Product Description

The Marsh 14,000 Litre Shallow Dig Septic Tank is a horizontal GRP septic tank for sites where digging deep is difficult. It holds 14,000 litres (3,076 gallons), and it is tested to EN 12566-1.

Sizing a 14,000 Litre Shallow Dig Septic Tank

As a guide, BS 6297 sizes a septic tank at 2,000 litres plus 180 litres for each person, with a minimum of 2,700 litres. On that basis, this tank suits up to about 66 people. Because it is a shallow dig design, it is ideal where the water table is high or the ground is rocky.

Key features

  • Shallow dig horizontal design
  • Tested to EN 12566-1 and CE marked
  • Ideal for high water tables and rock
  • Choice of inlet depths
  • Made by Marsh Industries

Options

Before adding the 14,000 Litre Shallow Dig Septic Tank to your basket, choose a deeper inlet if your drain arrives lower than standard. The price updates as you pick each option.

Installation

Depending on ground conditions, the tank can be backfilled with granular material or with concrete. However, if the water table rises above the base of the tank at any time of year, it must be set in concrete. The same applies on clay or other ground that does not drain freely. Using the wrong backfill can void the manufacturer’s warranty, so please agree the method with your installer first.

Specification

  • Capacity: 14,000 litres (3,076 gallons)
  • Length: 5806mm
  • Width: 1816mm
  • Height: 2316mm
  • Standard inlet depth: 700mm
  • Empty weight: 400kg
  • Pipe size: 160mm
