Septic Tank Systems, Regulations and Pro's and Con's
New Septic Tank Regulations
Septic Tank News: The UK Environment Agency requires all existing septic tanks that discharge, either intentionally, or by accident into a ditch or watercourse, to be replaced by a sewage treatment plant as soon as possible. It is also required if you sell your property.
Failure to comply will result in Prosecution.
What is the Answer?
The cheapest solution is to replace the Septic Tank with a Sewage Treatment Plant. It is much cheaper and less disruptive than installing a new Soakaway Drainfield and over 70% of sites cannot have one anyway, due to failing the Mandatory Tests.
In the past, if you had an old existing Consent to Discharge, it was automatically transferred to a valid Permit , but this is no longer the case. Ireland is also enforcing the new rules..
Sewage treatment plants do not need an expensive soakaway drainfield, as they can legally discharge directly to a ditch, stream or surface water drain.
All septic system installations must conform with the Environment Agency General Binding Rules.
It is estimated that over 70% of sites will fail the Exemption tests and will not be allowed to have a septic tank, so be warned.
These are placed in the vertical part of the 'T' pipe inside the tank at the outlet end. They prevent small solids, hair, lint, etc. from exiting the tank and blocking or clogging the soakaway drainfield.
It is estimated that they reduce suspended solids in the final effluent by around 60%.

Advice and Information
On this website you will find details and advice on any sewage system or drainage problem you may have.
Whatever your tank and drainage needs, we strive to give a first class service. We supply both domestic and commercial customers with first class professional drainage services throughout the UK.
Specialist pages have been created, explaining your off-mains sewage treatment options, explaining the design and operation of the septic tank and soakaway drainfield, plus what to do if you have drainage or sewage problems. A septic tank is rarely the best solution for a sewage system as sewage treatment plants are ALWAYS a better and cheaper option.
The Environment Agency has told us that soakaway crates are NOT acceptable for any wastewater soakaway, as they do not conform to the Building Regulations or the BS 6297 2008.
Crates are only allowed for rainwater soakaways. Report the Cowboy Traders to Trading Standards.

Surveys and Reports for homebuyers and problem sites
Regulations have been set for minimum treatment standards, construction and replacement of brick, concrete and plastic septic tanks and drainfield systems. These are covered in the Building Regulations H2 and BS 6297 2007. Most solicitors require the vendor to show the status and location of the treatment system when a house is sold and many systems, particularly septic tank systems and cesspits, do not pass the survey. Septic tank systems that fail the survey have, usually, to be replaced with sewage treatment plants, but we have had a couple of sites where even this is not possible.
If you are buying a house with a septic tank, ALWAYS have an independent specialist septic tank and drainage survey done on your septic tank system before purchase. It can save you a lot of grief and money later.
