(Here are memorable excerpts from the meeting of TechTalk #6)


“This is about bringing joy to those who consume contaminated water -- with safe drinking water, thanks to the wonderful miracle of chlorine. For a century we have had this miracle treatment. Rodney Harrington is among the world's most knowledgeable persons in this domain. And he has a solution that is both economical and long-term, as well as available to individuals in all parts of the world at any time. I learned through Engineers Without Borders, about his solutions. Many believe that water shortage will lead to future warfare. In reality, by bringing water to areas where people are suffering, as well as offering education and leadership training, they are creating a source of peace. They've given the Global Water Works community the gift of leadership training. Anyone can get it. Today's session is the second of a three-part series on ‘Delivering end-use water’. Because there are over 2.2 billion people worldwide who suffer from water sanitation and hygiene issues, we need safe, clean water to reach people in every area across the world.”

-  Mary Eggert.


“Now that I'm so invigorated by witnessing so much work going on in the realm of solutions I must say that across my life, through my PhD and Master's programmes, as well as my whole research life, we have focused on recognising and diagnosing difficulties, mapping problems, and so on. We were able to contribute a little to solutions in the prediction and data arena, which earned us an honour. However, this is insufficient. I'm always thinking about all the different solutions, aquas, and waters, and so on. I felt invigorated and focused listening to the stalwarts speaking today. I want to be a part of the solution movements and be available and useful in this environment.”

-  Indrani Pal.


“Aqua Research is a for-profit firm whose objective is to improve the usage and supply of chlorine in poor and middle-income nations by providing on-site chlorine generators that are economical, dependable, and simple to operate. We've been developing, testing, upgrading, and marketing an innovative range of chlorine generators for use in healthcare, water utility services, community development, disaster preparedness, and disaster relief since 2015. Our goods are presently used in more than 20 countries worldwide. Field tests have shown their dependability, convenience, and cost-effectiveness; chlorine generated on-site costs substantially less than chlorine purchased from local vendors, saving an average of more than 200 percent per litre. Through our excellent collaborations with many worldwide nongovernmental relief and development groups that are showing how effectively our goods function, we are at a key juncture to accelerate sales and are ready for growth.”

-  Rodney Harrington.


“Rodney's technique ensures a constant concentration of 0.5 percent chlorine. People dislike the flavour when the dose is increased. It's a waste of chlorine if it's reduced. So having a system that delivers that much chlorine and disinfects the water on a constant basis is critical. We can place a filter system in front of these systems and then apply chlorination, like we do now. We installed a filter system and then utilised chlorination because the borewell water was quite turbid. In a school, they had a community of 500 children. They used to get sick a lot, but now they have clean water. These things can be accomplished. Local issues necessitate local solutions. Rodney and his team are exactly the type of innovators we need in India. Rodney has put together a team of professionals with both entrepreneurial and foundation expertise to understand where financing originates from. This is intriguing because I've never seen a team that can get into where the money is and get it to the folks who need it the most.”

-  Raj Rajaram, Doyen of Water Management, Chicago.


“For many years, chlorine has been the miracle disinfectant that has saved many lives. Many localities in India, such as municipal corporations, use just chlorine, but in a different form. Some use liquid chlorine, gaseous chlorine, or solid chlorine or bleaching powder. However, chlorine is the primary disinfectant used in communities' public water supplies. I could only find items for houses; there is no such thing as a water treatment product. Chlorine, on the other hand, is incapable of completing the task on its own. Sediment filtration is required, followed by carbon filtration, and a disinfectant should be present.”

-  TNVV Rao.



The picture here is a machine that I have at home for ‘water out of air’, Says Mrs Girija comember from Waste 2 Wealth. She adds: “Keep your windows open when you operate. The machine sucks oxygen from the room. I have been using this for the last 3 years. It gives about 20 lit. Of water per day. Very simple operation and quite helpful.

Air2Water systems work well in high humidity areas... Also it's technically recommended to keep outside the building for good efficiency... If kept indoor internal air becomes dry if there is no good ventilation

-  Murali Anur, WOW Executive Group


This is what is called in industry a ‘dehumidifier’, which is used to remove atmospheric moisture from an environment where absolute dry conditions are required for certain processes.

