 Hello. I joined the agency in 2019 (Reiwa first year), and it is the second year water supply technical staff.
 Currently, at the Aoba Waterworks Office, we are conducting examinations and consultations on water works (installation work such as water supply pipes accompanying house construction) applications that customers request from water works shops.
 I joined the agency without knowing the word "su" of the water supply, and it was a start from scratch. At first I was worried about the future due to anxiety and tension, but my seniors are gentle and sometimes loving (!) Now I work with confidence because I teach with my own.
 The content of my work varies and I have a lot to learn, but I work hard every day to encourage my customers to thank them.
 The story changes, but the announcement of the pass is coming soon. I couldn't sleep at night because of anxiety at this time.…I'm sorry. How about you? I think it was a tougher exam than usual because of the influence of Korona. Thank you very much.
 I look forward to working with you!

 Hello. I joined the agency in 2017 and am a first-year student in water supply technology.
 There was a change in the workplace in April this year. In the past, I worked in the workplace at the forefront of customer service, and I was often grateful to the customers, so I realized that the water supply supported civil life.
 In my current workplace, I work on water management, which determines the movement of large water in water pipes. There are many tasks that change the flow of water, cut off water for construction, and have a wide range of effects, and it is very rewarding to respond promptly.

 Now, in Water Works Bureau is working to provide tap water 24 hours a day, 365 days a year.
 We are proud that there are few jobs that can be done for such clear goals, with 1,550 staff members working together.
 The water supply is based on public utilities, lives 3.7 million Yokohama citizens!
 I look forward to seeing this rewarding job with you.

 Hello. I joined the agency in 2019 (Reiwa first year), and it is the second year water supply technical staff.
 I work on drafting a "water cutoff plan" when I need to stop water pipe construction and water pipe leakage.
 In order to safely cut off the water on the day, we have been carefully preparing for several months, such as conducting site surveys, creating drawings, and publicizing areas where water cuts and turbid water may occur.
 I may be worried because I can't judge it myself, but I can work with peace of mind because experienced seniors will consult.

 Well, I'm from Shizuoka Prefecture. After passing the waterworks technician, I started looking for a rented house, but I didn't know where to live because I didn't know where to live, so it took time to prepare for the move. From this year, a business to lend facilities in Water Works Bureau's facilities as a residence from March before joining the agency to December of that year, so you can search for a rented house during that time. For this reason, I think that people from other prefectures can take the exam with confidence.
 Let's work together in Yokohama!

 Since this year, we have been operating at the water purification plant. Main duties include water quality monitoring, chemical injection, and facility management outside the site. I am proud to be able to do a large-scale job of supplying most of the tap water in Yokohama.
 Since I was a first-year student, there was no precedent when I took the exam, and I could imagine, "Is it the task of injecting chemicals at the water purification plant? ?' In fact, it covers not only the work of the water purification plant, but also the maintenance and repair of water pipes, water cutoff, and water operation.
 It is often difficult and sometimes troubled, but experienced seniors will teach you kindly and surprisingly.

 In City of Yokohama, Water Works Bureau purchased a forest in Doshimura from Yamanashi Prefecture in 1916 to maintain the stable flow rate and water quality of Doshikawa and supply high-quality tap water to Yokohama citizens. We are promoting management and conservation with the aim of enhancing environmental conservation functions such as water source recharge functions (*).
 The water supply business uses a part of the water cycle to supply tap water. The role of water source forests is important in order for water to circulate healthy and continue to receive the blessings it brings in the future.
 For more information, please refer to "Conservation of Doshimizu Source".

 ※ Rain and snow falling in the forest slowly rub the soil into the ground to create clean groundwater. This water becomes spring water.
  It's a river. Water source forests (forest soil) adjust the amount of rainwater flowing into the river to make it difficult to flood and clean water.
  I have one. This is called the "water source recharge function" and is also known as the "green dam".
