Spherical Septic Tank Onion Style
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.
