Safety of drinking water.
I'm planning a trip to the Big Island in Hawaii, and the vacation house I'd like to stay in uses treated rain water. Here's what they say about it:
"As for the water. We do collect our water via rain in our 10,000 gallon catchment tank. If rain is short we have water delivery. We treat the inside water through a double filtration system, then sterilize it with UV light prior to entry into the house. We have our housekeeper treat the water in the tank with chlorine and baking soda to steady the PH level."
Is this likely to be safe to drink, cook with, brush teeth with, etc.?
Outside United States drinking water
Yes. That is an acceptable treatment system. The water treatment with the UV light disinfected has a step beyond most city and community systems.
Thank you for your input. It was very helpful.
