Smelly Cistern Water?
Tenants just called today and said the cistern water is starting to smell bad. Is this normal after we have heavy rains and what could it be? I am stateside for the Summer and would love to hear any insight.
ours started smelling too, especially after all the rain we had last weekend. We dumped at least 1/2 of a jug in. Might be too much, don't know. But with the way the water was pouring in and stirring up whatever was sitting on the bottom a full gallon might have been a good idea 🙂
If you're using 3% Sodium Hypochlorite household bleach, 2mg/liter of chlorine would translate into 2/3 gallon bleach for every 10,000 gallons of water in your cistern.
I usually only put in 1/2 gallon for every 10,000 and I make sure to go up on the roof and distribute it evenly down the various downspouts, otherwise i'd be concentrating it right at the pump intake and the water will smell like bleach for a week.
Depends upon what you do with the water...we don't drink it but cook with it and use it to brush our teeth.. the dogs drink it but they drink mud puddles. We've never been sick but there is the potential....that is why I shock it every month or two.
Think of it this way have you ever accidentally drank some water while swimming in a lake? There is very low probability that you will get sick...but if something dies or defecates in your cistern you run the risk of ecoli.
I had a case of ghiardia (sp?) when I was younger...never ever what to experience that again so I think about, I know many locals that do drink their cistern water and don't do much other than check it once in a while for anything floating around in it.
Be sure your overflow pipe has a screen on it to keep out the critters. Anyone who uses cistern water should at a minimum open the cover, check the level and chlorinate if necessary once a month. If the level goes below the foot valve the pump could run and run and fail which means a plumber and a new pump. Cisterns should be cleaned every 2 or so years. Clean the screens on your downspouts like twice a year and especially after a wind storm. Be one with your water supply.

test that addresses
I've been paying $30 per test to Ocean Systems Lab on STX for a residential water check for
Chlorine (maybe? we don't use any)
Total Dissolved Solids
It includes a sample before the filter (cistern) and after the filter (at the faucet). I test annually, every time I change the UV purifying lamp.
usually the landlord or home owner takes care of the cistern, unless it's agreed upon that you will do so in your lease agreement. i've never had to do anything with my cistern, and if there was ever a problem with the water i would have reported it. never had to.
only happened once that i got sick from drinking cistern water, but i could still bathe with it so i did that and stopped drinking it.
i always thought that the extras in the cistern water must make it extra tasty but that's just me. i do have a brita water filter and use that for drinking water... water that is to be boiled anyway, i don't worry about... and when i leave the islands, i cannot even stand to SMELL the water that comes out of the faucets, it's like drinking from a swimming pool, or i can taste the hardness. i am so used to the wonderfully clean "sky juice" now that i am spoiled!
