Envirocare P6 vs Ecotanks wastewater treatment system

My brother is in the middle of a self build in Sligo and had planned to get a treatment system from a company based in Donegal [broken link removed] but then he got a call today from a rep from Envirocare advertising the P6 system. He's wondering if it's a better option because Envirocare are well known as opposed to the other company.

The Envirocare website is under construction at the moment so I can't read up on it, so does anyone have either of the systems and which one would be the more favourable option? Both have an agrement cert and the prices are similar enough.

Any information is appreciated, thanks.

any system thats agrement certified is acceptable.....

I think (open to correction) that Envirocare re-sell a product by a company called Klargester. Maybe try googling that for info.
