Eco-Sanitation
Here Chat is "demonstrating" the new throne pedestal. A handful of saw dust or ash is used after each use. The result is a smell and fly free environment. The room to the left is the shower and the urinal. The cost of each latrine is approximately $900 each and has an unlimited lifespan.

What is Eco-Sanitation?


It is an environment friendly sustainable sanitation system which regards human waste as resource for agricultural purposes and food security. In contrast to the common practice of linear waste management which views waste or excreta as something that needs to be disposed, Eco-Sanitation seeks to close the loop of nutrients cycle, conserve water and our surrounding environment.

These toilets operate on the principle of keeping urine and feces separate during treatment. They sanitize faces through one or more of the following processes: desiccation (drying), increase in pH (more alkaline) or increase in temperature.

Basic principles of Eco-Sanitation Latrine:

1)Offers a safe sanitation solution that prevents disease and promotes health by successfully and hygienically removing pathogen-rich excreta from the immediate environment.

2)Environmentally sound as it doesn’t contaminate groundwater or save scarce water resources.

3)Recovers and recycles the nutrients from the excreta and thus creates a valuable resource to reduce the need for artificial fertilizers in agriculture
The plan that Start With One Kenya has adopted (slight modifications to th above plans) is a shower room/urinal room on one side, and a throne with urine diversion on the other. Urine can be collected and stored in a separate tank. After a couple of days it is completely sterile and may diluted with water in a ratio of between 1:10 and 1:5 and then applied to vegetation.

Feces are collected in a chamber located directly below the pedestal unit. After each use lime, soil or ash is sprinkled on the feces in the chamber (see photo alongside). This raises the pH and assists in the destruction of pathogens as well as preventing foul odors from escaping. Of the three main methods of killing pathogens - pH, reduced moisture & increased temperature - raising the pH is found to be the most effective. At a pH of 9 the feces are rendered safe and odorless after six months.
Most of these systems use double chambers. While one chamber is in use under the pedestal the second chamber is stored while the feces inside are desiccated. Once desiccated the faces are odorless, light in color and consist of large particles. They can be added directly to the soil or composted further to produce humus.

Start With One is committed to providing dignity to human life through this environmental friendly latrine. Currently, SWOK is concentrating this ministry to IDP (Internally Displaced Persons) Camps where there is no sanitation facility. You can help us in this project by donating toward the cost of these life-changing latrines. Each latrine costs approximately $900. Currently we have plans to build over 180 latrines in two IDP Camps.
