IISI

The solution is IISI.

IISI is a biologic-chemical wastewater treatment unit that is installed on the top of an existing septic tank. Installation can be carried out year round, as no excavation is needed.

IISI system includes EkotekoBox – a chemicalizing device that is installed indoors to improve the phosphorous removal.

IISI unit, installed on top of the last septic tank, works as a bioreactor that effectively removes both the organic matter and nitrogen from the wastewater. IISI wastewater treatment unit fulfills the tighter removal standards that are defined in the Onsite Wastewater System Decree (542/2003).

Of course, if you prefer, you can install IISI on top of a brand new septic tank too. This is, in case if your old tanks are in poor condition. We also deliver septic tanks.
