Project Updates for GCIL 2020 Team Biome

On a typical Thursday, we head out as a team for some field work: whether it be a lake, to schools, to Cubbon Park, or to visit another place around Bangalore which Biome has impacted. Due to the strike today, however, Uber Ola were down, so we took advantage of having a full day to work on both our Biome project and our GCIL project.

We also chose to split up what we were working on today. While we are all sitting together, so that we could bounce ideas and source opinions from each other, Eric and I focused on typing up the Cubbon Park Well Report, while Kayla and Tessa began research for our GCIL project.

The Biome project, which is the report, is the one which we have been focused on in both these blogs and in our activities for the week. Now that we have most of our data collected, we were able to begin typing up the who, what, when, and why of the work we have been doing. Using the previous reports on Cubbon park, as well as doing research into infiltration and evaporation data around Bangalore, we were able to predict the impact that the 73 wells would have in recharging the aquifers. We had the time to sit down and analyze the data we had collected this week, looking at topographical elevations and analyzing the effect of the different types of soils in the area. For myself, it was a real life application of what I had learned in my Physical Hydrology class that I took last quarter, an opportunity to take the engineering I've learned and apply it to a solution which has changed how Cubbon Park is operated. With the addition of these recharge wells to work with the open wells, Cubbon Park has stopped buying BWSSB water, instead relying on the stored rainwater that exists across the park.

When we haven't been working for Biome, we have been developing a project for our program. This project has certain requirements: it must be an innovation or product which does not yet exist, it must be presented as a business model, and it must attempt to solve a grand challenge here in India. In brainstorming for this project, we wanted to make sure that we came up with something that would outlast out time here in India - something which Biome or another such organization would want to be involved in and continue even after we left. We also wanted it to be in connection with the water crisis here in Bangalore - for me, it is what I studied, but for all of us, water is something we never have to think of in Seattle. In Washington State, we have an abundance of water, the exact opposite of the water deficit that exists here. We wanted to try and push ourselves to first understand why this was an issue, and then find a solution or a partial solution.

When we visited the ten schools in Devenahalli, we noticed a few things. One, is that only a few rainwater harvesting and water treatment options were used; most only basic filtration systems, two had reverse osmosis systems, and one had a UV treatment system. Our next observation, however, was that these systems were not being used properly, and not being used to their full potential. Neither of the two RO systems we saw were being used as drinking water, which, as we know, is a big problem in rural Bangalore, as many schools have to buy privatized tanker water, which is pulled from wells around the city. One of the RO systems was broken, as was the UV system at another school. Each school had repairs which needed to be done, many of which still existed from the last follow up visit, meaning that the filtration systems hadn't been working correctly for some time. Our final observation was that the teachers and headmasters of this school did not seem to know much about the water conservation and storage that was taking place at their schools.

We initially wanted to focus on the misuse of systems and the potential of the upgrading the systems in place. There are so many easy, accessible, and affordable options for drinking water treatment, and we wanted to create something that could be easily added to rainwater harvesting systems in schools so that they would not have to pay for privatized water. Upon talking to our professors, and our TA Bujin, who worked with Biome last year, we quickly realized that we were focusing on the wrong problem: the issue was not that people were not using available systems, but that they were afraid of using them and did not understand the ones that were in place. The true problems lies in the lack of education that these teachers and headmasters have about the water crisis and the tools they have to help combat it.

We then pivoted, changing out focus to introducing an educational aspect to rainwater harvesting and water treatment in schools. Biome funds the systems that are put in place at these schools through donors - wouldn't they want the systems they put time, money and effort into to work properly and be used well after they are installed? How could we create a product that worked with the existing resources, while appealing enough to the teachers and headmasters so that they would be willing to become educated on these technologies?

