Pure speculation here but anyway.
I have some (very little actually) knowledge of environment impacts, sewage treatment, water treatment, septic fields, etc. - It's been over 25 years since I did any work of that sort and the state of the art has changed, however I do sort of keep up a bit.
1. DCL and Castaway Cay are monitored by a variety of watchdog agencies. If Disney was pumping raw sewage into low areas on Cataway Cay, there would be plenty of people who noticed, and plenty of fines and bad PR.
2_ Disney has a desalinization and sewage treatment plant on the island. You can google that and read about it all over the internet from various sources.
3. There are treatment methods where effluent is pumped to open holding tanks where solids are left to settle. There are also aerobic methods where oxygen is bubbled up through open tanks where wast water is held before moving on to subsequent additional treatment.
4. You can also separate grey water (from laundry, or the kitchen) from black water (human waste) and treat them separately. Grey water impoundment is an option. Greywater can also be used for irrigation.
So it is very possible that this person who worked at Castaway Cay did see waste water being held, or pumped to open areas. It is also very possible that this was still an environmental sound method that he witnessed.
Everyone who has lived near a #%(* plant knows about those settlement tanks. (or even near certain farming operations.. I'd take a human sewage plant over a pig sewage settlement pond.. hands down, any day of the week).
