Conventional water flush urinals use approximately 4 liters of water for flushing. This figure goes up to 10-15 liters when a toilet pan with flush is used for urinating. Water used for flushing urine increases the volume of sewage generated in cities. The use of hard water for flushing urine leads to scale formation that causes blockage in the drains. Dampness in urinals offers a favourable environment for microbes and air-borne infections. High nitrate and phosphorus levels are found in sewage which can be reduced if urine is separated from sewage for productive use such as agricultural and industrial purposes.

Waterless urinals do not require water for flushing and can be promoted at homes, institutions, and public places to save water, energy, and to harvest urine as a resource. The reduction in infrastructure required for water supply and wastewater treatment is also a spinoff arising from installing waterless urinals. The concept, founded on the principles of ecological sanitation, helps in preventing environmental damage caused by conventional flush sanitation systems. “Zerodor” does not require replaceable parts or consumables and can be fitted to most existing urinal pans. This results in very low maintenance costs as compared to other solutions in the market.

“Zerodor” is a proprietary technology of which IIT Delhi and Ekam Eco Solutions has acquired all rights to disseminate this technology widely nationally and internationally. As North American partner of Ekam Eco Solutions, SeLow is responsible for the production, optimization, and distribution of the Zerodor technology in North America. Governmental funding is currently being requested.
