Urine Diverting Toilet
Pu Ngaol Village
Solution
By utilising a urine-diverting toilet, the urine and faecal matter will be able to be easily seperated for seperate use.
Due to faecal matter being unable to be used on human-consumed crops, seperating the matter will allow for the urine to be used on seperate farming areas.
The Pu Ngaol village is a small community, with a land of about 3000 km2, with 54 ha being farmland, located in the Mondukirir Province of Cambodia. It has a population of 547 people, 108 houses. They pride themselves in the agricultural industry, where 90% of all labourers work on farms. Due to their agricultural focus they spend a lot of money on fertilisers for their crops (over $10,000).
Problem
By creating a new toilet facility, the villagers will be able to utilise their waste on crops to minimise the costs spent on fertilisers.
Due to the high costs in agriculture, they have limited money left to spend on other areas.
Due to the lack of toilets many villagers practice open defecation, leaving faecal matter left in the ground.
