I am no expert but the bacteria has to have some time to digest the sewerage componant before the discharging water will be safe to soak away into the surrounding land. It is not normally to put rain water through a septic tank, this normally goes to seperate soak aways, often several one for each down pipe. -- Charlie Pridham, Gardening in Cornwall www.roselandhouse.co.uk Holders of national collections of Clematis viticella cultivars and Lapageria rosea |

Well apart from the fact the muck doesn't stay in the tank long enough to acted on by the bacteria effectievly the sludge gets washed into the soakaway blocking it up... -- Cheers Dave. pam is missing e-mail |

Septic Tank: how often to clean?
On 3 Dec, 15:43, Eddy Bentley
wrote: Forgive me asking this "odious" question in this group, but I know that a lot of keen gardeners live on isolated properties which are not connected to the usual sewage system. We have a reasonably-sized septic tank embedded in the front garden and we understand that the previous owner had it cleaned every year, at a cost of about £120. There has been a suggestion that this annual cleaning is a bit excessive. On the other hand, I have read that if the solids mount up and leave the tank and move into the soakaway area then the soakaway area becomes clogged and you then have to build a new septic tank at another (clean) spot - which is a real bother and a considerable expense. So, clearly, regular cleaning is worthwhile. But how often is regular for a two-person household? Any ideas? Thanks, Eddy. This post was also put onto UK DIY and it is interesting that nobody here picked up on the fact that this septic tank has a soakaway rather than an outlet to a waterway - it has been assumed that this is a herring bone type. The OP hasn't had the courtesy to come back on either thread and answer the questions posed to him. His concern was that any overflow would block the soakaway system and there would be considerable cost and difficulty rebuilding it. On that basis he is probably right it get it maintained annually, for peace of mind if nothing else. I would like to challenge the vociferous cries from Sacha, Mary Fisher, et al about the use of household chemicals and septic tanks. I live in area of septic tanks - there must be around 20 in this community, and one thing that is clearly apparant is that anyone we know well here does NOT pay service to looking after their septic tank bugs. I will admit to not having gone round my friends here and done a detailed survey off their cleaning habits, but all (I think) have dish-washers, washing machines, etc and I am totally unaware of them taking any precautions with powders, etc. What I am aware of is that like us they pump out every 10 years or more and have no problems with their tanks. These are typically 70 year old double brick tanks that drain into the local water courses, which are all healthy burns. Rob |

Others have asserted that their tank has never been 'cleaned' too, it shouldn't be necessary. Mary |

Mary Its a pity really that we did not make clear at the beginning of this thread that these tanks need de sludging not emptying, and the amount of build up depends on how much usage as well as the design of the tank and lay of the land. A large tank of old fashioned design will seldom need attention and will tolerate abuse, where a modern tank will need de sludging more often and will work a lot better if some attention is payed to what goes in it. Here I do speak from some experiance, having had to cope with ship board systems that were physically very small for the numbers of people they had to cope with. -- Charlie Pridham, Gardening in Cornwall www.roselandhouse.co.uk Holders of national collections of Clematis viticella cultivars and Lapageria rosea |

I'm sure that's right but it really does amuse me about The Authorities' ideas of 'safe'. You'd think that the Earth was sterile, that all animals from the smallest to the largest didn't deposit their excretions everywhere :-) And when it comes to burying animals and people in other than 'authorised' places ... well ... !

Here I do speak from some experiance, having had to cope with ship board systems that were physically very small for the numbers of people they had to cope with. I'm wondering whether it might be an idea to build one ... We'd like a compost toilet but can't find instructions anywhere, CAT wasn't helpful. Mary |

Eddy. Oh come on Eddy - it's clear that we've all been wandering around in the doo-doos asking what sort, or age, etc. of septic you have. It would have put us out of our misery if you had really read the answers, realised our difficulties and answered them. 'Hasty response' doesn't come into it - if you want a reliable answer you have to help us to help you. It is a common problem that queries are raised in this Forum without adequate information - fair enough the OP very often doesn't know quite what to ask, but he /she then typically disappears and doesn't either say thank you or leaves us wallowing trying to answer a question without all the facts.

Considering the overall volume of my 70 year old tank (2 chambers of near enough 100 cubic feet) I can understand why it is more likely to withstand some abuse when related to the modern fibreglass bottles.
