Household Level Composting (Manure Pit)

At each household, two manure pits should be dug. The size of the pit will depend upon the quantity of refuse to be disposed of per day. Each day the garbage, cattle dung, straw, plant and agriculture wastes are dumped into the manure pit. When one pit is closed the other one is used. In 5 to 6 months time, the refuse is converted into manure, which can be used in the fields.

This is the most effective and simplest method of disposal of waste for the rural households. Cow dung can also be disposed of easily by this method. Mixing of cow dung slurry with the garbage will help greatly in converting the refuse into compost, which provides good manure.

Give a single layer of broken bricks at the bottom

Make a ridge with the help of mud at the periphery of the pit & compact it by light ramming.

Use and Maintenance of the Pit

Go on adding garbage from the house over the layer of bricks (only biodegradable type)

When the garbage attains a height of about 150 mm, add dung slurry, mix it with garbage & level it

Spread a very thin layer of soil over it (once a week) to avoid odour and fly nuisance

Continue to add garbage everyday

Follow the above procedure & repeat the layers till the pit is full. It is recommended to fill the pit up to about 300 mm above ground level

After 3-4 days the garbage above ground settles down

Plaster it with soil

Leave the pit as it is for 3-6 months for maturation

After 3-6 months take out the compost & use it in the fields

Till the manure in the pit matures, use another pit of the same dimensions, dug at a minimum distance of 1 m from the first pit.
