I wish you luck finding a commercially available filtration system, suitable for high volume recirculating water like a splash pad, that will reliably remove pathogens.

A properly maintained (good luck!) DE filter might do the trick, but they’re messy enough that they’re banned in large parts of the country. Cartridge filters are usually rated at 10 microns, which is nowhere near good enough.

You don’t filter the pathogens. You filter debris and kill the pathogens with UV, chemicals, etc.

It would not be hard to make a significant improvement by just adding UV sterilization.

> Imagine what we could have had in our communities if we hadn’t wasted $3,000,000,000,000 on Iraq.

What we would've had was $3,000,000,000,000 less debt, and still no splash pad filtration.

The Iraq war was put on the credit card.

We'll never know if we would have had splash pad filtration if the Iraq invasion didn't happen. What we do know is we were lied to by a presidential candidate and many of our solders were either killed or broken and many many Iraqis died because of that lie. Oh, and greed.

I think we can safely say that splash pad filtration and the Iraq War have no relation and we’d be in exactly the same fecal contaminant situation whether or not we invaded.

And boy is HN getting weird.

I was merely responding to the waste of money comments. Context is often lost on some, sadly.

Locally they're required to either not recirculate water or to chlorinate the water a la a pool. Most localities do the former.
