The Ensign domestic sewage treatment plant comes with lifting eyes to make and unloading and installation faster and safer. We designed the Marsh Ensign 6 plant to self-level on the base and with our unique pipe connections ensure the installation is undertaken efficiently and correctly. The six person Ensign Sewage plant is extremely strong and is only 1.95m in depth with an inlet invert of 500mm, this design reduces both the time and cost of installation, in normal ground conditions the unit only requires a pea-shingle surround. For guidance ideally the Ensign plant should be 7m from a dwelling or10m from a stream.
