Chapter 1


Throughout the developing world there are numerous problems that are constants: undrinkable water, pollution, inadequate nutritious food, and a myriad of pathogens and diseases.  This book will not be able to entirely solve all of these problems, but aims to vastly improve lives for those that embrace it by providing a solution for sanitation and nutrition.  If you build what’s called a “Urine-diverting dehydrating toilet”— UDDT for short— then you will embrace its benefits, namely that disease-causing pathogens from feces are eliminated and viable, nutritious fertilizer will be generated from what is discarded from the human body as waste.  This new source of fertilizer will produce more nutritious food for the family, help nourish the soil, and your water and soil will be cleaner.  This is done by eliminating the major source of contamination, feces.  Importing food, fertilizer, and antibiotics is only a temporary solution for your community.  Permanent solutions will only be achieved if the cause of the problem is eliminated.   I urge you to look for local solutions that will have long-term benefits.

A UDDT is simple to build and can be built from local material by local craftsmen. Use the information in chapter five to design your UDDT and solve your sanitation problem. Though the material can be substituted the design must be adhered to. It must be constructed above ground, be waterproof, and have 2 chambers. There must also be provisions to separate the urine from feces. 

There are many advantages to using a UDDT:

· It does not use any water. In fact the toilet must be built watertight so no water can enter. The collection chamber (vault) is also sealed at ground level so no feces can leak out and contaminate the water or ground. 

· There are no flies or odors. 

· It is suitable for all types of users and the only item that needs to be decided at time of construction is whether to install a toilet or a squat pan. 

· Once built the toilet will last forever, if maintained. 

· The UDDT will provide vast improvement in health

· It supplies fertilizer that is adequate to grow enough food for the family. Food grown is of a higher quality and any extra food can be sold thereby increasing the families’ income. 

· Women will no longer need to venture far from their house to use the facilities and fear attack or embarrassment. They will be safe in or near their home. The UDDT can even be attached to the house.

The chief disadvantage is that the toilet is a permanent structure so there are expenses in construction. The cost will vary depending on the location and local building material but the costs can be recouped by selling extra crops, selling the fertilizer, or saving on the cost of food, see construction material list. Microloans can be used to finance the construction. The generated fertilizer can be sold or used to grow crops to sell. Also, if the population is unfamiliar with a UDDT then they need to be educated to its advantages. If the people do not accept and use the UDDT then there are no advantages. 

The UDDT has the advantage of being adaptable to different communities. It can be constructed as a standalone facility, attached to the house, or incorporated into the home. You can use either a sitting or squatting toiler, and either anal wash or wipe.
