As an example of current water charge calculation, water charge (water supply) is calculated as (basic charge + metered charge) x 1.08, and sewerage charge is calculated as (amount calculated based on the rate list) x 1.08. It is calculated by Read the reading date of the water meter (water flow meter) installed on the service pipe through which water flows, and calculate the water meter reading on the previous meter reading date from the reading date of the meter reading in the meter reading month. The subtracted figure is taken as the amount of water used for the month, and the amount of water used is converted into a metered rate to calculate the water charge.

The building is equipped with at least one of the following equipment: a cooling tower that recirculates cooling water for air conditioning equipment, a humidifier that humidifies indoor spaces, a mist generator that sprays mist into indoor spaces, and a dryer.

Compared to the case where water charges are calculated, the water charges borne by tap water users are lower, and each user can enjoy the benefits. In the water rate management system, the server outputs the first water rate calculated based on the amount of sewage discharged as the amount of water used, so each user calculates the amount of sewage discharged excluding the tap water (tap water) consumed in the equipment as the amount of water used. The amount of profit from the calculated first water charge can be known.

A water rate management system in which a sewage flow meter is installed on a lid that is attached to the final basin or manhole so that it can be opened and closed is a water rate management system in which the sewage flow meter is installed on the lid of the final basin or manhole, so that the water flows to the final basin or manhole. Not only can the amount of sewage discharged by sewage be measured reliably, but it also does not require large-scale construction work such as constructing a concrete pit underground to install a sewage flow meter, and can be easily installed as a sewage flow meter. In addition to being able to install the sewage flow meter in the final basin or manhole, maintenance such as inspection and repair of the sewage flow meter can be easily performed.

The water rate management system, in which the server calculates the ratio of the sewage discharge volume measured by the sewage flow meter to the water consumption measured by the water flow meter while the cooling tower is in operation, outputs the calculated ratio. By checking the ratio of the amount of sewage discharged to the amount of water used at It is possible to know the degree of benefit that a user can receive if the water charge is calculated using the amount of sewage discharged excluding the tap water used as the amount of water used.

If the rate calculated while the cooling tower is running exceeds the preset set rate, the server increases the output of the cooling tower so that the rate falls within the set rate, and the rate calculated while the cooling tower is running falls below the set rate. If the consumption (evaporation amount) of tap water (tap water) in the cooling tower is low, the water rate management system reduces the output of the cooling tower so that the ratio falls within the preset ratio. If the ratio exceeds the set ratio, the server increases the output of the cooling tower so that the ratio falls within the set ratio, so that the cooling tower can reliably perform heat exchange (energy exchange) using tap water. In addition to making effective use of the cooling tower, the building's living environment can be maintained at an optimal level. In the water rate management system, if the consumption (evaporation amount) of tap water in the cooling tower is high and the calculated ratio is less than the set ratio, the server reduces the output of the cooling tower so that the ratio falls within the set ratio. Therefore, the amount of consumption (amount of evaporation) of tap water (tap water) in the cooling tower and the power consumption in the cooling tower can be reduced, and the energy saving of the building can be achieved.

It is possible to know the degree of benefit that the user can receive if the water charge is calculated using the amount of sewage discharged excluding the tap water consumed in the humidifier as the amount of water used.

If the ratio calculated while the humidifier is running exceeds the preset set ratio, the server increases the output of the humidifier so that the ratio falls within the set ratio, and the ratio calculated while the humidifier is running exceeds the set ratio. If the rate is below the set rate, the server reduces the output of the humidifier so that the rate falls within the set rate. If the ratio exceeds the preset ratio, the server increases the output of the humidifier so that the ratio falls within the set ratio, so the humidifier uses tap water to reliably humidify the indoor space. Therefore, the humidifier can be used effectively, and the living environment of the building can be optimally maintained by the humidifier. In the water rate management system, if the amount of tap water (sprayed water) consumed by the humidifier is large and the calculated ratio is less than the set ratio, the server adjusts the output of the humidifier so that the ratio falls within the set ratio. Therefore, it is possible to reduce the consumption (amount of sprayed water) of tap water (water supply) in the humidifier and the power consumption in the humidifier, and it is possible to save energy in the building.

