Shallow Ensign:Ultra™
Shallow Ensign:Ultra™ - 6 / Gravity is backordered and will ship as soon as it is back in stock.
The Marsh Ensign:Ultra Shallow Dig brings premium treatment technology to sites where depth is limited but performance can’t be compromised. With a compact height of just 1.6m, it's ideal for installs where traditional tanks can’t go — such as rocky ground, high water tables, or tight access locations.
Backed by CE certification and tested to BS EN12566-3/A1:2009, the Ensign:Ultra delivers industry-leading effluent results:
11.5:19.2:8.4 mg/l (BOD:Suspended Solids:Ammonia) — equating to 97% pollutant removal.
The Ultra model takes everything great about the standard Ensign and enhances it further — adding quieter operation, improved effluent quality, and the Polylok tertiary filter for even better protection of your drainage field.
Whether you’re a homeowner, developer, or installer, this is one of the best shallow dig options on the market — with no compromise on compliance or performance.
