New regulations will dictate that you must register your septic
system. This new legislation is an EU directive and is already in
force in Wales, Scotland and Ireland and it is expected to be enforced
in England soon. People with septic systems in England do not currently
have to comply with these regulations but we do recommend that you are
familiar with them and it would be prudent to plan ahead and get
an idea of where your system will stand and whether or not you need to
budget for any future expenditure. Different systems, locations and
the potential for a system to pollute, will dictate how the system
needs to comply with these new regulations. There are many
variables to consider but the overall process of establishing what
applies to your system is straight forward. Some owners of existing and
certainly installers of new septic systems will for instance be
required to apply for 'A Consent To Discharge Clean Water' so that they
can discharge a 'cleaned water' output from their sewage treatment
plant, directly into a river. In this scenario; if we are talking about
any NEW systems, then The Environment Agency will also need a certificate from 'Building
Control' department before they will grant any consent, to show that the system
has been installed according to ‘Building Regulations' and so on.
However DON'T PANIC! Most domestic systems will achieve an 'Exemption
Certificate' but people will still be expected to empty and maintain
their systems on an annual basis and to keep records for any potential
inspection by The Environment Agency in the future. We recommend
that you first contact 'The Environment Agency' and you should find
them very helpful indeed:
Please follow this link if your system is located in WALES.
Please follow this link if your system is located in ENGLAND.
We expect them to advise and support you through the process and
give you confidence that you are taking the correct route
forward and making the right decisions about your septic system.

Your septic system & how it works
The folklore of septic systems could probably fill a small book. Like most
folklore, the stories reflect elements of truth but they also evolved from ignorance
and humour. It is time to get down to the facts. Septic tanks are in general a natural, sewage
treatment system. These systems rely on common bacteria to literally digest & process
the sewage turning solids into liquids & gas (smelly!). The overflow liquids are then
piped to an in-ground soak-away system, where final purification is done by soil organisms.
It is important to make sure that the soak-away; or drainfield or septic drainage system as it
is also referred to, is kept free from any solids and so the septic tank needs to be emptied on
a regular enough basis and the t-pieces must be in place. Sewage treatment plants are much
better at assisting this water purification process and they can disperse a relatively clean
waste water, although we wouldn't recommend drinking it. Sewage treatment plants can discharge
directly into a water course, providing a 'consent to discharge' from 'The Environment Agency' has been granted.
The impact of modern living
Because of our busy, gadget dependant lifestyles, modern cleaning and washing habits and
the availability and use of many household products, the modern septic system struggles
to tackle the increased quantities of liquid wastes that are flushed from the average
household. The working bacteria are compromised by bleaches and other household products and cannot
function as they would have done in the olden days. Therefore, any solids/sludges which the diminished
bacteria is unable to break down, needs to be taken away periodically for disposal and
further more intensive treatment at the local sewage works, where everyone else's sludges go.
A 'system empty' needs to be done usually every one or two years depending on the size, type &
condition of the individual septic system however, 'The Environment Agency' and new regulations
are recommending that this is an annual event. Your system may even need a more regular empty than this,
where the 'water table' is normally an issue or where a treatment plant is not large enough.
In any event, detergents & other household products which we all use today, only go to slow
down natures process in the tank. This means that the sewage needs to be disposed of at
more regular intervals to prevent 'system overflows' (pollution). This will also prevent soak-away
and septic drainage pipes from becoming packed and when jetting cannot unblock these pipes, a
solution can become very expensive indeed.
What about using system additives?
So far, no additives like enzymes or chemical de-greasers have been scientifically proven
to reduce the need to have your tank emptied less often as they claim to. These products or other
bacteria's added would only compete with the natural bacterial process further. If one really
wants to reduce the frequency of emptying the tank, try to reduce the introduction of none
biodegradables or household chemicals into the system. This means do not pour bleaches or chemicals
down any of your sinks or toilets and try to use baths, dishwashers and washing machines much
less frequently. There are environmentally friendly household products widely available from
your local superstores which can help you achieve some success. Please remember that whatever
anyone claims to achieve, 'the Environment Agency' advice does not discuss additives at all and
the new regulations are gearing up for everyone on a private septic system, to have their systems
emptied at least once a year!
Other common myths
Most theories about 'starting up' or 'priming' a new septic system deal with the notion
of 'seeding' so as to get good bacterial activity going at the start of a new septic system.
This traditional advice ranged from seeding with a pound of yeast, with animal manure and even
by placing a 'dead cat' or other dead animal into the tank! Like us, 'The Environment Agency'
simply recommends that you do nothing. The simple act of using and emptying the system on a
suitably regular basis is all you need to do for your septic system to function as it should.
Remember: Don't sit on it for tooo long!
It is good to be 'regular'! Those who never have their tanks emptied at all are running
a serious risk of damaging or packing their soak-away systems permanently & incurring large
repair costs as a result! Furthermore, the town sewage treatment works where all of your
domestic sewage waste is disposed to are now testing the density of the sewage loads disposed.
The longer a septic tank is left then the denser the solid mass is and through waste testing, one
may incur a premium charge to dispose so . . . don't sit on it tooooo long!
