Installation is Easy
Just choose the system that's right for you!

Envirolet® is a composting or biological toilet system that evaporates water and breaks down waste by natural bacterial action. This patented toilet system accelerates the decomposition process and converts waste material into a natural soil residue. Envirolet™ is easy to install. The many features offered with Envirolet™ make the toilet system easy to operate.

Proper installation and operation is necessary to ensure that your Envirolet® toilet system will function properly.

Your Envirolet® will arrive completely assembled and ready for installation. Envirolet® offers simple, easy to understand, do-it-yourself instructions. All materials are included for standard installations (some additional, low cost, rigid ABS vent pipe is required for Remote Systems). Your vent kit simply installs above the roof and a 4" Wind Turbine or a Special Ventilator attaches to the top.

Please call toll-free (9am - 4pm EST, Monday - Friday) if you have any questions about installing your Envirolet® System to ensure proper installation:

  • Canada Toll-Free: 1-800-387-5245
  • Toronto: 416-299-4818

  • Vents should be installed either vertically (i.e., straight-up) through the roof (highly recommended for Non-Electric Systems to improve aeration and drafting), or horizontally through a wall, or below a floor and then upwards with vent angles not exceeding 45 degrees each. Insulation around exposed vents is recommended if cold weather is a factor. All Remote Systems come with flexible drain and vent duct pipes that easily connect or disconnect.

    REMOTE SYSTEMS install either on the ground outside, or in the basement, and some Systems come with a special Filter Drain. Waterless 110v Electric models do not include a Filter Drain as standard equipment, but this is available as an option if extra capacity is required.

    Envirolet® Low Water Remote Systems
    are installed with a special Filter Drain. Though most liquid is evaporated by the Automatic 6-Way Aeration™ System, periodically a minimal amount of excess liquid may drain from the System, and the drain must gravity connect to an approved leaching pit, septic tank or holding tank. Check local regulations regarding draining when installing your System.
