Colour coding of Handpumps

During the process of awareness creation amongst school children, I learnt from a student that there exists a YELLOW COLORED hand-pump in their locality (in Bangalore) which is not used as a regular source of water. During the two days of water problem in Bangalore residents of that locality used that water for drinking and cooking purposes and as a result faced digestive problems.

This raised a curiosity in me to trace out the reason behind YELLOW COLOR coding of that particular hand pump.

I tried searching for the same in websites and found that RED COLORED hand pumps indicate ARSENIC contamination in the aquifer.

In this regard, I would like your guidance regarding the COLOR CODING GUIDELINES available in India and the source from which I can get the detailed information.

Also please let me know the government authority handling the same.

1. colour coding

Dear Shilpa S,

There is no specific colour coding that is being used in india, which they have evolved which can be universialy applied everywhere. Like you have mentioned Blue and red codes for safe water and arsenic contamination( unsafe water)

This is due to the fact that water resources especially Groundwater comes under the preview of the state goverment and there is really no central legislation in place. The state level legislations are  also more  theoritical  and really not something that can be pratically implemented properly. They have been just compiled by taking in to considration other legislations in place in some of the developed countries, and no considration to the kind of data available or the existing limitations and  ground conditions in our country.

However there is a general code for water quality and is based on the kind and degree of contamination found in waters, Here again Blue is for clean drinkable water, and where yellow is for higher levels of nitrates.( source of which coudl be or chemical nature or human contamination)

It would be ideal , if you approach the local goverment body incharge of installation of handpumps and ask them what is the basis of colour code they have really adapted.

Hope you find the answeres you are looking for

Best of Luck

2. reg. color coding

Dear Sir,

 

I initially thank you for your immediate response and also for focussing on the negligence involved in framing the legislations re;ated to groundwater.

I would like to know the reference source from where I can find out more information on the "general code for water quality" which you have mentioned in your comment.

Also, in regard to the "local goverment body incharge of installation of handpumps", there's a lot of ambiguity in case of Bangalore city as it falls under three authorities - BBMP, BWSSB, Groundwater board.

So, I am unclear on whom to approach for the information I seek.

I would agin request you to provide some clarity in this regard.

3. Dear Shilpa S, Generally in

Dear Shilpa S,


Generally in practice, the following three colours are used for colouring the handpumps.
• Red Colour-water having chemical contamination and not fit for drinking purposes.
• Yellow Colour:-Although water is fit for drinking but the availablity is only during winter and rainy season.
• Green Colour:-water is fit for drinking and is available throughout the year.

Dear Shilpa S,


As per ongoing practice in PHED, Assam generally when we are confirmed existence of  toxic contaminants, like Arsenic and Fluoride in an area, we test all sources and paint the spout with red colour, if contamination is above permissible limit. All other hand pumps are painted with blue colour, if safe for drinking. People in the vicinity of the Hand pumps are made aware of the fact that water from pumps painted red, is not safe for drinking. A signboard in local language is also placed near the pump, if painted red.

7. Colour coding of hand pumps

Dear Shilpa,


I learnt from your query that there exists a yellow coloured hand-pump in Bangalore from which local people have to draw water for drinking and cooking in the absence of any other source of water only to face digestive problems. As Project Engineer of a Bangalore-based NGO, you could easily verify yourself the existence of such a hand pump.


Use of coloured traffic signals in regulating traffic at road junctions has become so popular all over the world that motorists understand what to do. The same is not true with wells fitted with hand pumps. If such a hand pump exists, it would be better to display a board stating that the water from it should be used only for washing purposes, but not for drinking and cooking.   


Best wishes,

8. Response to Dr. R. Jagadiswara Rao

Dear Sir,

I highly value your suggestion of tracing the borewell and getting it tested for all the water quality parameters.

It was also my initial thought immediately after the issue was raised before me.

I discussed with my seniors at office regarding the possibility of the same and when I was not able to get a positive nod for the same, I opted this route of getting the help of other NGO's who are working in the area of water quality to go ahead with analysis of the handpump water quality.

 

Hence I chose this platform to reach out for NGO's and other experts working in water sector.

Dear Shilpa,


As per my knowledge there is no such colour code has been prescribed by any Government agency for water sources.However, indications regarding Potability of water is being mentioned in many states by colouring them or by written instructions.

Dear Shilpa S,


I have searched but could not find such guidelines from an Indian organisation/authority such as BIS. What I did find clearly was from the Occupational Health and Safety Act (OSHA) in USA. Similarly, ANSI also has guidelines for colour coding.The following are from OSHA:
RED- The basic colour for the identification of fire protection equipment & apparatus such as fire buckets & and pails, fire extinguishers, fire hydrants and fire pumps.
YELLOW- The basic colour for designation of caution and possibly hazardous conditions.
I would recommend that you should take a look at OSHA and ANSI standards for such colour codes. Such information may also be available in India and a google search would find this information.

Dear Sir,

 

As per your advise I shall refer back to the ANSI and OSHA guidelines.

Do let me know if you come across any Indian Guidelines regarding the same.

There is no such practice used in Haryana.

Dear Shilpa,

Thanks for the query. Unfortunately, there are no guidelines for colour coding of handpumps in India.

It depends solely on the discretion of the project proponent and/or the research organisation performing research in a water quality affected area.

But certain rules of thumb do exist, which is shared with the community so that everybody is on board.

I am attaching 3 case studies for your information.

Hope you will find them to be useful.

Best,

Ayan
