The rule that matters most here
After a Cryptosporidium notification, the Guidelines (§9.2) require hyperchlorination — 20 mg/L for 13 hours or 10 mg/L for 26 hours — unless a validated secondary disinfection system such as UV is installed. For a swim school that is the difference between a closed day and a normal one.
What a small plant room needs
- A validated UV unit sized for the pool's actual flow — small pools do not need large chambers.
- A controller that measures free chlorine and pH, with an output so readings go to a log.
- A daily DPD check written against the controller reading.
How we work with chains
One review at one site, one configuration agreed, then repeated across the other sites with the same log. Equipment is supplied through your pool contractor.
