Marsh:ENCO Sewage Treatment Plant 6-16PE

from £1,675.00

Marsh Enco Sewage Treatment Plant

The Marsh Enco is a cost-effective sewage treatment plant, built on the reputation of the Marsh Ensign range but designed for projects where competitive pricing matters most. Manufactured by Marsh Industries, one of the UK's leading names in off-mains wastewater treatment, it's tested and approved to BS EN12566-3/A1:2009, treating wastewater well within national consent standards. Waste settles in a primary chamber before passing into an aeration chamber, where diffused air and bio-media complete treatment ahead of discharge to a drainage field or watercourse.

Size & options

Available from 6PE to 16PE. Choose internal or external compressor housing — external is recommended for a longer compressor life, and supplied as standard on shallow and pumped outlet versions.

Key features

  • Low running costs – near-silent, low-energy compressor for minimal running, maintenance and servicing costs

  • Easy installation – optional risers available for deeper inverts; optional pumped outlets available

  • Minimal maintenance – removable PVC pressure pipe/diffuser for easy cleaning; 32mm sludge return resists blockages

  • High-spec bio-media (310m³ per m²) with membrane diffusers for even circulation, retained by securing mesh

  • Standard impermeable lid that blends into the surroundings while standing up to daily wear

  • Integral lifting eyes and stabilising feet for safe handling and transport

  • Unique 'keying-in' lip for secure anchoring into granular or concrete surrounds
