Frequently asked questions

Septic tanks and their drainage fields can fail for several reasons. a. the tank itself may need emptying, you may have overloaded it (i.e. the tank may be too small to manage the quantities of waste water being produced) or, b. it should never have been installed there in the first place i.e. the ground may be unsuitable for filtering effluent from a septic tank which means technically the drainage field has failed. Unfortunately, you won’t know that until the evidence becomes apparent, which might be a foul smell, or solids appearing on your lawn.

At this point, your system will not have been working effectively for some time and will almost certainly have already caused local pollution.

Don’t forget that homeowners with septic tanks In England that discharge directly into surface water will need to replace or upgrade their drainage either when they sell their property as soon as possible. 

Septic Tank Converters cannot be used to demonstrate compliance with the General Binding Rules (Binding Rules 2020, DEFRA, January 2015).

One of the most important factors in determining the choice of sewage treatment product is the site’s drainage properties. Both septic tanks and sewage treatment plants typically require a drainage field into which they discharge effluent. Testing the ground for its permeability is usually done by professional installer using a percolation test; the correct procedure is described in BS 6297:2007. Note: your property will need to be located on highly permeable ground if you want to install a septic tank otherwise the drainage field will fail. At least half the UK sits on a clay substrate, ruling this solution out and making a sewage treatment plant the only viable option.

The propensity of the site to flood and the height of the water table are also important considerations. Both H2 building regulations and BS 6297 state that the water table must be at least one metre below a septic tank outlet. In this instance, and if your property is in a flood risk area, you will need to install a sewage treatment plant.

Don’t forget that homeowners with septic tanks that discharge directly into surface water will need to replace or upgrade their drainage either when they sell their property or before 1 January 2020 whichever is sooner (Binding Rules 2020, England).
 
Follow your system manufacturer’s instructions but always think very hard before putting anything down the toilet, or down the drain, if you have off-mains drainage.  

As a rule of thumb, use general waste to dispose of sanitary towels or tampons, disposable nappies, baby wipes, incontinence pads etc, rather than flush down the toilet. It’s also advisable to avoid chopping and changing to different brands of cleaner or washing detergent.
