No, this term is not about the distribution of swimming pools (though that definitely is possible). This term is defined as the regular distribution of orders to multiple destinations within a certain geographic region. Usually, they will be regular LTL shipments. From the original warehouse/manufacturer, goods are shipped to regional centers to be shipped out regularly to smaller local cities and clients. Instead of making multiple long-haul trips from Oregon to New Hampshire, a company can have a regional pool distribution center in Connecticut for the entire NE seaboard. Pool distribution is a great and cost saving way to make smaller shipments regularly to many clients.
