Biofriendly Risers

We offer “Risers” for Biofriendly Systems, in order to raise the height of the tank inspection hatches (manhole covers) if required.

We can supply 2 or 3 different Riser heights for different invert / inlet levels, which allow the Biofriendly system to be positioned at the optimum depth for each individual installation.
The wastewater flows from your home to your Biofriendly system via gravity, (unless you have a pumped system), and the position of the inlet pipe determines the depth at which the unit should be installed.

Biofriendly offer riser at heights of approx:   380mm,  760mm  & 1140mm

However, we also offer Risers of other sizes, to order, if required.