A water rate management system in which the server calculates the ratio of the amount of sewage discharge measured by the sewage flow meter to the amount of clean water used measured by the water flow meter while the mist generator is in operation, and outputs the calculated ratio, By checking the ratio of the amount of sewage discharged to the amount of water used while the device is in operation, the percentage of tap water (tap water) consumed (sprayed) in the mist generator while the mist generator is in operation can be determined. It is possible to know the degree of benefit that the user can receive if the water charge is calculated using the amount of sewage discharged excluding the tap water consumed in the mist generating device as the amount of water used.

If the ratio calculated while the mist generator is operating exceeds the preset setting ratio, the server increases the output of the mist generator so that the ratio falls within the set ratio, and the ratio calculated while the mist generator is operating exceeds the preset ratio. If the ratio is below the set ratio, the server reduces the output of the mist generator so that the ratio falls within the set ratio. If the calculated ratio exceeds the preset ratio, the server will increase the output of the mist generator so that the ratio falls within the set ratio, so the mist generator will not be able to use tap water. The mist can be sprayed into the indoor space to reliably cool the indoor space, and the mist generator can be used effectively, and the living environment of the building can be optimally maintained by the mist generator. In the water rate management system, if the amount of tap water (sprayed water) consumed by the mist generator is large and the calculated ratio is less than the set ratio, the server adjusts the mist generator so that the ratio falls within the set ratio. Since the output is reduced, it is possible to reduce the amount of tap water (spray amount) consumed by the mist generator and the power consumption of the mist generator, and it is possible to save energy in the building.

The water rate management system, in which the server calculates the ratio of the amount of sewage discharge measured by the sewage flow meter to the amount of clean water used measured by the water flow meter while the dryer is operating, and outputs the calculated ratio, By checking the ratio of the amount of sewage discharged to the amount of water used during operation, it is possible to know the percentage of tap water (clean water) consumed (evaporated) in the dryer while it is operating. It is possible to know the degree of benefit that a user can receive if the water charge is calculated using the amount of sewage discharged excluding the tap water consumed in the dryer as the amount of water used.

If the percentage calculated while the dryer is running exceeds the preset set percentage, the server increases the output of the dryer so that the percentage falls within the set percentage, and the percentage calculated while the dryer is running exceeds the set percentage. If the ratio is below the set ratio, the server reduces the output of the dryer so that the ratio falls within the set ratio.In the water rate management system, the amount of tap water (evaporation) consumed by the dryer is low, and the calculated ratio If the ratio exceeds the preset percentage, the server will increase the output of the dryer so that the percentage falls within the preset percentage, so the dryer can be used effectively and the dryer can reliably remove the objects. Can be dried. In the water rate management system, if the consumption (evaporation amount) of tap water in the dryer is large and the calculated ratio is less than the set ratio, the server adjusts the output of the dryer so that the ratio falls within the set ratio. Therefore, it is possible to reduce the amount of consumption (amount of evaporation) of tap water (tap water) in the dryer and the power consumption in the dryer, and it is possible to reduce the energy consumption of the building.

When the [sewerage/water supply ratio] display button 4d is tapped, the building identification information and the ratio output signal are transmitted from the smartphone 15 to the cloud 11 (server). The cloud 11 (server) identifies the factory 30a (building) based on the building identification information, identifies the URL and IP address of the smartphone 15, and calculates the water consumption (cumulative amount) calculated by the ratio calculation means. Ratio of sewage drainage amount (cumulative amount) excluding rainwater drainage amount, clean water usage amount (cumulative amount) stored by the water usage storage means, sewage drainage amount (cumulative amount) stored by the sewage usage amount storage means, rainwater usage Send the amount of rainwater drainage (cumulative amount) etc. stored by the amount storage means to the smartphone 15 via the Internet, and output (display) the ratio, water consumption amount, sewerage drainage amount, rainwater drainage amount, etc. to the smartphone 15 (ratio output means) .

