Good Morning Marc,
Any time you store water, you risk the possibility of contamination. If the
system is totally sealed, and there will never be a possibility of flushing
"untreated" water into the tank, you may be o.k.
The least expensive "cure" would be to have a recycle route on the tank where
the clean water can be run back throught the system if it does become
contaminated. Circulating water stays cleaner than stagnant water. UV will
not work since the light will not penetrate very far into the water of a large
tank. Ozone bubbled into the tank would be the best option. This can be
expensive and dangerous (high electricity) but will keep the tank and the
distribution lines relatively free of bacterial contamination.
