Below you’ll find answers to the questions we get asked the most about.
If you own a property then you must have one or the other, but you must also make sure you follow the rules and be legal.
If you are looking at going down the route of installing a septic tank then the discharge can only go to a soakaway not to a watercourse, you can do a percolation test in the area that will determine the size of your soakaway.
If you have very poor ground that will not soakaway (percolate) and a soakaway isn’t possible then you will need to invest in installing a sewage treatment plant that can then discharge directly into a watercourse i.e. river stream or ditch.
All septic tanks and sewage treatment plants are now manufactured to a standard EN12566/3 or EN12566/1 for septic tanks.
These standards are put in place so that manufacturers manufacture the tanks to set guidelines to prevent pollution.
One of the guidelines is that each tank must have storage of at least 12 months sludge (sewage) for the size of the tank.
i.e. 6 person treatment plant if you have 6 persons living in the property then you would need to consider desludging the tank annually if only 2 person live in the property then you could probably leave it for three years .
but how to check visually would be to lift the lid on the septic tank or treatment plant and check to see if the sewage or the crust as they say on the surface of the sewage is near to the top of the baffle wall.
The sewage or crust must stay below the top of the baffle and not left to get to high and end up in the other chambers.
The answer is no, you can only flush things that will break down in a short period of time, none biodegradable products should not be flushed I.E towels, wet wipes, earbuds, etc.
Also all cleaning products must be kept to a minimum as these will kill the bacteria that helps clean the effluent, if the bacteria dies then the treatment cycle dies and the then the tank will start to go septic and smell.
