There has been very little publicity about BS EN 12566 of late.  But did you know that in order to comply with Building Regulations part H2 in England and Wales you now have to install a treatment system that complies with the new European Standard.  Don't just take my word for it, here is what WPL say on their website:

DON’T FLUSH YOUR REPUTATION DOWN THE DRAIN!

Architects, Consultants, Installers and Merchants are advised that there is a significant change to legislation, regarding small wastewater treatment plants, of up to 50 population equivalent.

The introduction of the BS EN 12566-3, means that only products which have been type tested and approved to this new European standard, will be available to the market.

Products which are described as either ‘designed in accordance with’, ‘compliant’ or ‘conforming with the requirements of’, but are not CE marked as a complete system, will not demonstrate full evidence of successful type testing at a European approved test house will not be legal, and will be the subject of a trading standards investigation.

One way to avoid potential embarrassment when specifying equipment for future projects is to ensure you are recommending package sewage treatment plants which are fully compliant, and already carrying the CE marked in readiness.

BS6297 has been modified to detail how water from sewage treatment systems should be disposed of.  It details the use of soakaways, reed beds and mound filtration systems but does not now detail the equipment design as it used to.

The upshot of all of this is that if you are involved in putting a new sewage treatment system into a property make sure that it is CE marked to BS EN 12566 standards.  Any system that is not certified to this European Standard is not legal in the UK.

All Biokube models up to 50 PE are CE marked and have been through the strict testing procedure laid down by BS EN 12566 - 3 2005.
