Nowadays

Nowadays, with the development of the technology and the growing school education,What is the real ground for this necessity? our students gradually realize the necessity of the water supply and the significance of protecting water supplying cannot be emphasized more. Therefore, I will offer this article to give students in ???NAU a better view about the water resource status and the protection of the water supply in our campus. Firstly, I will concentrate on the status of the water supply in NAU, which is the main project I want to discuss in my article. After that, I will focus on the problems of the water supply in our campus and natural-unfriendly behavior of our students to extract the solution. Then I will interpret what kind of benefit will this solution bring to us in the aspects like students’ life, the contraction of our campus, the environment around us, etc.

Overview
As is known to all, the significance of the water supply cannot be emphasized more, especially for our student who live in NAU every single day. Therefore, I will study the water resource status and the protection of the water supply in the NAU university. The available literature provides us the data and models for decision making of water resources systems analysis through case studies, the role of technology in water resources planning and managementthe water resources , and the research United States government carried out to estimate the Water supply in their country. And these researches provide us some inspiration about how to preserve the water resource in NAU.
Comparative Review
The data and models (David W Watkins?(Watkins, 2015), 2015) for decision making of water resources systems analysis through case studies will give us some advice: through the water resources systems analysis, the time will have a great influence on the choice of different period of method and the research should be divided into the short run and long run. The role of technology in water resources planning and management play an important role in water preservation, we should take care of the use of the technology when we carry out our researches. the United States government’s estimation of the Water ??supply in their country gives us a more general view about the water status nowadays. These statistics gives us the inspirations about the future estimation of our water status ???phrase bank, ????in NAU, which will offer us some inspirations about what kind of method can we do to preserve the water system in NAU.
Gaps in Available Research
Water resources systems analysis through case studies : data and models for decision making?David W Watkins, 2015?missed the water status in a specific place and all these studies neglect the solution of a specific place like NAU. Therefore, I am going to supply some more specific research about the water resource status in NAU and the solution of the water system in our campus among the following chapters.
Conclusions
Above all, I will offer you the solution of each problem in the following sections: the over use of the water resource in Wen Ji building, and the lavish of the water supply in NAU. ???phrase bank

Methodology
This study utilized the interview data from NAU students to access the status of water supply in this campus. How much do student in NAU know the water supply? To make our material more convincing, we deliver our questionnaire randomly to 256 students in NAU university. We conditionally selected the people of both genders, and most of them are the sophomore because they will give us some more comprehensive and objective statistics. A standard questionnaire is conducted online to obtain data on the following aspects:
– the causes of waste of water resources occurred in daily life and methods to address them
-Students’ suggestions about how to reduce the cost of water resource in our daily life
-attitude and responds towards some water-wasting behavior in NAU
-attitude towards the velocity of water of some toilet devices in NAU
-the popularity of the world water day in NAU
-students ‘ views on the water resources in NAU
-time which spends on hand washing
I also did some research on the water flow rate of the toilets in Wen Ji building to have a better view of the water supply status in NAU campus. What kind of research?

