Marsh Euro Septic Tank

£740.00£1,119.00 EX VAT

A traditional bottled shaped septic tank used together with a drainage field. Has a unique filter to help prolong the drainage field life.

SKU: EuroSeptic Categories: ,


The Marsh Euro:Septic, like other onion shaped septic tanks, holds sewage and allows solids to settle into sludge at the bottom of the tank. Here it is naturally broken down by a process known as anaerobic digestion, which promotes settlement of the solids and some biological treatment. The effluent is not fully treated and must receive additional treatment before discharge to the water environment – the most common method being to discharge via an underground drainage field.

The bottle-shaped Euro:Septic is tested and certified to EN12566-1 Annex B and benefits from an outstanding hydraulic efficiency of 99.63%.

The Marsh Septic Tanks are available in the following sizes:
