Why we should be your first port of call.

Friday, 04 May 2018

When issues start occurring with your Sewage Treatment Plant or Septic Tank it is only natural that the worst is assumed, however it may be something simpler than you think! Needless to say all the necessary precautions should still be taken, if you are genuinely concerned about your tank we would always recommend to err on the side of caution.

Towards the end of March we were contacted by a large estate in County Durham as they were concerned about the functionality of one of their sewage treatment plants, the small cottage was served by a BA BioDisc and to determine the root of the issue we initially sent one of our servicing engineers to check that the system did not require any replacement parts.

As the system had not been serviced up to this point there were some parts that required replacing, the most notably of which was the motor/gearbox. However this was not the only issue and it was abundantly clear there were other forces at work causing the system to back up.

Step in our Contracts Manager Ian Murray who attended the property shortly after to identify the issues with the treatment plant as it was clear it was not a mechanical element that was failing. Once on site it was swiftly determined that the issue was in fact the soakaway was blocked and was no longer draining away.

As soon as the issue was diagnosed percolation tests were then carried out to determine where would be the best location to place the new system, three different test pits were used as an indication of the porosity which on this occasion was quite poor. We did need to take into account that prior to this we had just experienced some severe weather conditions with a large snow fall followed by continuous rain meaning that the ground was at its most saturated.

To counteract the poor ground conditions we opted to install the soakaway at a slightly lower level to allow a gravity fall from the BioDisc treatment plant.

The proposed scope of works was to find and located the existing outlet pipe after the outlet inspection chamber after the system has initially been emptied, we would then install a slow bend and an estimated 15 metres of 110mm pipework running directly down the adjacent field. We then installed a shallow inspection chamber before we installed before installing 40 metres of 1.2 metre wide drainage field in a ‘U’ shape comprising of 110mm slotted pipe, bedded and surrounded in a clean washed gravel with a geotextile sheet above.

After the new drainage field was installed the servicing engineer was required to re-attend to complete the remedial works and fit the new parts required to get the system working as designed. With regular maintenance and desludging this system has extended its lifespan considerably.

If ever in doubt, let us be your first port of call, we can arrange for either a servicing engineer or a contracts manager to attend site to assess the situation. For more information why not give us a call on 01388 537030.

Feedback From Satisfied Customers

  • I have recently had a new sewage system installed at one of my sites which wasn't a straight forward job due to it being located in a private field, we had to make sure the owner, as well as our residents were happy with the proposals. Ian Murray met me on site on 2 occasions, with the owner of the field ans was very professional and explained exactly what would be happening, putting the field owners mind at rest. The job went to plan with no unexpected costs and minimal disruption to the field. Very happy customer!
