Silly question here... Weve gotten so much rain lately that my pool is overflowing! Can I pump the excess water into one of my cisterns for use (cisterns still have a way to go to fill up). No crazy chemicles in the pool just a low level of chorine. Our cistern water goes through two carbon filters and then UV before it hits the tap.
Thanks!

Check a little deeper into the content of the pool water.

PH, Calcium Hardness, Stabilizers and others that can accumulate over time in the pool can be very hard to remediate once in the Cistern.

If it's me "I'm not doing it"!

I would first have your pool water tested by a certified water testing lab for potability.

Wow, wish our pool was overflowing, that's a good thing.
Our pool water evaporates so quickly. I say leave as much water in there as you can.

If you have a garden and are in a relatively dry area, you can store it in a container (Home Depot carries them in various sizes - they have spigot outlets on the side for hose attachment)) and use the water for your plantings.

With chlorine in the water?

Were just coming out of a mini drought on St. John but we've been getting slammed with rain on a daily basis for 2 weeks now (good thing) - that's why we're overflowing but the cisterns have a way to go to fill up.

I left the high water in for a week but it's above the skimmer line so now the pool is getting dirty from leaves and flowers that aren't getting skimmed out.

Grey water tank is full and the ground is pretty much wet from all the rain so it's already pumping down over our hill 🙁 I was thinking if I just pumped the top off the pool that would of been mostly all rainwater before the pool pump turned on a circulated it. Oh well 🙂

If you're just lowering the pool a little, send it over the side. If you are emptying the entire pool for maintenance, then I'd put the water in a cistern temporarily. I would not put pool water into a cistern for use as potable water. You could put it in gray water for irrigation if the chlorine will either evaporate because it's vented, or if it will be diluted enough by other water already in there.

Yes. It dissipates quickly. Diverted my (bleach and detergent) washing machine water for years to a holding tank and saved it for watering in dry spells with never a problem and flourishing plants and veggies of all kinds.

Sorry to be the contrarian...I always pump my excess pool water into my cistern after heavy rains. I put bleach into my cistern regularly and have beautiful clear water that tests perfect. We don't drink our cistern water, but use it for everything else. Never had an issue.

We tested our tap water in Baltimore one time with our pool test kit and found that the chlorine level was at the correct level for a pool! They add Chlorine and Fluoride to the "city" water. So the Chlorine from the pool shouldn't hurt the plants.

When I was preparing to re-grout our pool the year before last I pumped about 5000 gallons of pool water into one of our cisterns, which already had about 5000 or 6000 gallons of rainwater in it. Even though I have a UV system with sediment and charcoal filters, I could immediately taste a significant (unpleasant) difference in our tap water. After a week or so the taste never improved so I swapped to our other cistern because of the taste. So, if you drink your cistern water I would definitely recommend against adding large amounts of pool water to your cistern. But if you don't drink it then your toilets and plants will never know the difference. Another issue that you might consider is that the chlorine stabilizer used in swimming pool chlorine tablets is considered to be carcinogenic by some groups - I was not concerned about it but it is something to take into account.
