As a leading ‘off mains’ solution provider throughout Hertfordshire and surrounding Counties, we have seen a substantial increase in the number of calls relating to the replacement of failed septic tanks with modern packaged sewage treatment plants throughout 2014. This is partly due to the winter storms of early 2014 causing much of the Country to receive excessive amounts of rainfall, resulting in flash flooding and a rising water table. The rising water table and saturated ground conditions caused many septic tank soakaways to fail.
We were contacted by the owner of a property on the outskirts of Stevenage in Hertfordshire after they had experienced several months of their septic tank flooding in early 2014. The homeowner wanted to replace the existing septic tank and drainage field with a system that would operate effectively throughout the winter months.
Upon inspection, it was found that the foul drainage from the property to the existing tank was in good condition with no fractures or dislodged joints. Located on the boundary of the rear garden was a field ditch which would provide a suitable location for the disposal of treated effluent.
Mantair engineers recommended the installation of a packaged sewage treatment plant and remote Beehive blower housing. The treatment plant was installed with a ‘pumped’ outlet ensuring that the system would operate effectively even if the receiving ditch became flooded during periods of heavy rainfall.
Throughout the duration of the works Mantair engineers ensured that the impact on the garden was kept to a minimum.
