Sur la base de quel critère/indicateur(s) (sans relation avec la stratégie) la pratique proposée et technologie correspondante ont-elles été considérées comme « meilleures »?

This technology prevents pollution of ground and surface water from human and animal biological waste; it saves significant amount of water with drinking water quality from being wasted by flushing this water into the toilets.

Principaux problèmes abordés par la meilleure pratique

Pollution of ground and surface water; water borne diseases; decreased annual rainfall; increased annual temperature; unwise use of scarce water resources.

Décrivez les principaux problèmes liés à la dégradation des terres abordés par la meilleure pratique

Safely treated biological waste (by composting, vermicomposting or appropriate storage) is used to improve soil fertility and strive erosion of degradated crop lands due to overusage.|

Précisez les objectifs de la meilleure pratique

Prevention of waste of water of highest quality by flushing it in the toilets; prevention of water pollution by biological waste; prevention of water-borne diseases; creation of better livelihoods consuming less water resources.

Brève description des principales activités, par objectif

Scarcity of water is fundamental reason for water-borne diseases; it is also a reason for worse hygienic practices. By saving water of high quality from wasting and preventing water pollution, we improve health conditions to people.|
Storage of biological waste in way that it never gets in contact with ground or surface water bodies; safe treatment and safe application in agriculture.
Promotion of waterless ecosan toilets with separate collection of urine and feces; separate treatment and re-use in agriculture.
Training of population, youth, experts for construction and maintenance of the constructed toilets, filters and wetlands is crucial for the sustainability of the projects.|

Brève description et caractéristiques techniques de la technologie

Waterless toilets are toilets that does not use water for flushing, but use absorbent (saw dust, ash, etc.) to cover the fresh feces. Urine and feces are stored and treated separately to the level of sterilization. Then used in agriculture as natural fertilizer (urine) and soil conditioner (composted feces). The final step is to apply these treated products in crop land.|
The technology is based on separation and separate treatment and reuse of urine and feces; waterless urinals; reuse for agriculture; composting.

Less consumption of water offers better potential for the downstream users to meet their needs.
Prevention of pollution of water resources offers better potential for the downstream users to have access to water of higher quality and prevents water-borne diseases.

Impact sur la biodiversité et le changement climatique

Décrivez:

Prevention of biological pollution of water resources and decreased water consumption for household needs is very beneficial for biodiversity in and around water bosies; it prevents pollution with phosphorous and nitrification of natural waters.
Wastewater treatment facilities in their conventional technologies are a large source of pollution with greenhouse gasses; the proposed technology eliminates greenhouse production in the process of storage, treatment and use of metabolitic human and animal wastes.|
In the area we apply the technology all climate change models emphasis on increased water scarcity: the techlogy we promote does not use water; it saves water of highest drinking quality; it prevents pollution of natural water bodies.

Liées aux ressources humaines

There is no experts trained in sustainable sanitation to open chance for scaling-up; the engineers are not trained in sustainable sanitation technologies.

Liées aux aspects financiers

There are no targeted financial mechanisms in the country to encourage application of alternative sustainable sanitation technologies.

Liées aux aspects techniques

Sustainable sanitation does not follow the pattern one size fits all; there is broad variety of technologies that will best fit any specific demand or environment.
