The Tank Guaranteed Not to Collapse When Empty*

* When installed in compliance with manufacturer's installation instructions


The new generation of Platin low-profile underground rainwater tanks makes installation easier than ever

The Platin® tank lineup consists of four low-profile tanks ranging from 400 gallons to 2,000 gallons. The ultra-high strength design of the Platin makes it groundwater stable up to the tank’s shoulder and, when fitted with the appropriate lid, is safe for vehicle traffic. The Platin tank is guaranteed not to collapse when empty when installed per the manufacturer’s specifications.

 

Platin Tank Features:

  • 15 Year manufacturer's warranty
  • Minimal installation depth
  • Suitable for vehicle loading (when combined with cast iron lid option)
  • Groundwater stable to the tank shoulder

Ease of installation:
