O’Reilly Oakstown manufacture, deliver and install precast concrete Septic Tanks for homes and domestic dwellings in Ireland. We have a range of tank sizes available. Our 3400L septic tank is ideal for new builds or for upgrading your tank from a lower quality one. Our costs start at €1150 + vat for a 3400L tank.

Installation of Septic Tanks

We offer a full installation service, supplying, fitting and commissioning each system. When installed, our septic tanks are fitted flush with the surrounding ground level – no unsightly equipment protruding above ground.
