Benefits of ecosan systems include:
* Minimizing the introduction of pathogens from human excreta into the water cycle (groundwater and surface water) - for example groundwater pollution by pit latrines.  
* Conservation of resources through lower water consumption, substitution of mineral fertilizer and minimization of water pollution.
*  Less reliance on mined phosphorus and other non-renewable resources for fertilizer production.
* Reduced consumption of energy in fertilizer production: Urea is a major component of urine, yet we produce vast quantities of urea by using fossil fuels. By properly managing urine, treatment costs as well as fertilizer costs can be reduced.
