Derek Zoolander and my meh attempts to drill a well ......

Apologies, this post is super late! I am now actually finished with my time at Trailblazer in Siem Reap and am in Phnom Penh for one week to do a few interviews with NGOs here before going home on the 24th. Where has this entire summer gone?!

Part of what I had been doing with Trailblazer was going out with the well drilling team (with Sumnang, Vichet, and Kat) to villages around Siem Reap Province. The village chief chooses the family who receives the well, while the family chooses where they want the well. Trailblazer makes sure to work within existing village systems instead of waltzing up with wells and installing them, in turn increasing the sustainability of the project because it is integrated within the community.

I went to Trapeang Svay Village, Reul Commune, Puk District twice. Fun fact: “Trapeang Svay” means “Mango Pond.” I did not see any mangoes when I was there.

My first time in Trapeang Svay we were drilling the actual well. I pretty much embodied Derek Zoolander coal mining as I was basically utterly useless for drilling. This is not a machine drill-- this is a manual drill that you need to be pushing down onto while twisting. A sort of jump-push-twist movement that no machine in the gym can simulate well (or maybe, I need to go to the gym more). The pole is actually made from a bunch of poles linked together with a handled twisting contraption. This is tough work!! Simple and easy(ish) for the well drilling team when the water source is close to the surface, a lot harder for everyone when you have to drill through clay and rock (as we did).

Water being pumped into the truck. Pretty sure the water
buffalo just chilling was not too pleased.

To make the well at first before any drilling, we dug a small pit close to the would-be well that we then filled with water. This water was pushed down the hole (that would become the well source) to coax the pole to go deeper while drilling. 

When the pit ran out of water, we went to a river/field/pond nearby and got water using a pump and lots of tarps (and in the end, most of the water ended up on the ground, not in the pit) laid out in the back of the truck. Two little boys accompanied us for this (although this was midday, many schools are only for half days), and Sumnang and Vichet seemed to trust them more than me. This might have been perhaps due to my Derek Zoolander status or my being a woman, which sadly is more likely to be the main factor.

We continued drilling, only breaking for a meal of morning glory (Khmer water spinach), rice, and oily bony fish with a red tomato/onion sauce. At the end of day, we hit eighteen meters. We tried to pump water from the ground (an up and down movement with one pipe within the other) but sadly with no avail. We had to take out the piping from the well and succumb to the fact that the next day we would be back to drilling. In the end, this well had to be twenty-five meters deep, while at other homes in the village ten meters deep was sufficient.

In Trapeang Svay the second time but at different part of the village, I could help a bit more. This time, rather than drilling, we were making the cement base for the well. Again, this was completely manual. We had no cement machine, but rather I manually mixed the Camel cement mix and sand together with water and a shovel to make the functioning cement.

1. We dug a dirt platform and flattened it right in front of where the well pump was.
2. We then put large rocks in the dirt--still retaining platform’s flat structure (in other words, the rocks we used were flat on at least one part).
3. We filled in the dirt gaps surrounding the large rocks with smaller stones.
4. We built a brick square around the well’s platform that would later become the raised edge of the well structure.
5. We put the concrete mixture on the bricks, and then the stone.

This is super confusing without a plethora of visuals that my slow internet prohibits me from uploading (hopefully the ones that did upload are okay!!), but I hope it makes some sense! Basically: ground --> platform base -->  walls --> finished well. I have noticed that whenever going into villages for filter installation or well drilling, the project seems to encompass the entire village and not just the filter or well team. While in the US one might not help the contractors re-doing your kitchen, in Cambodia this seems completely normal and appropriate.

The mom at this home seemed to have really taken a liking to me, especially as I was helping her son with his English (he was perhaps the only child who actually would talk to me when I spoke to him without parents’ help!). I also sat and talked with her about all of her children, told her about my family, and also looked through her daughter's drawing book which was adorable. Her school notebooks showed photos of (still) current prime minister Hun Sen and his wife--unsurprising to say the least. The mom also wanted to make sure that I was out of the sun to protect my super white skin, and kept telling me to be very careful with my head because I am so tall. When she found out that I was vegetarian, she sent her daughter out to buy me rambutans! I was elated at their kindness, even though I have no qualms about having morning glory and rice every day.

Filter Installation~~

A shop at Lolei Village

All of the time I have spent sifting sand, sifting gravel, washing sand, and washing gravel has paid off! On Friday, I went to Lolei Village outside of Siem Reap to install eight water filters which--let me tell you, reader--was an incredibly long and arduous day.

I rode out to the village on the back of a pick up truck, and borrowed Bone-knee's (not how you spell his name, but how I pronounce it) über Cambodian hat that was camouflage colored with a lovely flap that covered my neck and then wrapped across my face to snap onto the other side. Literally my entire head, neck, and face except for my eyes (which had sunglasses) were covered. This was great, as this hat was going to do more than any sunscreen I owned would. As well, the dust flying everywhere would not stick to my sunscreen and sweat, but only my sweat. Much better!

