Figure 1-18. Potable Water Distribution System
Storage Tanks (7). Three 3000 gallon (11,355 I) storage tanks provide temporary water storage. The tanks are of air collar
(onion tank) design.
Distribution Pump (2). This pump provides water for distribution through two hoses with dispensing nozzles. The start-stop
station for this pump is mounted inside the "rear" door of the van (on distribution system side). A local switch at the pump
must be in the ON position before the pump can be turned on. This switch also turns the pump off/on as long as the start
button has been pushed.
Product Shut-Off Valve (3). This valve blocks water loss during cleaning and can be used to provide sufficient back pressure
for the utility hose when filling tanks.
Dispensing Hoses and Nozzles (4). These hoses, with attached nozzles, are pressurized by the distribution pump to deliver
potable water from the storage tanks.
