Lightweight for remote locations & faster installation

High density polyethylene (HDPE) Tank treatment units from Waterloo Biofilter are constructed of a very high strength, durable, and seamlessly blow-moulded high-density polyethylene tank.  HDPE Tanks are pre-plumbed at our factory, filled with the Waterloo Biofilter filtration medium, and shipped to site fully assembled.  Treated effluent is pumped from the HDPE Tank to a small, shallow soil disposal system.  HDPE Tanks operate in recirculation mode for increased nitrogen removal.  These units are lightweight for ease of transport, and come pre-assembled for an easy, ‘dig-and-drop’ installation.  The only moving parts are two high-quality, energy efficient 1/2 horsepower effluent pumps that operate intermittently throughout the day.

Benefits of the HDPE Tank Configuration:

• Ideal for small lots
• Ideal for increased nitrogen removal
• Lightweight tank is ideal for barging to islands & difficult access sites
• System is completely below-ground and out of sight
• HDPE Tanks are pre-assembled for a faster, easier installation
• Minimizes site disturbance
• Passive air vent fitted with activated charcoal filter to block potential odours

HDPE Tank Biofilter System Overview

No mounding or tree removal was required at this waterfront HDPE Tank Biofilter installation. An attractive rock garden hides the system access risers while still allowing for easy maintenance.
