Marsh Portapura Sewage Treatment Plant 2-5PE

from £2,835.00

Marsh Portapura Sewage Treatment Plant

The Marsh Portapura is a compact, portable sewage treatment plant designed for single properties, holiday homes, and small commercial or temporary sites. Manufactured by Marsh Industries, it's CE approved to BS EN12566, treating wastewater to an ammonia level around 25 times better than the recommended standard. Waste settles in a primary chamber, then passes through an aeration chamber with diffused air treatment, before a final filter stage ahead of discharge to a watercourse.

Size & options

Available in three sizes, 2, 3 or 5 person units, with gravity or pumped outlet. Neck extensions are available for deeper installations. Can be installed above or below ground, and below-ground installation can be achieved in around 2 hours.

Key features

  • Low running costs – near-silent compressor with electrical consumption of just 1.8kWh/day, roughly the same as a lightbulb

  • Easy installation – lightweight, portable construction with no heavy plant required; can be removed and stored when not in use

  • Quiet by design – Whisspurr acoustic vibration reduction (AVR) unit fitted as standard

  • Outstanding treatment performance – 14:19:0.7 mg/ltr (BOD:suspended solids:ammonia)

  • Durable build – tested for fire resistance and structural integrity to EN ISO standards

  • Access covers available in brown or green to suit the surroundings