A ratio output screen shown in FIG. 8 is output (displayed) on the touch panel 31 of the smartphone 15. The ratio output screen in Figure 8 includes a [User number] display area 8a that displays the user number, a [Water supply amount] display area 8b that displays the amount of water used, and a [Usage period] display that displays the amount of water used. Area 8c, [Sewage drainage amount] display area 8d, which displays the amount of sewerage drainage, [Rainwater drainage amount] display area 8e, which displays the amount of rainwater drainage, [Usage period] display area 8f, which displays the usage period of sewage and rainwater, and percentage display A [Ratio] display area 8g, a [Menu screen] display button 8h, and a [Logout] button 8i are output (displayed).

The water rate management system 10 checks the ratio of the sewage drainage amount (cumulative amount) excluding the rainwater drainage amount (cumulative amount) to the water usage amount (cumulative amount) while the cooling tower 16 is in operation. It was possible to know the proportion of tap water (tap water) consumed (evaporated) in the cooling tower 16 during the operation of the cooling tower 16, and the water charge was calculated using the amount of sewage discharged excluding the tap water consumed in the cooling tower 16 as the amount of water used. It is possible to know the degree of benefit that a user can receive in a case.

The cloud 11 (server) compares the ratio calculated by the ratio calculation means while the cooling tower 16 is in operation with a preset setting ratio, and determines whether the ratio calculated by the ratio calculation means while the cooling tower 16 is in operation is set in advance. When the set ratio is exceeded, the output of the cooling tower 16 is increased so that the ratio falls within the range of the set ratio (first output increasing means).

For example, for Cloud 11 (server), the setting ratio is 85 to 87%, and the calculated ratio is 90% (if the amount of water used is ^100m3 and the amount of sewage discharge is ^90m3 , the ratio is 90%) In the case of Send. The control unit of the cooling tower 16 increases the output of the cooling tower 16 according to the output increase signal (including the output increase rate) received from the communication equipment (cloud 11 (server)).

The water rate management system 10 allows the cloud 11 (server) to Since the output of the cooling tower 16 is increased, heat exchange (energy exchange) using tap water (tap water) can be reliably performed in the cooling tower 16, and the cooling tower 16 can be used effectively. Accordingly, the living environment of the factory 30a (building) can be maintained optimally.

The cloud 11 (server) compares the ratio calculated by the ratio calculation means while the cooling tower 16 is in operation with a preset setting ratio, and determines whether the ratio calculated by the ratio calculation means while the cooling tower 16 is in operation is lower than the set ratio. In this case, the output of the cooling tower 16 is reduced so that the ratio falls within the range of the set ratio (first output reduction means).

For example, for Cloud 11 (server), the setting ratio is 85 to 87%, and the calculated ratio is 80% (if the amount of water used is ^100m3 and the amount of sewage discharge is ^80m3 , the ratio is 80%) In the case of Send. The control unit of the cooling tower 16 reduces the output of the cooling tower 16 according to the output reduction signal (including the output reduction rate) received from the communication equipment (cloud 11 (server)).

The water rate management system 10 allows the cloud 11 (server) to control the output of the cooling tower 16 when the consumption amount (evaporation amount) of tap water (tap water) in the cooling tower 16 (equipment) is large and the calculated ratio is lower than the set ratio. Therefore, the consumption (evaporation amount) of tap water (tap water) in the cooling tower 16 and the power consumption in the cooling tower 16 can be reduced, and the energy saving of the factory (building) can be achieved.

The humidifier 17 sprays dry tap water from the factory 30b to humidify the interior of the factory 30b for the purpose of preventing static electricity, preventing dust from floating, and preventing dust from adhering. Since the humidifier 17 widely sprays clean water indoors in the factory 30b, it consumes (uses) a large amount of tap water (tap water). A wireless communication device (wireless LAN) (not shown) is connected to the control section of the humidifier 17. The control unit of the humidifier 17 uses a wireless communication device (wireless LAN) to send an operation signal (including building identification information) or a stop signal (including building identification information) of the humidifier 17 to the communication equipment of the factory 30b. The communication equipment transmits an operation signal (including building identification information) or a stop signal (including building identification information) of the humidifier 17 to the cloud 11 (server) via the Internet.

