Many home water treatment systems such as point-of-use filters do not consume any water and hence are really not the subject of best use practices and drought actions. The information below pertains only to home water treatment systems that consume water such as reverse osmosis systems and some water softeners.
If you have a water softener or reverse osmosis system that consumes water in the treatment process you have only 2 choices during a drought:
- Leave the system on; or
- Shut the system off.
On most systems you will not be able to reduce the amount of water consumed in the treatment process.
If you opt to leave the system on, make sure that the regeneration and cleaning processes (the water consuming elements of the treatment system) are programmed to occur overnight between 2:00 and 5:00 a.m. when there is very little other water use occurring inside the house.
If you turn the system off there may be complications for starting it back up again. Consult your instruction manual or contact the system dealer if you have any questions about this process.