Pledge to make Bengaluru the best city Mr.Syed Khaja, Senior Environment Officer, Karnataka Pollution Control Board. I had an exposure to the proceedings of yesterday’s meeting through WOW. All appreciation for your initiatives on Water USE & REUSE. Making WOW a part of the Committee to be set up on Water is a welcome measure. Our Ganesh Shanbagh & Vikas Brahmavar, under the aegis of Dr.Hariharan, have great potential to work for any Water-related cause. May I request you to have the following points also in your future agenda which already found place in earlier WOW forum : 1) Detailed discussion of Point-by-Point analysis carried out on KSPCB STP Guidelines by WOW, which     will be sent to you by WOW shortly 2) Flood water Harvesting: In Delhi they have carried out this under flyovers and other public places     which I saw 15 years ago. Centre for Science & Environment, Delhi conducted this visit during their     RWH Workshop then which I attended.

-  U V Sitapati Rao, WOW Member Dear Shri Rao


We will share the draft proceedings. Please include your points also if we have missed anything. Let’s PLEDGE to make Bengaluru the *BEST CITY*

Groundwater recharge

This is a crude system of groundwater recharging but is effective. This simple system draws non-potable water for agricultural purposes in summer and reverses the process during the rainy season by recharging ground water. If every village adopts this method I think our ground water table can be maintained

-  Shivanand G Prabhu, WOW Member


Wettest years in Bangalore

Many more years to follow and floods too, until government servants go building after building to ensure rain water seeps to earth.

-  Neel Mathews, WOW Executive Group


Thanks. Very interesting discussion at WOW 23 Action Forum Meeting. Congratulations Suhail, Vikas,Ganesh and the team.

Use resources to such an extent that they cannot be reused further- has been the focus of my family Citizens of Bangalore can recall those days in the past, when normal life in the city was disrupted due to a water dispute with the neighbouring state of Tamil Nadu. The cause of this unrest was WATER. Such fights amongst citizens were also reported in quite a number of states too sometime back. It is important to realise that less than 1% of water on the planet is available for sustenance of our life, even though 75% of the planet is covered by water. Access to this 1% water is also becoming increasingly difficult. We all know that water is an indispensable commodity of our everyday life. However, we still continue to take supply of water for granted & use it with reckless abandon. This could be due to the fact that this a very precious commodity is made available to us at an extremely subsidised cost. No wonder that every one takes this precious resource for granted! It becomes very conspicuous by its absence. We citizens and consumers need to realise the importance of water conservation – and where best to start than in our own homes ?! I am going to share with you a few simple measures that I have implemented in my own home. I thank my wife, Arti, & son, Navneet, for giving full support in implementing these.

A couple of years ago, BBC and the NIT| Aayog, in separate reports, had made a grim prognosis for Bengaluru. The city would run out of groundwater by 2020. Bengaluru was listed as one among the 11 cities in the world to run out of groundwater. The list released by NITI Aayog was part of the Composite Water Management Index: A Tool for Water Management 2017. Now that we've reached 2020, what is the situation that we are currently in? Have we run out of water, or are we close?


We spoke to experts in the field to get to the brass tacks. Dr Hit Unnikrishnan, former Assistant Professor at the TransDisciplinary University, and a postdoctoral research associate at Aim Premji University whose doctoral research focused on the histories of urban water commons within Bengaluru and Dr Kshithij Urs, former executive director of the Greenpeace India who is currently an adjunct professor at the National Law School of India, Bengaluru.

"Bangalore has gone from being the city of lakes to the city of concrete. Because of this, all the water has disappeared." Years of rapid urbanisation, a swelling population and poor water management have led to drying taps, falling groundwater levels and filth-frothed lakes that can burst into flames. Bengaluru is paying a heavy price for its success since marketing itself as a tech hub in the late 1990s and attracting top firms including Microsoft, IBM, Dell and Google.


While job opportunities have soared in the sprawling city, millions have no piped water and instead rely on an army of privately-run tankers that suck water from wells inside and outside the city and deliver it to homes. Other families dig unauthorised private wells in search of water for drinking, bathing, laundry and other daily needs.


The WOW Action Forum hosts Commendation Awards every quarter and bestows the                                                                          on all Big Water-Savers who save and so ‘donate’ water to the city by consuming less fresh water in the interest of making water-positive cities.



Alt. Tech Foundation is a not-for-profit, for-industry Foundation for

(i) producing sustainability managers and leaders,
(ii) providing green management skill sets,

(iii) hosting city-wide campaigns for citizen collective action to save water & energy,

(iv) purposing research for city infrastructure.

WOW Action Forum is a globally pioneering effort for bringing collective private action to save very large quantities of water at apartments, at Industry, at tech parks, or hotels and hospitals or malls and other such buildings. The 2021 mission is set to save 1000 Cr lites with community-led action. This alone will bring a saving of 236 Cr in electricity bills for the city, and a reduction in carbon emission of nearly 300,000 tonnes equivalent.
