There’s a great deal of attention on water conservation and smart water use, especially in areas of the country where rain or snowfall are below normal levels.

Here are some tips to using your old spa water wisely.

The water in your hot tub can be recycled for use around your home, decreasing the amount of fresh water you need.

Here are answers to some common questions when it comes to recycling spa water:

Is Recycled Hot Tub Water Considered the Same As Water from a Tap?

No. Spa water is classified as “gray water,” similar to water from baths, showers and bathroom sinks.

Using gray water serves two purposes:

1. It can the reduce amount of fresh water needed for some household tasks.
2. It lessens the amount of water entering the waste treatment system.

Can Water From All Hot Tubs Be Recycled?

Some hot tub brands use salt water systems that may damage lawns or shrubs, so it’s not recommended for use on plants.

Does the Water Need to Be Treated in Any Way Before It’s Used?

Most sources recommend waiting for three days after chemicals were last added to your hot tub, turning off the spa and allowing the water to cool. Chlorine should dissipate quickly, especially if you leave the cover off. After three days, test the water to make sure that the chlorine level is at zero. The pH should be between 7 and 8 to be safe for plants.

How Do I Get The Water From My Hot Tub To Where It’s Needed?

Most portable hot tubs drain by gravity from a valve at the bottom of the spa that can connect to a garden hose. Using the hose, you can apply the water where it’s needed. However, it only works if you’re level with the hot tub or downhill from it. You can always collect water to be recycled in buckets that are easily moved to areas of use.

You can also purchase an inexpensive submersible pump for $50 to $100 (make sure it connects to a garden hose where the water comes out or has an adapter). With it, you can pump water into storage barrels or apply it directly to the task at hand.

What Are Some of the Best Uses for Recycled Hot Tub Water?

Recycled hot tub water can be used in a variety of creative ways, such as…

• Water the lawn, shrubs, ornamentals, flowers and trees. It’s best to use it on well-established plants. Do not use it on edible plants.
• Wash your car.
• Wash your patio furniture, grill, lawn mower and other outdoor equipment.
• Wash out your garbage cans.
• Rinse down the patio and driveway.
• Use it to flush toilets, pouring it directly into the bowl rather than the tank.
• Store it for later use in barrels or clean trash cans.

Is It Safe to Use Recycled Spa Water on Vegetables and Other Edible Plants?

We do not recommend using your old spa water on your vegetable garden.

Are There Restrictions Governing How I Recycle Water?

Potentially, yes. All recycled water uses are ultimately governed by local jurisdictions, and those take precedence over any of the above suggestions.

After using your spa’s water for months to treat tired muscles, relieve pain and help you rejuvenate, you can potentially get even more use from that water. And that makes your hot tub one the most efficient water users in your home.

WHAT DO YOU THINK?

As we learn more and more about water conservation efforts, we’d like to hear how you’re taking action. Are you already conserving or recycling water in your home? Would you make the effort to use recycled hot tub water for decorative plants that aren’t getting enough moisture?

We’re also very interested in what other uses you can think of for your recycled spa water. Please leave us a comment so others can take advantage of your ideas. Thank you!
