Kindest sterilisers on septic tank system
Hi,
Any advice on kindest sterilisers to septic tanks? I have an old 2-chamber & soak away system that I BioBoost with digesting bugs each month, but we have a holiday cottage here too & guests sometimes use a whole bottle of bleach in a week(!!!), therefore I want to be as kind to our bugs as possible, especially as I plan to up my brewing frequency.
Cheers for any advice,
Tristan

Kindest sterilisers on septic tank system
I just try and reduce what goes down into mine. I try and throw most of it on to the gravel drive etc.
I use the bio boost too, not sure if it makes any difference. Who often do you pump it out? Ours lasted well over 3 years without the boost.

Re: Kindest sterilisers on septic tank system
Chlorine bleach is not as bad as you might think. It is an oxidising streriliser so it will be consumed by organic matter which it will oxidise. The oxidised chlorine products can be more persistent (especially with ammonia), but unless you are using huge amounts of bleach then it should not be an issue. I assume that all waste water is routed to the septic tank and therefore there will be more than adequate dilution, even with a whole bottle of bleach per week.
A more expensive option is to use Sodium percarbonate which forms hydrogen peroxide and sodium carbonate in contact with water. The hydrogen peroxide will oxidise organic matter but will not from persistent breakdown products. Sodium percarbonate is the active ingredient in Vanish and Lidl Formil.
Starsan is a mixture of phosphoric acid and DDBSA. I would not call it a steriliser by any means, but it would have a very low impact in a septic system.
(Pine disinfectants and products like Dettol and Jays Fluid are the worst options; though I doubt if anyone would use these for brewing, but obviously there are always exceptions)

Re: Kindest sterilisers on septic tank system
I think you might be confused with a septic tank and a two chamber tank. The former only took toilet waste and the latter takes all waste water and should be emptied regularly. Whereas the former only needs emtying when full.

Re: Kindest sterilisers on septic tank system
I understand a cesspit to be a large tank that simply gets filled and emptied.
A septic tank is normally a 2 chamber tank, often made of brick and concrete, that uses bacterial digestion to break the waste down before outfalling to a soakaway. Septic tanks only need to be emptied when too many solids build up, which in our case is about every 2 years.

Re: Kindest sterilisers on septic tank system
2 years is about average i think.

Re: Kindest sterilisers on septic tank system
Thanks for the comments. Yes, ours is an old 2-chamber brick setup hidden in a field about 20m from the house, takes all wastewater. Its been emptied once in the 4.5 years we've been here. There was a blockage in the outflow pipe (a fist sized ball of lime!) that I had to rod from 2 sides before it budged.
It's reassuring to hear that the bleach shouldn't affect things too much. I'd thought about using Starsan for cleaning some brew-ware, but was worried it could have effects 'down-stream'.

Re: Kindest sterilisers on septic tank system
Are you sure the blockage was lime and not fat? If the septic tank is more than two metres from the house there should be a grease/fat trap installed before the septic tank.ephemeraldog wrote: ↑Tue Sep 11, 2018 10:49 pmThanks for the comments.

Re: Kindest sterilisers on septic tank system
Thanks for that information - it's all really interesting. Obviously Dettol and Jeyes Fluid are not used for brewing but purely out of interest could you expand on why they are bad for septic tanks etc?
Re: Kindest sterilisers on septic tank system
Jeyes Fluid is based on p-chlorocresol and rar acids whilst Dettol is mainly chloroxylenol. This probably does not mean too much to most people. What these two products have in common is some chlorine and and a ring structure in the molecule, making them quite stable not not readily biodegraded . These two products are suitable for external contact but not for internal use. They will be fairly persistent and have a relatively long half life, far longer than an oxidising biocide like bleach.

I still wouldn’t put a bottle of bleach a week down mine.
Interesting stuff though Carnot.

Re: Kindest sterilisers on septic tank system
Quite sure, we had the whole building repointed & rendered in lime 18 months before the blockage. I guess some of the work crew washed things down into wastewater drains. I think the limeball is still kicking around my garden somewhere.
We have no idea what the build of the septic system is, other than 2 chambers & a run off pipe. It probably dates back to 1970s, not sure what building regs were for tank installations then.
