20,000 litre Wastewater Disposal - Solutions Required! Thane, Maharashtra

ISKCON Food Relief Foundation is implementing the Mid Day Meal Project of Govt of India. We are setting up a new kitchen at Wada, Thane Dist, Maharashtra. This kitchen will cater to about 50,000 school students. The premises are not connected to any drainage system. There is an open well with good water as the source of water supply.

Our waste water per day will be in the range of 20,000 litres, mainly from the washing of containers. Please suggest the best method for disposing it off. We are confused between Septic tank and Soak Pit. Please give details. Are ready to use varieties of techniques available to achieve the best possible result.

1. Waste water treatment & re-use.

Dear rkd_rns,

These are times of water scarcity which will get more acute as time goes on. Kindly consider treating and re-using the waste water after treatment,as this would reduce to that extent your useage of fresh water.The kind of waste water you generate is known as " grey water" and it can be treated and stored for uses like toilet flushing, gardening, washing of vehicles/roads or yards.

I can help you to source a grey water treatmen system if you are interested.

A septic tank is a tank into which water used to flush toilets is collected and gets treated in a natural anaerobic process by means of a bacterial process.A soak pit is a pit into which water treated by the septic tank is allowed to flow and then soak into the earth. Kindly make sure that the total waste water quantity mentioned by you is accurate.

Let me know if you need my help to get a suitable treatment plant for your waste water.

5. Treatment Plant

I would think that your best bet would be to try out a simple constructed wetlands system. If you need help to figure that one out, do let me know. best wishes and luck, Firdaus.

8. Waste water treatment & re-use

Dear rkd_rns,

Kitchen waste of 50000 students has a good potential to produce Bio-Gas. Part of your gas bill may be cut by using Bio-Gas. There are some people who can help you in putting Bio-Gas plant. The treatment required for effluent will be reduced.

Good luck!

11. Disposal of Kitchen Waste (Oil and Grease Trap)

Dear Sir,


RKD_RNS,


You are looking for treating Grey Water, Toilet waste, when your major issue will be disposing off Fat/Oil/Grease(FOG). 50,ooo meals/day, have you estimated amount of Fat/Oil/Grease(FOG) will be gererated by preparing these 50,000 meals/day? FOG is Long Chain Fatty, which is considered non bio-degradable and most difficult to get rid off naturally or thru chemical treatment. If you prepare Septic tank or Soak Pit, FOG will stop percolating soon and your whole project will go wrong. I thing you 1st required to treat kitchen waste than think of other thing.  


Please also visit http://www.indiawaterportal.org/node/17532 to know about FOG.


For further information please be in touch.


Thanking You,


Hiren Pancholi

14. Constructed wetlands

Dear Sir,

Best and Cheapest  option would be building a constructed wettland. In Constructed wettlands the plants take the Nutrients, give Oxygen to water and clean Water. The said water can be reused into Toilets or Swimming Pools. A further treatment may be required if reuse is required for Drinking or Cooking. 

Please Email me or Call me at 9948172755 if you are interested in wetlands. 

Thank You,

15. Would you share the links/documents of the work done with us

Mr.Prasad,

Interesting. Would you be able to share any links/documents of the implementation you may have carried out? I have some familiarity with this topic (currently taking an on-line course on this subject).

I believe this methodology offers very good solution, provided that certain prerequisites are met. I wonder if ISKON and you have explored this at any further level?

Thanks,
Arati

16. From your inputs, it looks as

From your inputs, it looks as if you want to know how to deal with the water outflow from the kitchen and not the kitchen waste (i.e. left over food, vegetable peels, spoil vegetables etc.).  Mr.Dilip Pandit’s  suggestion assumes the latter. If you want to generate gas from the latter, pl check on the web for the organisation “Andhyodaya” in Kerala which has developed simple system for this. If you want to know how to deal with the water used in the kitchen,  and if you have sparable soil space, I can advise you on a simple method to handle it.

17. Use bar-screen chamber to prevent bigger solids from coming in

Dear Mr. Das,

First you need to have a bar-screen chamber to prevent bigger solids from coming in and then a baffled grease trap to separate oil and grease. In this grease trap you may use our slow release tablets which contains bacteria that degrade oil and grease, soaps and detergents i.e it degrades the contaminants of grey water. The collected water from the grease trap may be chlorinated and re used filtered/ unfiltered or passed to soak pit.

You may contact me at 9910170604 for further discussion.

Thanks and regards,
Chandan

18. To build septic tank in individual house,Bangalore- Is it legal?

Can any one tell me if constructing a septic tank in an independent house in Bangalore is legal or illegal (BBMP jurisdiction).
We don't have government provided sewage line and the current one goes to wild - a common septic tank that has now been considered to be in illegal land owned by the railways.

If they are illegal, I would like to know which rule is that and how come the current one that we have is legal as well as the cases about all houses where common drainage system is not there.

If it is legal, I want to know how to build an environment friendly septic tank, if possible to combine with a rainwater harvesting system (including minimum distance from borewell, sump, building etc).

Any help is appreciated.

19. Please post your query here & our organization will get in touch

Dear Shri Radha Krishna Das

I just spoke with you about exploring further with you all at ISKON regarding your needs.

Please post your email here (I was not able to send you an email from the above) and we will pick up the conversation to see if our organization can be of service to your cause.

Thanks,
Arati
