BIOROCK FAQs | Residential Wastewater Treatment FAQ

What distance is required between the septic tank and the treatment unit?

Our answer:

We recommend a distance between the septic tank and the treatment unit of 1 metre in our instructions, in order to leave ample work space for installing the connections. Otherwise a depth of fill of 30 cm should be adhered to.

However, you can move the treatment unit as long as adequate slope is maintained to ensure gravity flow. We suggest using risers and a lifting station if necessary.
