Product Description

The Water Lab toilet prototype is a stand-alone dry toilet. It has a polymer membrane inside its storage container that dries out the excreta and vaporizes the liquid so that waste volumes are reduced. No energy input, external storage, or water input is necessary. The toilet is targeted towards refugee camps in the first phase, but commercialization of the product to households and construction sites is planned for the future.

Market Suggested Retail Price

$350.00

Distributors / Implementing Organizations

The Waterless Toilet is currently a prototype but Water Labs plans to sell the product to NGOs and governmental agencies that will implement the product in emergency settings. They aim to provide waste management companies with toilets for their sanitation services. Water Labs intends to sell directly to end users as well.

Manufacturing/Building Method

Change: Water Labs is fundraising to secure the scale of manufacturing, and is developing partnerships with low-cost manufacturers in Asia.

Manufacturer Specified Performance Parameters

The toilet should reduce waste volume by 90-99%, reducing the necessary emptying frequency by 10-15 times, and increasing leveraging of existing waste collection by 2-3 times. This reduces the overall cost of sewage management by at least 30-50%. One square meter of the polymer material will vaporize 15-30 L/day (10-20 daily-person-equivalents) of liquid sewage, even in relatively high humidity.Interview with manufacturer
