NOTES

1.Septic Tank Conversion Units

Septic tank with a separate secondary treatment unit approved under BS:EN12566 may be used to discharge treated sewage effluent to a watercourse without requiring an environmental permit, presuming that all the general binding rules are also complied with. In-tank retrofit kits can only be used if the operator first applies for and is granted an environmental permit.

2.Non-Electric Sewage Plants

There are a several non-electric sewage plants being introduced into the UK market, where these units require an additional primary chamber, please ensure that the primary chamber being supplied is the same both dimensionally and in volume capacity as the product that wasted for EN12566-3 certification, failure to do so could invalidate the certification process test

3.Nutrient Information

Ntot reported as Ntot, TNb or TKN in the test report.
