Use of Treated Waste Water for Cultivation Through Hydroponics

Today, the world is suffering with food and water scarcity due to population explosion and unevenness in the climatic conditions. The world needs food which will satisfy its nutritional need and will be available at cheaper cost. One can grow the same in very small space. The world needs techniques which one can implement easily and without much of an investment.

Hydroponics is one of such technique. In hydroponics, plants are grown with the use of water and nutritional solution only. The nutritional solution contains the essential nutrients which are required for growth of the crops. The crops are artificially supported in the nutrient mixtures and made to grow using the nutrients provided only.

The water which we treat in our sewage treatment plants is mostly discharged into the drainages. But, as it was containing human excreta, it is rich in the N (nitrogen), P (phosphorous) and K (potassium). N, P, K are the macronutrients which are required for the growth of the plants. So, such water may be used by hydroponics system to grow the plants in the most economical manner.

This project tries to create opportunities for the people having arid land and small spaces to cultivate the crops for their daily need. The waste water generated can be used in this system to make it cost effective. This project tries to make the townships self-sustainable by creating an opportunity to grow the plants in small space by optimizing the resources. This may create a source of income to the townships and home owners.
