Biorock Tank Istallation

Drainage & Sewer Works

SB Civil Engineering are now fully trained by BIOROCK to install their variety of tanks. BIOROCK and their systems, they are non-electric sewage treatment plants which use a biological process and are gravity fed, requiring no electricity at all. As a result of this, maintenance and operational costs are extremely low, and reliability is maximized.

We now work with BIOROCK to carry out their installations. We have already been awarded a contract and completed our first installation for them, this was for a site in Rickmansworth. We started with carrying out a percolation test which involves a test to determine the absorption rate of soil for a septic drain field or “leach field”. The results of a percolation test are required to properly design a septic tank system. We then installed the new BIOROCK tank system to replace the septic tank previously there.

The BIOROCK septic system functions as a three stage treatment system. Initially the raw sewage enters a primary tank to provide separation and the breakdown of organic solids (Primary Treatment). The sewage then passes through an effluent filter before discharging into the BIOROCK unit which incorporates the well proven aerobic digestion process (Secondary Treatment) and filtration process (Tertiary Treatment).

We are currently in the process of securing more tank installation contracts with BIOROCK and look forward to working with them and their products in the near future.
