Klargester Gamma Rainwater Harvester 4600L
£2,852.00
Direct Drainage Reviews

An intelligent, shallow dig tank rainwater harvesting tank solution, the Klargester Gamma is developed to provide the homeowner with a system to ensure an automatic supply of harvested rainwater for the home or garden. With a technologically advanced finish the Klargester Gamma is a suitable for both self build projects and residential developments. It works by taking the rain from your roof gutters, filtering out leaves and debris and storing the water in an underground tank.

Which system is for me?


The Gamma system has two primary options:

  1. The Gravity System which uses an elevated header tank to store filtered water after the main tank.

  2. The Direct System which pumps water from the main storage tank and is used where a header tank is impractical.
