Simply put it is the new customary for sewage treatment plants that are sold within Europe. The Construction of Products Regulations from 1991 now state that any sewage treatment plant that are sold within the EU must have the subsequent specifications -
1) Should be a hundred percent watertight
2) The sewage treatment plant has to be structurally sound
3) Must have a reasonable capacity to hold waste water for an enough time before needing to be emptied. This lets a maximum a period of time for the sewage to be handled, for that reason the discharge will be more environment friendly and the sewage treatment plant will be a lot more effective.
All of these necessities are complying with the British Environment Agency commandments, which is not optional. All manufacturers and suppliers in the United Kingdom need to be able to prove that the sewage treatment plants that they sell are compliable with the regulation set out buy the British Environmental agency. Which means all sewage treatment plants must give evidence that is satisfies the standards in paragraphs, five, six point two, six point three, six point four and six point five of the B S EN 12566-3.
And the British Standard Institute said that they only want sewage treatment plants with a EN12566-3 2005 Certificate on the United Kingdom market. The Environment Agency have also said that only sewage treatment plants that have the EN 12566-3 2005 Certificate are allowed to obtain the Environment Agency Exemption Certificate which you have to apply for, however it is highly recommended.
Because these restrictions apply to all of Europe you will be unable to import an inferior sewage treatment plant from mainland Europe.
Although the EN 12566-3 has very high guidelines and tests, it requires only a percentage reduction of the sewage effluent and therefore it does not guarantee that the final effluent will please the Environment Agency Consent Standards that must be satisfied. Another abnormality is that the manufacturer may test a certain quantity of litres of sewage each day for only four people, nevertheless they have the right to sell the tank for 6 individuals if it has the adequate space.