A family next to their filter

The village had no electricity, only one generator in one of the nicer houses. There was one dirt road that went through the village, houses lining either side, and a few small shops. Behind the houses were either more houses or gardens / farms / open land. Most of the villagers were at home to receive the filters, and from what I observed at least, about half of the children went to school.

We installed eight filters, which took a total of about six and a half hours including lunch, installation time, and driving time. The filter mold comes from a Canadian organization called CAWST (The Centre for Affordable Water and Sanitation Technology) that creates a lot of filter molds, I am told, for NGOs all over developing countries. The filters are immensely heavy, as they are made out of concrete, and so are the bags of sand (I really never realized how heavy sand could be). The filters are relatively easy to install seeing as they are just plopped on the ground wherever the family wants them (and this means they can be near a toilet or sewage source, but because the filter does not draw on this water (necessarily :/ ) this is fine). On Friday, we installed the filters either next to their well or next to their kitchen area.

Putting well water into a filter 

Basically, we wheeled the filter on a dolly to where the family wanted it installed. The family pays 13,000Riel, or $3.25, for the filter that then goes to the village fund. The price in 2012 was $2.60, but due to inflation, I am told, the price increased. This place has to be level in order to function properly, and in a few cases we had to add sand or a pebble or two underneath the filter in order to ensure this. We then put some water into the filter, pour the large gravel into the bottom, and level it. I leveled the gravel as I can reach the bottom of the filter with my rather long arms and still not get my sleeve wet. Then, we pour in the small pebbles, level these again, and then the sand which two people need to pick up to dump in due to its immense weight. We level the sand carefully without packing it in, and also then clean the filter using water and a cap-full of bleach. Finally, we pour more water into the filter and place the blue perforated filter contraption on top of this sand and water (it fits nicely into the concrete filter). You pour water on top of the blue filter and then, after about two weeks of being installed, clean water comes out of the drinking end.

The two week waiting period is for the biofilm to develop and mature in the sand. The biofilm is created in the sand to trap bacteria in the water (it will consume bacteria such as E.Coli), and is developed organically and biologically specific to that water source. A biofilm for pond water would be different from a biofilm for well water, for example. The biofilm traps about 40% of the bacteria, while 60% or so of the other objects / not-so-great minerals in water (if there is a lot of iron, for example) is physically trapped with the blue filter or does not make it through the sand at all. For example, pond water had a lot of silt that is physically blocked with the sand and/or blue filter. Biosand filters trap about mid 80s to high 90s % of the bacteria and objects found in water, with percentages varying due to maintenance and quality of the original water source. When the biofilm develops after about two weeks, clean water is good to go. The gravel serves as another physical filter to maintain the integrity of the sand part of the filter, preventing it from going through the outlet tube.

A page from a booklet

The cleaner the water is going into the filter, the cleaner the water is coming out. Therefore, if you use water from a stream that feces run into, the water that comes out of the filter will not be as clean as water coming from a well 30 meters or so from a toilet. With each filter Trailblazer installs, they also hand out and explain a blue booklet in Khmer with pictures to show how to maintain the filter, how to use the filter, and how to drink/use water responsibly and sustainably in general. The pictures show fenced in livestock so they do not poo in streams, and also enclosed toilet areas, for example.

Drunk driving and helmet notice

Rice (duh), sauce, fish, and omlet

We stopped for lunch at one of the houses that actually belongs to one of Trailblazer's staff. His wife cooked a great meal of rice (of course), a sauce for the rice that consisted of chili and some sort of cilantro-esque herb, grilled fish, and a great omlet. While eating the omlet, Sotirot (again, not how you spell his name but how I pronounce it) asked me what the eggs of the fish were called. "Fish eggs," I said, "or from certain fish, it is called caviar and this is very expensive." "Ohhhhhh" he said, very excited. "There is caviar in this omlet!"

I am vegetarian, and trying to not eat fish in the middle of nowhere. So much for that one. But it did explain why the food tasted so good!

Also on the Lolei trip, I held three more naked babies that I loved but God was I worried about them peeing on me. We also went by a makeshift school with English and Khmer letter charts, as well as an English parts-of-the-body chart. There was also a fruit poster in English, and randomly in Chinese, with fruits I don't even think they readily have in Cambodia, like blueberries. The man at this house said he learned English with monks at the pagoda, and hopes to teach English to Khmer students for free. I also witnessed the only anti-drunk driving poster I have seen in Cambodia, and I am told that drunk driving is actually a serious problem.

At about 3:15, I climbed back onto the back of the truck, put Bone-knee's fashionable hat back on, and went home.
