Rather than let the water from a hot tub drain away, you can use it to water plants in your garden. Hot tub water counts as "gray water," water that is not actually dirty, but has been used for something else. Using gray water reduces household water consumption. Water conservation is not just important in drought stricken areas. The energy required to pump and treat water is considerable. Conserving water reduces energy consumption, which is helpful to the environment and may save you money.
Things You'll Need
- Hosepipe and attachment
- Rainwater barrels
Stop using the hot tub two days before you plan to drain it. Stop adding chemicals and remove the cover. This allows any chlorine, which can be toxic to plants, to dissipate. Alternatively, use mild "green" chemicals in your tub.
Attach a hosepipe to the drain on the tub. Suitable attachments are available from the supplier of the tub, if you don't already have them. Use the water immediately in your garden, or transfer it to rainwater barrels.
Use the water the same day. Gray water should not be stored for long periods of time. The water is safe for flowers, your lawn and trees.
