Turnover and water quality for EST
Turnover and water quality for EST
(OP)
Does anyone know a rule of thumb on a reasonable turnover rate for an elevated storage tank to maintain water quality? Is one day sufficient? Does the entire tank need to empty? Any info would be appreciated. I looked through previous threads and didn't see anything on this. Thanks.

Water temperature- the warmer the water the quicker your disinfectent will disipate and the water quality degrade. If you are in an area where the water stays colder, you may not have to turnover the water as often.
Disinfectant residual- the higher your residual at the tank the longer you can leave it in without having to refresh it, or if you redisinfect at or near the tank, you may not have to turn it over as often.
Water's propensity to form DBPs- If your water and disinfectant combine to form disinfectant by-products readily, you may need to turnover your tank more often.
Because each system is unique, there is no hard and fast rule on how often a tank should turnover.
