Marsh Ultra Shallow dig range of sewage treatment plants are ideal for areas that suffer from a high water table or hard rock conditions.
The shallow range of sewage treatment plants are manufactured using the same materials and techniques as the Ultra Standard range. It just requires 30% less excavation due to the reduced height of the tank.
External Cabinet can be supplied free of charge, please state when ordering.
Benefits;
Advantages of using Marsh Sewage Treatment Plants:
No moving parts
- Low running and maintenance costs
- Easy installation with lip and lifting eyes
- Tested and certified to BSEN12566-3
- 50 year design life
- 25 year structural guarantee
The Ultra plant has been tested to EN12566:3-2005 this is highest testing standard for European testing. The high test results mean the Ultra can discharge direct to a ditch, watercourse or percolation bed.
The Ultra domestic sewage treatment plant comes with lifting eyes to make and unloading and installation faster and safer. We designed the Ultra plant to self-level on the base and with our unique pipe connections ensure the installation is undertaken efficiently and correctly.

Bio-media
High specification bio-media (310m3 per m2) and membrane diffusers ensure even circulation to eliminate ‘dead spots’. The bio-media is contained by a stainless steel securing mesh to ensure no migration during handling or potential flooding. -
Stainless steel mesh
Retains media in aeration chamber during transportation and handling, and in the event of flooding. - Final settlement chamber
-
