Until tap water arrives to faucet
Many facilities are necessary, and the maintenance entails a large amount of cost to send tap water to faucet.
Water supply business that is supported with water rate
"Maintenance of water source", "anti-disaster measures" conduct various affairs, "management of the quality of the water" "repairs leak of water explosion" "update improvement of water pipe" "driving of water purification plant and pumping station" to have you use channel for citizen's all of you in Water Works Bureau in peace forever.
And it is provided by water rate that is hardly expected to pay of expense to modify such duties that Water Works Bureau performs whereas general administrative services are served by tax.
This system is called "self-supporting accounting system" and is set as fundamental principle of management of "local government industry" including water supply business and is system that was set of "increase of the public welfare" that is role that local public entity should carry out to show economy of company.
Use of water rate that is main resources of water supply business is as follows.
About half of water rate is used for exchange such as water pipe which became old and return of money that we borrowed for water supply facility maintenance so far.
Exchange construction of water pipe which became old
It is necessary to exchange water pipe which became old for pipe (earthquake-resistant pipe) resisting earthquake to continue stably sending tap water. We change with the goal of 110km a year (we can change water pipe about 9,200km in the city in 80 years) in Water Works Bureau, and about 20 billion yen is necessary for the construction every year.
How does financial status of water supply business turn out after this?
As use quantity of water decreases by the spread of saving water apparatuses, water rate income is trend toward decreases, too. It is expected that this tendency will continue in future.
On the other hand, a large quantity of facilities which we maintained for the rapid economic growth period get older and reach update time sequentially. Therefore it will entail a large amount of cost for facility maintenance in future, and management becomes severer and severer.
Let's think about coming water supply business
We push forward efficiency of the following management in Water Works Bureau.
We work on reduction of the large staff fixed number and pushed forward efficiency of management, but it is anticipated that severer business condition continues until now to enter Yokohama-shi in situation of population decline. The council by experts of water supply business and corporate management installed "the role council such as Yokohama-shi water rates" in April, 2018 to fix the eyes on change of such a management environment in Water Works Bureau, and to consider about the way of water rate appropriate for Yokohama-shi in the future toward healthy water supply business administration which continued in the future and, after the deliberation of eight times until August, 2019, had report in September, 2019.
We collect thought as Water Works Bureau on the basis of this report and will explain in Yokohama City Council which is representative of citizen's in future.
