2020 General binding rules (GBRs) which came into force on 1 January 2015 are designed to reduce the level of pollution from sewage in the nation’s watercourses
According to the GBRs, if you have a septic tank that discharges directly to surface water, you must have upgraded or replaced your tank by 1st January 2020 (alternatively you must have plans in place to carry out this work within a reasonable timescale, typically 12 months).
1 Connect to main sewer
This may not be possible in remote locations, although pump chambers can be used to direct wastewater to the mains sewer.
2 Install a drainage field (Designed in accordance with BS6297)
This allows the septic tank to discharge wastewater into the ground instead of surface water. In many cases, the installation of a drainage field is not possible due to site constraints such as space and/or the soil not having sufficient drainage potential (ie, rock, clay, high water table).
3 Install a Uni:Gem STAR septic conversion unit
A Marsh Uni:Gem STAR can be installed and connected to a pre-existing septic tank. This treats the septic tank effluent to a sufficient quality allowing it to be discharged to surface water.
4 Replace your septic tank with a Marsh sewage treatment plant
A Marsh sewage treatment plant eliminates the need for a drainage field or septic conversion unit and ensures that the wastewater is fully treated before being discharged.
The Marsh Uni:Gem★ septic conversion unit is to our knowledge the only system available on the market to UK merchants that is fully tested and accredited to BS EN 12566 standard. Effluent discharge from these units exceed the minimum requirements for BS EN 12566.
