Water is purified one drop at a time by reverse osmosis devices. A reverse osmosis holding tank guarantees that you have access to this water whenever you need it, rather than having to wait for the system to carefully fill your drink. Many wells are low-pressure and low-recovery, and they are charged with supplying pressurised water to a home or company. When you switch on your shower or empty your toilet, a well pressure tank guarantees that you have instant access to pressurised water. They also serve to prolong the life of the well pump by preventing short-cycling.   

A water storage tank holds clean water from your reverse osmosis system until a demand for water is initiated in the house or business. Water is pumped into the tank from the water source, like a well or a reverse osmosis system. The tank accumulates water until it is full. When you need access to water, be it to fill your glass up with crystal clear water, run a bath, or irrigate a field, the storage tank provides you with instantaneous access to water.
