Spherical Septic Tank ‘Onion’ Style

Marsh Industries

The Marsh traditional ‘onion’ style septic tanks are suitable in areas where you can form a percolation or drainage bed. As the treated effluent is not to a standard that can be discharged straight into the water course, it requires further treatment through the soil.

At Marsh Industries we only use 100% virgin resin (no chalk fillers) in all our products. Lead times for septic tanks are normally only 5-7 working days.
Advantages of using Marsh:
• Easy installation with ‘keying-in’ lip and lifting eyes
• Has a flat bottom so that it doesn’t roll during installation
• Can be installed in pea-shingle
• Tested and certified to BSEN12566-1
• 50 year design life
• 25 year structural guarantee
• Shallow option available for areas in high water table of hard rock conditions
