Rice on the roof - How to use grey water for growing paddy

A simple reed system can clean washing machine and bath water enough to grow rice. What better place to do than the roof which in tropical India receives a lot of sunlight. Nutrition for the rice comes from a Ecosan unit on the roof again, which provides the urine for fertilizer. Finally a solar box cooker cooks the rice for consumption.Food and water Cycle complete on the roof.The water for the washing machine and bath comes from harvested rain falling on the roof but a slightly different part.

Great idea! what about the urine from diseased persons

[zenrainman]

@kmraghu61 you have to be careful..and it depends on the disease. Generally at the family level it is not a problem...but care and precaution always.

[zenrainman]

Not really, the reeds pretty soon fill up the tank and there is no space for the water to be open for the mosquitoes to go in...

This system that you demonstated, shows a very effiencient use of waste water. I live in a cooler temporate climate with evergreen trees. Do you have any fruit trees? Do they get the biosand filtered urine? Is urine good for fruit trees?

[zenrainman]

Urine is also excellent for fruit trees since they have quite a nicely balanced N,P,K and micro nutrients. Apply in small doses and diluted 1:5 to begin with...

Can you grow rice in Southern California weather?

[beelzebubsaves]

@kmraghu61 the system is for "grey water", sewage is "black water"

[copefarms]

@kmraghu61 urine is sterile so is not a problem

@zenrainman thanks for uploading this video. I'd like to ask you how many kilos of rice you normally produce in that paddy per year?

@kmraghu61

If urin were to be bottled until it changed to ammonia, the pH with the ammonia would kill ANY bacteria, virus, pathagen ect...

[kmraghu61]

Great idea!
