It may not be the septic tank at all - it could be the pipework cracked or broken through the dryness we are experiencing ( subsidence,retraction of bedding earth/rock debris , etc ) if the run of the pipework to the septic tank is some distance away from the property ! Domestos or bleach is only a temporary measure , as it not only kills the bacteria that keeps the contents of the tank from smelling , but can corrode the joints in the system through electro chemical action!stgeorge

 While the Fosse Septique products work very well, you are not supposed to smell anything vile whatsoever.

The fact that you can points to a problem with your venting. In the course of normal degradation various gases are given off.

If you are getting these smell indoors be vigilant. Being able to smell stuff indoors means that your tank is incorrectly vented and could possibly lead to a build-up of harmful gases. Without trying to frighten you, some of these like Methane are flammable and if you are getting these smells indoors it means that your house has the gases roaming around.

Pay particular attention to all seals from toilet waste pipes, and indoor access points and then establish that you have a vent pipe above the roof line of your house, which is clear.

If you're ony getting this smell outdoors near the tanks, buy a product that is designed to START a septic tank. Usually the beneficial bacteria get killed off just before you have visitors by a liberal dose of Domestos down the hatch. Never use any product in your toilets unless it's designed specifically for use with septic tank. Otherwise it willl instantly reduce a perfectly good working tank to a pile of s***e.

It might be worth checking that the waste is not leaking BEFORE it gets to the tank, it can't degrade propery there.

It's also possible that you're outflow pipes from the tank are blocked through age and you tank is simply full. It's easy to get the vacuum company in and start it all off again. this usually happens as your home gets filled with guests and normal evaporation cannot keep up with all the flushing. This is normal for a tank where the outflow is not great.

Best regards,

Recently we had some off-and-on vile smells, but before we went with the specialists we tried a product that's worked a treat. It's a special 3-in-one super action fosse septique problem solver: you start with the green sachet for one task, then 3 days later the red one, and then five days after that the gold one (or something like that).

It's available at the Vence LeClerc (and probably at the La Colle one too) I can't remember the name, but you'll find it in the same section as the treatment powders - look for the graphic explanation of the 3 steps on the packaging... It could be worth giving that a try first...
