    Dear Ms Chithra,

    Selection of plants depends on the salt tolerance of the plant. It is more important to assess the TDS and sodium content. Non-edible plants are preferred. Make sure that heavy metal and BOD are with in tolerance limits. However all plants common to the climate and soil can be irrigated.

    There are actually hundreds of plants that are used for bio-remediation of raw sewage. You can grow ANY plant with treated sewage provided the parameters after treatment meet Pollution norms.

    Hi Rajesh,

    As told by our friends, you can grow most of the vegetables with treated sewage. You might want to try addition of Magic-gro Plus, which is a researched biotech product for your plants.

    Thank you all. I am keen on gathering information on the species that can be cultivated with treated sewage, as we need to convince farmers to carryout cultivation utilising this treated sewage effluent. In many places, sewerage scheme has been taken and disposal of treated sewage is becoming difficult due to non-cooperation from agriculturists. Hence we plan to prepare a presentation/ live examples of how to reuse treated sewage in irrigation, how resourceful it is, etc...

    You can also use treated sewage to grow fish.

    You can build a fish pond and grow Diatom algae and these are good food for fish.

    Diatoms increase the oxygen level and thus prevent any foul odor from the treated sewage.

    The nutrients that remain in the treated sewage would be the source of food for Diatoms.

    The fish pond would be sort of tertiary treatment and the water will be much more clean after this process.

    Studies indicate that growing Cabbage, Cauliflower, Spinach ..etc using untreated sewage causes increase in heavy metal concentration..

    Most of the vegetables grows well in sewage and most prominent are Cabbage, Cauliflower, Tomatos etc. however, if you are intrested, i have an idea for generation of fertilizer from sewage. you can use this fertilizer of every plant.

     

    Thanks,
