How do bacteria help in a bio-digester?

We all use toilets every day, but have you ever thought about where the waste goes after you flush?

In cities, there are sewage pipes to take it away. But in villages or faraway places, that’s not always possible. That’s where a bio-digester system helps. It’s like a smart toilet that manages the waste smartly. Let's break down the steps.

Waste Goes into the Tank

When you use the toilet, all the human waste goes down into an underground tank. It’s called a bio-digester tank. It’s fully closed, so there’s no smell, no leakage, and no mess.

Bacteria do the cleaning

Inside the tank live tiny helpful bacteria called the innoculum, developed by DRDO. They eat the waste and break it down. No chemicals. No machines. Just nature doing its job.

What comes out

After a few days, the waste turns into Clear, odorless water that safely seeps into the earth, recharging groundwater levels.

That’s it! No dirty sludge, no smell, and no need to clean the tank for very many moons.

How is this useful?

These bio-digester toilets are great for schools, worksites, villages, and more. They help us keep the environment safe and our health, too; it's a win-win situation.
