bioTank is our Irish designed and manufactured waste water treatment tank. It is manufactured from high strength concrete and is certified to the EU standard, EN 12566-3. The tank is a single structure which means it is easier, more economical and requires less space to install than a standard septic tank. There are no mechanical parts within the tank which keeps maintenance and running costs to a minimum. The tank also supports the standard influent range now insisted upon by many county councils.