Our project is an educational curriculum which will a prerequisite to receiving the funding and building of a rainwater or water treatment system from Biome or another such organization. By presenting this as a condition to receiving the system, teachers and headmaster will be pushed to be educated and knowledgeable about what will be put in place at their schools. This specific method of delivery was pointed out to us by Uma and Shubha at Biome today when we called them, because as they explained, teachers and staff are already extremely busy, and unlikely to take on more work if it is not presented as a job which needs to be done in order to receive something. By learning about the different options that exist, it will give the teachers and headmasters more control and power over which options would work best for their schools, which they know better than any of us or anyone from an organization who has only done a few site visits. This curriculum will present the benefits, drawbacks, potential, instillation, and maintenance for different options for non-potable rainwater harvesting systems, such as the basic filtration systems or ceramic filters, but also provide information on reverse osmosis systems, silver tablets, and combinations of potable and non-potable technologies. The teachers will then be able to work with the organizations and donors to tailor the system to best suit the school and students's needs, which will further motivate them to ensure that the system keeps working and provides the water they know it can. We want to build a program which shows a greater return on investment for the people who are putting time and money into this, but also cultivate more active and educated beneficiaries, this way the biggest difference can be made in the water quantity, and quality, at the schools.

Education is known to be a key component in solving any challenge. While our solution may not be solving the entirety of the problem that is water in Bangalore and India, by starting to educate the people who are hardest hit by it, we can hope for a spread of awareness which reaches multiple audiences. With both the well project in Cubbon Park, which we will be building educational posters to help park-goers understand the meaning of the work done there, and with the curriculum we are putting forward, we are trying to do our part in making sure that Bangalore has a sustainable water future.

Finishing up Cubbon Park Measurements

Today, in our final day (hopefully) of actual data collection around Cubbon Park, we measured the depth of the wells, as well as the level of water and silt in nine of the wells (to get a general representation of the distribution of water across the park). We also viewed the three lakes around Cubbon Park, but due to the language barrier we could not get enough information about the work that was done, and plan to return Friday with a translator to learn more.

The wells we measured were 2, 9, 14, 15, 16, 17, 23, 39, 54. We chose to take measurements of wells all over the park, but also of a few close together to see if we could establish a pattern. The depth of all of the wells ranged from 14-almost 16 ft; respectively, they were 15, 14.42, 14.25, 15.67, 14.75, 14, 14, 14.92, 15.1 ft. The water level varied; respectively again, the levels in inches were: 0, 87, 69, 82, 24, 21.5, 6, 64, and 0. Clearly, there is no clear pattern, and geographically there does not seem to be a relationship with water level. Wells 14, 15, 16, and 17 were very close to each other physically, but had water levels that ranged from 21.5 inches to 87 inches. They also did not have similar water compositions: well 16 had no silt and clear water, while well 14 had mixed silt at the water level. The other wells in this area had minimum silt. There were two wells, however, which did have silt. Well 9 had chunky silt up the 87 inches of water it had, and well 39 had heavy silt up to three inches and then mixed silt up to the top of the water. Skipping ahead slightly in the day because it is related to this, we had a call with Shubha and Uma where they recommended that we take a look at the topography (such as contour lines) of Cubbon Park to see if our measurements line up with what is expected. This will be our next step in our analysis for our report to Biome, since there was such a great range in water heights.

This day was different than all of our other days in Cubbon Park, because it was much more technical and analytical. Due to a strike on Thursday, we will be confined to the UTC campus, and will therefore take the day to complete the full report on the wells, which we will then add the lake information to.

Well Hunting Day Three

On our third and final day of mapping and locating the wells, we met up with another man from FAI. Like Manjunath, he knew exactly where the wells are, and (spoiler alert) we were able to get through the remaining 43 three wells all in one day. We did not get interrupted today, which meant we moved quickly through the remaining sections of the park quickly and efficiently. I've attached a screenshot of the completed map of the wells throughout Cubbon Park, as well as a picture of Tessa painting our very last well!!

We had time to discuss and reflect on this entire assignment as a whole while walking between wells. We quickly got to the conclusion that using resources provided by our program or Biome is always the best option, because we are strangers in this city still, and these projects are way over our heads. We also discussed what we learned, and debated about the placement of the wells around the park. Mr. Vishwanath, the founder of Biome, had mentioned that recharge wells have different depths and locations depending on where the aquifer is underneath them, and so we kept this in mind as we saw groupings of wells very close together. It is also related to the depth of the wells, because this relates to the depth of the aquifers or the groundwater table, and this is one of the next steps in finishing documenting this project. We still have to identify the depth of all of these wells and their catchment area, then present our findings in a report, presentation, and poster. Being able to go through this progress, first visually in seeing every single well, then further associating these locations on a map and being able to see the spread of the wells provided us with context and understanding of the scope of these wells. Next, being able to associate values and write up our findings, as well as do research into what has been done and why, will allow us to have a full understanding and present a full analysis on the work that has been done.

