Septic tanks are a traditional solution for domestic sewage disposal, they are ideal for situations where access to mains sewer is not possible or practical.

Formed from a single chamber, the sewage from a domestic dwelling is collected and retained in the tank. Time allows it to be anaerobically digested, breaking the solids down into sludge. The excess effluent liquid then flows from the tank out of the outlet, and then most commonly into a suitable underground drainage field system.

These Marsh horizontal septic tanks have a heavy duty shell to ensure they can be installed in all sorts of ground conditions, and they also have integrated lifting eyes for handling the tank on-site. The tanks are CE marked and certified to EN12566-1 Annex B confirming that this range complies with Construction Product Regulations.

Please note: this tank comes complete with a pedestrian cover and frame.

Why a horizontal tank?

The horizontal design of this septic tank can save you money on site! You won’t need to excavate as much as you would with a traditional spherical tank, meaning it is usually quicker to install and reduces the chance of ground water issues. It’s a win-win! This design also means you can install a tank in areas with a higher water table or hard rock site conditions. They're also known as shallow dig septic tanks.
