Foul Drainage Systems
We have installed many systems over the years and we have seen great advances in the treatment of foul waste in private systems.
No longer is there any concern when a property is beyond the main sewer – we have systems which will cope with all situations and can exceed Water Authority main sewers.
The Environmental Agency has played a large part in contolling pollution from old and outdated systems – further stringent controls were introduced in November 2019 which are detailed below. We believe Graf drainage systems provide the technical knowledge to ensure their plants will meet the requirements now and for the future.
