Shallow Ensign:Standard™

Marsh Ensign Shallow Dig

Tough ground? Tight site? Go shallow — dig less, install faster.

The Marsh Ensign Shallow Dig offers all the performance and reliability of the trusted Ensign range — but with a compact, low-profile design that makes it easier and safer to install on sites with challenging conditions.

Unlike standard systems that often exceed 2.3m in depth, the Ensign Shallow stands at just 1.6m high, reducing excavation requirements, lowering install costs, and making it ideal for sites with:

• Hard rock or difficult ground

• High water tables

• Limited excavation depth

• Restricted access

Built for Easy Installation

With no internal moving parts and a compact design, the Ensign Shallow is simple to position, quick to commission, and easy to maintain — especially on complex domestic sites.

Proven Treatment Performance

Tested and certified to BS EN12566-3/A1:2009, the Ensign delivers outstanding results:
11.5:19.2:8.4 mg/l (BOD:Suspended Solids:Ammonia), equating to up to 97% pollutant removal.

PE Range to Suit Any Project

Available in sizes from 4 to 35 PE, with options across Standard, Ultra, and Shallow designs — plus a wide range of ancillaries and outlet types to match your specific consent or discharge needs.

The Ensign Shallow makes the job easier, faster, and safer — without compromising performance.
Perfect for domestic properties, tricky sites, or time-sensitive installs.