They are the same. Note that the amount of clean water used is the amount of clean water used in the cooling tower 16 (equipment) and humidifier 17 (equipment) (or humidifier 17) over a specified period (use period of one month, two months, etc.). This is the cumulative amount of water used and the cumulative amount of clean water used in the kitchen 32 (kitchen), bathroom 33, and toilet 34 for a specified period (use period such as 1 month or 2 months). . The amount of sewage discharged is the amount of water used in the kitchen 32 (kitchen), bathroom 33, and toilet 34, excluding tap water consumed (evaporated) in the cooling tower 16 (equipment) and humidifier 17 (equipment) (or humidifier 17). This is the cumulative amount of sewage discharged during a predetermined period (use period such as one month or two months).

The first water charge is cheaper than the second water charge for the amount of water used (accumulated amount), which includes the tap water consumed in the cooling tower 16 and the tap water (tap water) consumed in the humidifier 17. The water charge difference calculated by the water charge difference calculation means is negative. Note that even if the cooling tower 16 is stopped or only the humidifier 17 is installed in the factory 30b, the sewage water excluding the tap water (tap water) consumed (sprayed) in the humidifier 17 Since the first water rate for the amount of waste water (accumulated amount) is cheaper than the second water rate for the amount of clean water used (accumulated amount) including the tap water (tap water) consumed in the humidifier 17, the water rate difference is The difference in water charges calculated by the calculation means is negative.

In the ratio calculation means, the cloud 11 (server) receives the operation signal of the cooling tower 16 from the communication equipment of the factory 30b (control unit of the cooling tower 16), and receives the operation signal of the humidifier 17 from the communication equipment of the factory 30b (control unit of the humidifier 17). (including when only the humidifier 17 operation signal is received), the cooling tower 16 and the humidifier 17 are in operation (including when only the humidifier 17 is in operation) unless a stop signal is received. The amount of sewage drainage (integrated amount) measured by the sewage flow meter 12 relative to the amount of clean water used (integrated amount) measured by the water flow meter 13 in Calculate the ratio of sewage drainage volume (integrated volume) excluding rainwater drainage volume measured by

The measured sewage drainage amount is transmitted to the cloud 11 (server), and the cloud 11 receives the sewage drainage amount from the sewage flow meter 12 (the sewage drainage amount excluding rainwater drainage amount) as the water usage amount. 1 To calculate the water charge, the sewage flow meter 12 measures the tap water consumed (evaporated and sprayed) in the cooling tower 16 and humidifier 17 (if the cooling tower 16 is stopped or not installed, the water is humidified). The first water charge can be calculated using the amount of water used as the amount of sewage discharged (excluding tap water consumed (sprayed) in the device 17), compared with the case where the water fee is calculated using the amount of tap water used as the amount of water used. However, the water charges borne by tap water users will be reduced, and each user will be able to enjoy the benefits.

The water rate management system 10 installed in the factory 30b in FIG. Since each user outputs (displays) the tap water consumed (evaporated and sprayed) in the cooling tower 16 (equipment) and humidifier 17 (equipment) (when the cooling tower 16 is stopped or the cooling tower 16 is not installed) In this case, it is possible to know the amount of profit based on the first water charge, which is calculated by using the amount of sewage discharged excluding the tap water consumed in the humidifier 17 as the amount of water used.

A ratio that is the ratio of the amount of sewage drainage (cumulative amount) (if the cooling tower 16 is stopped or is not installed, the amount of rainwater drainage (cumulative amount) to the amount of water used (cumulative amount) while the humidifier 17 is in operation By checking the percentage of sewage drainage volume (accumulated volume) excluding the amount of sewage water discharged (accumulated volume), it is possible to determine the amount of tap water (tap water) that was consumed (evaporated and sprayed) in the cooling tower 16 and humidifier 17 while the cooling tower 16 and humidifier 17 were in operation. ), and the tap water consumed in the cooling tower 16 and the humidifier 17 (if the cooling tower 16 is stopped or the cooling tower 16 is not installed, the tap water consumed in the humidifier 17) It is possible to know the degree of benefit that users can receive if the water charge is calculated using the amount of sewage discharged excluding the amount of water used as the amount of water used.

