Everywhere you go in North Texas people are fascinated by the recent Cryptosporidium outbreak that has already caused more then 100 people to become ill after a trip to their local public pool/lake. Terms like “hyper” and “super” chlorination” are now common place on the evening news.
Sadly it all stems from people who don’t practice good hygiene or parents who don’t watch their kids closely enough. Babies should wear water diapers and kids and adults should use a bathroom not the pool. If people follow those simple rules, no one gets sick.
There is help though. Plano uses a Ultra Violet light filter that is said to be 150 times more powerful then the sun. Needless to say the UV filter kills everything in the water. Plano only uses the UV filter on the indoor pools but is considering installing them on outdoor pools.
The UV filters are expensive, 60-thousand dollars each. Even so, being the germ freak that I am, every pool should have one. If they don’t, you won’t see me in it!

Lewisville also uses a filter that kills Crypo in their spray parks.

The rate at which the pool can be turned over (gallons/hour) is the rate limiting step of UV disinfection. If you have a 60,000 gal pool and the filter only kills at a rate of 1,000-5,000 gal/hr it is at least 12 hours if not days before 60,000 gallons of pool water is treated. Now you need to determine the efficiency of the pool’s flow and how much of the water is NOT being treated per hour?
If the pool is reinfected it all starts over again. Expensive filters can help but are not the solution to fighting the crypto problem!!