Chart2: attitude towards some water-wasting behaviors

Chart3: the grade of the informants

Chart4: Students’ view on the water resource in NAU

Chart5? the time which students spend on hand washing

Chart6? the popularity of the world water day in NAU

Chart7: The statistics of the water flow rate of the tap in Wen Ji building

Result
As is explicitly illustrated in the pie charts and bar charts above, we can have a more comprehensive view about the water availability and sustainable management in NAU on the issues which submitted in the questionnaire.
From the Chart 1, we can conclude that 78.4? of the students in NAU have the intention to prevent doing some water-wasting behavior which is much better than the rate of the international water-wasting behavior ratio in the societyExample of Topic sentence
Chart 1 reveals that (generalized findings of first chart)?David W Watkins, 2015?. When it comes to attitude towards some water-wasting behaviors (chart2), 47? of students chose the option that they dislike the water-wasting behavior but do nothing to stop it; besides, 42? of students think that they should take the responsibility to prevent this kind of bad behavior; the others(11?), however, think there is no necessity to worry about the water supply which leads to their acquiesce in these water-wasting behavior.
Chart5 indicates that 36? of the students spend less than 7 second on hand washing. 41? of the informants spend 7~15s on hand washing and 23? of the informants spend 15~25s. Moreover, only 1? of the informants wash their hand for over 30 seconds. Statistics on Chart 6 show that only 14? of informants knew the date of the World Water Day and 34? of informants had not heard of this anniversary. As it can be seen in the Chart7, the average water flow rate of the tap in Wen Ji building is 36 second per time, and the velocity of the tap is 5L per time on average.
According to the objective items in the questionnaire, most of the students had the awareness of the essentiality of availability and sustainable management of water and sanitation and showed much concern on water availability and sustainable management and sanitation in NAU. A student suggested that the campus should reduce the velocity of water of some toilet devices. Another student said that the NAU need to invest more money on water resources management and reasonable charge for dormitory water. For the method of promoting the water-saving awareness, some informants recommended the university to set up some water-saving course to acquaint the students with the status of the water supply in the world and grasp some useful water-saving skill.

Discussion and recommendations
The factors which contribute to the water-wasting behavior in NAU campus can be concluded in four aspects. The first reason is the water flow rate of some toilet devices is far beyond the water which demanded for the hand washing. It sets the obstacles for our students to cut down the use of the water and cause the inevitable lavish of the water supply. Besides, the dormitory water in NAU is free of charge, the students fail to realize the cost of the overuse of the water supply which leads to the lavish in their daily lives. Furthermore, although most of the informants know the essentiality of the water supply, their barely know the method to avoid the overuse of the water and most of them do not have the courage to prevent others from doing water-wasting behavior. The fourth aspect is that the school officials neglects the funds which should be spent on updating some water supply device to avoid the evitable lavish of the water supply, large amount of the taps in Wen Ji building are facing the mechanical fail and have trouble supplying the defined water flow rate.
The solution of the water-wasting behavior should firstly come with the instruction of the collage students about the awareness towards the water-saving methods. Although the sustainability of the water resource is widely acknowledged by the college students, the specialized instrument about the water saving is of great need. Therefore, it is crucial for NAU officials to offer some pre-college course about the specific methods of water saving in our daily lives. There is of no need to make the water-saving course to be a specialized course for a student who majored in economic or finance but this kind of course should be delivered before the ceremony held to signal the beginning of a school semester to give some instrument to the freshman in order to set them a water-saving discipline. The officials should try all means to eliminate the overuse and the lavish of the water supply and cultivate the good habit for these people who are going to join the labor force in the future.
Diminishing the water flow ratio and doing some regular updating of the water devices are also crucial for the water protection in NAU. According to the research and the questionnaire above, the water flow ratio and the water velocity of the water device in NAU is far beyond the amount which is demanded for the ordinary hand washing. Comparing with the standard hand washing process which is about 20 seconds per time (World Health Organization, 2016), the average water flow rate of the tap in Wen Ji building is 36 second per time and the velocity of the tap is 5L per time on average which is almost twice as much as the standard (World Health Organization, 2016). As it is demonstrated by the questionnaire, most of the students spend about 15 second for an ordinary hand washing, which indicates about two-thirds clean water are wasted during the procedure of hand washing. According to the objective statistics, each tap in Wen Ji building is used for about 850 times a day, which means 1.445t water are wasted; the lavished fund of NAU is about 2.6yuan per day for each tap (Water price List of Nanjing Waterworks Group Co. Ltd., 2018). The average price of an infrared induction tap is about 100 yuan, which can save about 950 yuan per year for each tap. Not only does it have some benefits to the water supply, but also cuts down the expenditure of the NAU.?????????????????
In conclusion, it can not be more urgent to raise the students’ awareness towards the water-saving methods. Diminishing the water flow ratio and doing some regular updating of the water devices should be completed as soon as possible in NAU by the school officials who take charge of the school fundamental construction. Meanwhile, everyone should join force to ensure the availability and sustainable management of water and sanitation in NAU and make NAU a place without the lavish of water supply.??conclusion??
