There are alternatives to conventional RCC STPs. The Root Zone Wastewater Treatment system utilizes nature’s way of biologically processing domestic & industrial effluents. This effective technology called Decentralized Wastewater Systems (DEWATS) was developed in 1970s in Germany and has been successfully implemented in different countries mainly in Europe & America.
Such STP unique patented technology treats sewage in a decentralized, self- sustainable way, in underground chambers without power, chemicals or human intervention. Using Biomimicry, regenerative innovation inspired by nature. DEWATS utilizes functional principles and strategies of microorganisms and ecosystem found in a cow’s stomach. The biologized method converts “bad” water to “good” water using the same ruminant stomach process. The solution can treat waste ranging from 3 KLD to 1 MLD.
​
DEWATS STP runs on zero power, requires very low maintenance. Most importantly, it’s running cost is 85 % cheaper. Unlike a conventional STP, it does not need a motor, exhaust fans, pumps and labour.

The city of Bangalore generates 5,000 metric tonnes of waste per day, of which about 60% is said to be wet waste. About 3,500 tonnes of waste is mixed. Dry waste also tends to lose its economic value, making it almost impossible to recycle. A large chunk of mixed waste ends up in landfills (Per Economic Times May 14, 2019). There are recommendations by KSPCB (Karnataka State Pollution Control Board) for mixed waste collection and more robust policy level changes. Meanwhile, there are several companies are doing pathbreaking work in the sector of WET and DRY waste collection and recycling.
The efforts of these well known waste management companies prevent a whopping 25 tonnes of waste from reaching landfills on a daily basis!
VIKASIT Ecosystems "FLAGSHIP SOIL MAKER", composts 100KG of organic waste to compost in just 8 hours, with minimum consumption of electricity. Their tech is a game changer in the composting game, and will be of great use to larger organizations looking for effective waste management methods.