The cloud 11 (server) calculates the ratio calculated by the ratio calculation means while the cooling tower 16 and humidifier 17 are in operation (if the cooling tower 16 is stopped or the cooling tower 16 is not installed, the ratio is calculated while the humidifier 17 is in operation). The ratio calculated by the ratio calculation means) is compared with a preset setting ratio, and the ratio calculated by the ratio calculation means while the cooling tower 16 and humidifier 17 are in operation (when the cooling tower 16 is stopped or when the cooling tower 16 is installed) is compared with a preset setting ratio. If the ratio calculated by the ratio calculation means during operation of the humidifier 17 exceeds a preset ratio, the cooling tower 16 and the humidifier 17 are adjusted so that the ratio falls within the set ratio. The output (when the cooling tower 16 is stopped or when the cooling tower 16 is not installed, the output of the humidifying device 17) is increased (second output increasing means).

For example, for Cloud 11 (server), the setting ratio is 83 to 85%, and the calculated ratio is 88% (if the amount of water used is ^100m3 and the amount of sewage discharge is ^88m3 , the ratio is 88%) In this case, an output increase signal (including the output increase rate) is transmitted via the Internet to the communication equipment installed in the factory 30b, and the communication equipment transmits the output increase signal (including the output increase rate) to the control unit of the cooling tower 16 and the control unit of the humidifier 17 (or the humidifier The output increase signal (including the output increase rate) is transmitted to the controller (control unit 17).

If the consumption of tap water in the humidifying device 17 is small and the calculated ratio exceeds the preset setting ratio, the cloud 11 (server) installs the cooling tower 16. Since the output of the humidifier 17 (or the output of the humidifier 17) is increased, heat exchange (energy exchange) using tap water (tap water) can be reliably performed in the cooling tower 16, and the output of the humidifier 17 is increased. The indoor space of the factory 30b can be reliably humidified using tap water (tap water), and the cooling tower 16 and the humidifying device 17 (or the humidifying device 17) can be used effectively. The living environment of the factory 30b (building) can be optimally maintained by the device 17 (or the humidifying device 17).

The ratio calculated by the ratio calculation means (if the cooling tower 16 is not installed, the ratio calculated by the ratio calculation means) is compared with the preset setting ratio while the cooling tower 16 and humidification device 17 are in operation. If the ratio calculated by the ratio calculation means during operation of the cooling tower 17 is lower than the set ratio, the output of the cooling tower 16 and the humidifier 17 (when the cooling tower 16 is stopped or when the cooling tower 17 is If not installed, the output of the humidifier 17 is reduced (second output reduction means).

For example, Cloud 11 (server) has a setting ratio of 83 to 85%, and the calculated ratio is 81% (if the amount of water used is ^100m3 and the amount of sewage discharged is ^81m3 , the ratio is 81%) In this case, an output reduction signal (including the output reduction rate) is transmitted via the Internet to the communication equipment installed in the factory 30b, and the communication equipment transmits the output reduction signal (including the output reduction rate) to the control unit of the cooling tower 16 and the control unit of the humidifier 17 (or the humidifier The output reduction signal (including the output reduction rate) is transmitted to the controller (control unit 17). The control unit of the cooling tower 16 reduces the output of the cooling tower 16 according to the output reduction signal (including the output reduction rate) received from the communication equipment (cloud 11 (server)), and the control unit of the humidifier 17 The output of the humidifying device 17 is reduced in accordance with the output reduction signal (including the output reduction rate) received from the humidifier 11 (server).

The water rate management system 10 installed in the factory 30b in FIG. If the consumption of tap water in the humidifying device 17 is large (if the cooling tower 16 is not installed) and the calculated ratio is lower than the preset setting ratio, the cloud 11 (server) Since the output of the humidifier 17 (or the output of the humidifier 17) is reduced, the consumption (evaporation amount and spray amount) of tap water (tap water) in the cooling tower 16 and humidifier 17 (if the cooling tower 16 is not installed) can reduce tap water consumption in the humidifying device 17) and power consumption in the cooling tower 16 and humidifying device 17 (power consumption in the humidifying device 17 if the cooling tower 16 is not installed).

