Phase 3: Interpreting Information

Updated 5 years 2 weeks ago

After posting what I know and what I want to know in Phase 1, now I have to do some background research to help me understand more and help me come up with the big questions. In this phase, I will first do some background research about my topic, water usage/treatment, and when I am in Xizhou, I will have to collect Information from local contacts to make my research more accurate.

Background Information:

The "mother lake" of Yunnan Province is called Lake Erhai, and most of the fresh water in Xizhou comes from Lake Erhai[1]. Most of the people at Xizhou are farmers, and they know quite a lot about the irrigation system over there[1]. There is three aqueducts in Xizhou, the first one pumps water from Lake Erhai to Xizhou, and the second and third pumps water from further places[1]. Before the aqueduct in Xizhou used to be used to deceiver water to further places and people in Xizhou have to get water from the top of the Cang Shan mountains[1].  Water in the aqueducts goes to the farm by canals, which the farmers made[1]. It says that in Yuanna, they use cutting edge technologies to filter the water[2]. Sewer water and water from agricultural land will all go into Lake Erhai, than it will flow into the water treatment entrance, which will add oxygen to the water than filter the water. After cleaning the water, it will go to a artificial wetland then flow into Lake Erhai[3].  Lake Erhai has change so much over a long period of time[4]. In the past, the water was clean, that kids could drink from it or swim inside[4]. However, now, it is getting more polluted and people only allow to fish 2 month a year[4].

Information From 3 to 5's:

After interviewing Ms. Linden, I learned that the government are building the wetland for the water that is coming down from the mountain and the waste water will all go to the wetland first. After interviewing Ms. Mai, I learned that there are many water purifiers next to the lake, about every 500-meter. The government did that to make sure everyone has clean water.

Information From Local Contacts:

Ms. Zhong (owner of a western restaurant):

•    She uses 30L of water every month because she owns a big restaurant.

•    She is trying to conserve their water use by using the dishwater and the laundry water to flower.

•    If the water price goes up, she will continue using that method

•    On the May holiday, there is more people come the restaurant, that may cause the increase of water usage, because some tourist went to wash their hand, they need to clean more plate and they need to clean more food.

•    After harvesting all of the garlic, which does not need that much water, they are now planting the rice

•    The government has installed more pipes for the irrigation system.

This helps me to understand more about how the size of the restaurant many affect the usage of water.

Now I have finished my Phase 3 work because I got all the information that I need to complete the finial product. I am ready to move on to Phase 4, so continue following story of water usage/treatment. 

 

Hi guys, I am Jack Y. I am a Microcampus student and I was at Xizhou. I have a brother named Jerry and I also have a sister named Amelia. I like Microcampus because it takes me outside of my personal bubble, and I also like my project, which is Water usage/treatment. Microcampus have helped me understand a lot of things, I also understand myself better than before.
