Our priority when quoting for any works to be undertaken is to ensure that the most cost effective and suitable solution is provided for our customer. This requires a thorough evaluation of what is on site and what criteria needs to be met to conform to all current rules and regulations. The proposed solution is always dependent on the individual circumstances for each property.

When you have a septic tank installed that discharges to a watercourse a solution must be sought in a prompt and reasonable timeframe, this is due to the fact that under the 2020 General Binding rules you can only discharge to a watercourse with a suitable package sewage treatment plant.

Whilst undoubtedly our favourite system for operational efficiency is the Klargester BioDisc unit, however one size does not fit all when looking at the most suitable solution to suit the application. This could be down to invert depths, working area, ground condition or even just the aesthetics of the covers.

Due to limited space within the garden area a smaller access cover was preferable, this meant that the choice for the sewage treatment plant was limited as the larger covers on the BioTec and BioDisc units would have drastically reduced the garden area.

Therefore the Bioficient 1 was the ideal solution as the unit has a small lid which lays flush to ground level. To limit the disruption to the working area we proposed to intercept the existing inlet drainage and divert to the new installation location which was parallel to the old septic tank.

As the Bioficient 1 is certified to BS EN 12566-3 we were also able to utilise the existing outfall to the watercourse, however due to the levels of the outfall drainage a pumped unit would also be required. This was a further reason why the Bioficient 1 was the preferred option.

As all of the electrical components of the Bioficient 1 are located external of the unit, in the case of a power failure the pumps would be unable to operate and if this was not rectified promptly this would begin to back up the drains.

With all electrical elements being above ground level, if the system does back up there is less chance of this needing replacing.

With the new system now installed and commissioned we could fulfil another requirement under Building control regulations which was to ensure that the old system had been appropriately decommissioned.

This included having the tank emptied in full before breaking into the old casing, infilling and compacting with a granular material, this would then be overlaid with excavated spoil to avoid any potential future settlement.

Each of our installations is individually tailored to suit the customer and site with no two scopes of work being the same, for more information of the installation services we can offer please don’t hesitate to give us a call.
