (126) and the cleaning portion (166). The cleaning fluid (234) is pumped by the pump (144) through the pump-to-hose adapter (143), the pump hose (138), the plumbing tree (126), the recirculation hose (232) and back into the cleaning portion (166). A containment sink (22) is disposed beneath the take up reel assembly (18) to collect cleaning fluid. The entire system (10) is covered by an enclosure assembly (24) to prevent contamination during transport, and unauthorized use.
