Characteristic of water for industrial use

Cheap rate

As for the water for industrial use, rate is cheap for simple clean water processing not to perform filtration and chlorination in comparison with tap water used at home.

Stable water supply

Ability for water supply has 362,000 cubic meters per day and can stably supply with water with the cause of the monitoring system, abundant water 24 hours a day, every day.

The naturally near quality of the water

It processes in water suitable for use form of customer and can use because it is water which water for industrial use precipitates natural water of high quality water source and treated.

→We support industrial activity with cheapness, abundant supply.
→As there is little electricity usage because we supply water using difference in elevation, and there are few medicines to use for clean water processing, it is eco-friendly water.

Use of water for industrial use

As industrial business

We can use water for industrial use by uses such as cooling water, water to adjust, product processing water, cleaning water, boiler water, raw materials water for the purpose of supply to industry (manufacturing industry, electric supply business, gas supply business, heat supply business).

As trivial routine duties water

We can use water for industrial use as trivial routine duties water including facility for agriculture such as air-conditioning, restroom water such as facilities for commerce, cleaning of animal building, plant factory.

※Water for industrial use is not available for a person's drinking.

The quality of the water of water for industrial use

We supply disposal of water sources water that precipitated natural water which are ryoshitsu same as waterworks as water for industrial use.

Water for industrial use way supplies area where water for industrial use way facility is maintained among Tsurumi Ward, Kanagawa Ward, Nishi Ward, Naka Ward, Hodogaya Ward, Asahi Ward, Isogo Ward, Totsuka Ward, Sakae Ward in city limits of Yokohama-shi with water.
For more details, please see brochure.

Structure of rate

Water rate for industry actually adds up two rates of basic use rate to calculate according to quantity of water that we used within base rate of flat rate based on basic quantity of water and the basic quantity of water and calculates.
In addition, there is excess rate to apply to quantity of water of part which we used more than basic quantity of water.

Basic quantity of water

We decide basic quantity of water per day based on contract of supply. Basic quantity of water does plan quantity of water per one hour to use most during one day 24 times and is decided.
In addition, we cannot reduce basic quantity of water in principle.

Quantity of water X 24 hours per one hour to use most in basic quantity of water = 1st
Basic quantity of water 25 cubic meters X 24 hours = 600 cubic meters (100 cubic meters unit) per one hour
※Basic quantity of water is necessary 200 cubic meters per day or more.

Rate unit price (tax-excluded per 1 cubic meter)

Rate unit price
Type Contents Unit price
Base rate Fixed sum to depend on basic quantity of water 25.1 yen
Basic use rate We used within the basic quantity of water per one hour
Rate to depend on quantity of water (basic use quantity of water)
4.0 yen
Excess rate We used more than basic quantity of water per one hour
Rate to depend on quantity of water (excess use quantity of water)
87.3 yen

Calculating formula of rate

Considerable sums such as water rate = (use of base rate + basics rate + excess rate) + consumption taxes for industry

  • Base rate = basics quantity of water X calendar day number X base rate unit price (25.1 yen)
  • Use of use of basic use rate = basics quantity of water X basics rate unit price (4.0 yen)
  • Excess rate = excess use quantity of water X excess rate unit price (87.3 yen)

Conceptual diagram of rate calculation


Calculation example of rate

Basic quantity of water 600 cubic meters/day, basic use quantity of water of one month 10,000 cubic meters, excess use quantity of water of one month in the case of 120 cubic meters (calculate in 30 days for one month)

Base rate 600 cubic meters *30 day *25.1 yen = 451,800 yen
Basic use rate 10,000 cubic meters *4 yen = 40,000 yen
Excess rate 120 cubic meters 3*87.3 yen = 10,476 yen
Considerable sum 50,227 yen such as consumption taxes
552,503 yen in total

Procedure until water supply

Consultation

Please confirm expenses that new water supply costs (setting of meter and cistern to receive, water supply facility construction, water supply facility construction).

Water supply application, basic quantity of water decision

Please submit water supply application. We decide basic quantity of water per day after examination. We cannot reduce basic quantity of water that we decided without special reason.

The water supply facility construction approximation delivery

When water supply facility construction (station construction) is necessary, please deliver construction cost approximation. We start water supply facility construction after the delivery confirmation.

Water supply facility construction

Please submit approval application of water supply facility construction (own expense construction). We can start water supply facility construction after the approval.

Water supply facility construction completion, payment

After water supply facility construction (station construction) completion, we have payment (return or addition) of construction cost.

Water supply facility construction completion, inspection and water supply start

We carry out examination of completion of water supply facility construction (own expense construction). We start water supply after the examination of completion pass.

※It is standard example, and the procedures mentioned above may be different.

Expense, facility necessary for new water supply

Setting of meter and cistern to receive

You go to meter suwari* every eight years based on setting of meter to calculate rate and regulations of measurement with burden on customer. As for the measurement, Water Works Bureau sets up flow measurement board for automatic inspection of a meter, but please install base of measurement board and power supply with burden on customer.
Please install cistern to receive to always receive water supply equally, and to possess at the time of water outage. When there is unavoidable reason by case by inevitability such as disaster occurrence or the damage accident of water for industrial use way facility or update construction of facility, it may cut off water supply.
In addition, we remit base rate based on standard when it cuts off water supply for period more than 24 hours.

Water supply facility construction (station construction)

Please bear construction expense when installation construction of water pipe (public facilities pipe) is necessary to customer to receive water supply with water for industrial use way newly.
We have you pay construction approximation in advance and pay the difference after the construction completion.
It is easy in Web! Initial expense estimate sheet

Water supply facility construction (own expense construction)

It enforces after customer asking for installation construction of service pipes from divergence part of water pipe (public facilities pipe) to site inner tray water tank in water supply works company, and receiving application, design examination, approval in Water Works Bureau, and it is necessary to receive completion inspection after the construction completion. We collect design examination fee and completion inspection fee.
[example] When with diameter 75mm or more, service pipe is 35,300 yen
