It is not unknown that 70% of the world’s water is untreated. This leads to much bigger problems. The communities without sewer systems are not the only ones that suffer, their neighboring communities also suffer from the contaminated groundwater leaking from the cesspits.
Villagers in Umm Batin, a Bedouin village in Israel’s Negev desert lack the shekels needed to build a modern sewer system, this in turn affects the neighboring communities. To combat this problem, Clive Lipchin from Israel’s Arava Institution for Environmental studies has developed a portable, cost-effective solution: a solar powered, self-operating waste-water mini treatment plant that does not need to be connected to the national sewer system.
In Lipchin’s system, the wastewater flows from household toilets, kitchens and sinks into a septic tank from where it is pumped into a series of treatment containers. Inside those containers, bacteria, fungi and algae remove the contaminants. The resulting treated water is not fit for drinking but can be used safely for agriculture.
The system works 24/7 and it stores it’s solar-generated power in a battery. The mini plant operates autonomously and it is managed remotely by a mobile application. If there’s any problem, the operator receives and alert and can tend to it immediately.