We are excited to continue moving forward with this project and to put together a report, presentation and poster that Biome will be proud of and that FAI will want to use!

Well Hunting Day Two - 10 more Wells

A Short Afternoon at Cubbon Park:

After yesterday's talk with Biome, in which we were advised to bring Manjunath with us to help show us where the wells are, which changed our entire experience. We were under the impression that he had managed the project, but it was clear he had spent a lot of time actually in the park because he knew the exact locations of all of the wells. In under an hour, we were able to mark out ten new wells, bringing our total up to 30 wells out of 70. We were lucky to have Manjunath for another reason, too: during our marking of well 29, a man sitting on the side of the well called out to us and asked us what we were doing. He was sitting with a group of other men, and seemed very entitled and stuck up. He repeatedly demanded to know who gave us permission, if we were working for the government, and where our documentation was. He didn't listen to our explanation that we were interning with Biome, and that we were marking out wells to build a cohesive map of the wells in Cubbon Park. We had to have Manjunath come over to mitigate, and he spent almost 15 minutes talking to this man. Upon talking to Uma and Manjunath after the fact, they told us that we shouldn't worry about being questioned this way, that this man just wanted to show off and act big. This is apparently common for Manjunath, and since he is officially permitted to work in the park, we were told that as long as he was there to guide us we would have no problem. It was an experience, an interaction that marked out an otherwise very productive afternoon in the park. We are looking forward to working with Manjuvath again tomorrow, and hopefully finishing marking out the rest of the wells so that we can move on to the report, presentation and poster!

Well Hunting around Cubbon Park

On this lovely Tuesday morning, GCIL 2020 interns went well hunting - that is, we went looking for the 70 recharge wells around Cubbon park, which are used to replenish aquifers by letting the water which gets trapped in the top foot and a half of soil flow downwards through concrete rings and coarse aggregate. We decided to go today without a guide, and to let ourselves explore the park and find the wells on our own. We had another Biome intern, Dennis, who is studying for his masters in economics and came from Germany to work with Biome, with us for the morning. He met us at our campus, and we all ubered to Cubbon Park, then walked to find paint with which to mark the wells. We decided on a nice, colorful blue, which would stand out and last on the concrete.

When we started going about the park, we quickly realized how big Cubbon Park is. We decided to start with the perimeter of the area we were in, and work our way into the park. To mark the wells, we used Google My Maps, which allows you to build your own map. We titled each well on My Maps R#, to indicate that they were recharge wells. Therefore, we can also come back and mark out the open wells if needed. We were able to mark out 20 of the 70 wells.

We had a couple of reflections as we were moving throughout the park. One, was that a guide who was a bit more familiar with the look of the wells and the general area in which there were more or less of them would be extremely useful. Second, we learned how to maximize the tasks at hand as a team. While we began by all walking together, by the end we were spread out walking in a line, calling to each other when we found a well. It was very difficult to know whether or not we missed a well, as some areas on our map definitely looked much emptier than others. We hypothesized that this could be due to the variable soil and depth of the aquifers below. The shallower the aquifers, and the greater their presence, the more wells should be in that area. We also learned that using Google Maps, and simply copy and pasting the coordinates onto Google My Maps, was easier and more accurate then just relying on the Google My Maps, which did not track our location very well.

We had a meeting in the afternoon with Biome to discuss projects which we would be working on during the rest of our time here. We decided that finishing the Cubbon Park project would be top priority, followed by the repair reports on the government schools around Bangalore, and creating new proposals for new schools to implement rainwater harvesting systems.

As usual, another productive, education, and fun day with Biome! So excited to continue this work and continue to build our skills and the projects.