The mist generator 18 sprays fine mist of 10 microns or less from a mist nozzle installed indoors for the purpose of cooling the indoor space of the factory 30c. Since the mist generator 18 widely sprays clean water indoors in the factory 30c, it consumes (uses) a large amount of tap water (tap water). A wireless communication device (wireless LAN) (not shown) is connected to the control section of the mist generator 18. The control unit of the mist generator 18 uses a wireless communication device (wireless LAN) to send an operation signal (including building identification information) or a stop signal (including building identification information) of the mist generator 18 to the factory 30c. The communication equipment transmits an operation signal (including building identification information) or a stop signal (including building identification information) of the mist generator 18 to the cloud 11 (server) via the Internet.

If the cooling tower 16 is stopped or the cooling tower 16 is not installed, the amount of tap water consumed by the mist generator 18 is low, and if the calculated ratio exceeds the preset ratio, the cloud 11 (server) Since the output of the cooling tower 16 and the mist generator 18 (or the output of the mist generator 18) is increased, heat exchange (energy exchange) using tap water (tap water) can be performed reliably in the cooling tower 16, The mist generator 18 uses tap water (tap water) to spray mist into the indoor space to reliably cool the indoor space, making the cooling tower 16 and the mist generator 18 (or the mist generator 18) effective. In addition, the cooling tower 16 and the mist generator 18 (or the mist generator 18) can optimally maintain the living environment of the factory 30c (building).

The cloud 11 (server) calculates the ratio calculated by the ratio calculation means while the cooling tower 16 and the mist generator 18 are in operation (when the cooling tower 16 is stopped or the cooling tower 16 is not installed, the ratio is calculated by the ratio calculation means) while the cooling tower 16 and the mist generator 18 are in operation. The ratio calculated by the ratio calculation means while the cooling tower 16 and the mist generator 18 are in operation is compared with the ratio calculated by the ratio calculation means during the operation of the cooling tower 16 and the mist generator 18 (if the cooling tower 16 is not installed, , when the ratio calculated by the ratio calculating means while the mist generator 18 is in operation is lower than the set ratio, the output of the cooling tower 16 and the mist generator 18 (when the cooling tower 16 is stopped) is lower than the set ratio. or when the cooling tower 16 is not installed, the output of the mist generator 18 is reduced (third output reduction means).

For example, for Cloud 11 (server), the setting ratio is 82 to 84%, and the calculated ratio is 79% (if the amount of water used is ^100m3 and the amount of sewage discharged is ^79m3 , the ratio is 79%) In this case, an output reduction signal (including the output reduction rate) is transmitted via the Internet to the communication equipment installed in the factory 30c, and the communication equipment transmits the control unit of the cooling tower 16 and the control unit of the mist generator 18 (or An output reduction signal (including the output reduction rate) is transmitted to the controller (control unit of the generator 18). The control unit of the cooling tower 16 reduces the output of the cooling tower 16 according to the output reduction signal (including the output reduction rate) received from the communication equipment (cloud 11 (server)), and the control unit of the mist generator 18 reduces the output of the cooling tower 16 according to the output reduction signal (including the output reduction rate) received from the communication equipment (cloud 11 (server)) The output of the mist generator 18 is reduced in accordance with the output reduction signal (including the output reduction rate) received from the cloud 11 (server).

If the cooling tower 16 is stopped or the cooling tower 16 is not installed, the amount of tap water consumed by the mist generator 18 is high, and if the calculated ratio is lower than the preset ratio, the cloud 11 (server) 16 and the mist generator 18 (or the output of the mist generator 18), the consumption (evaporation amount and spray amount) of tap water (tap water) in the cooling tower 16 and the mist generator 18 (the cooling tower 16 When the cooling tower 16 is stopped or the cooling tower 16 is not installed, the tap water consumption in the mist generator 18) and the power consumption in the cooling tower 16 and the mist generator 18 (when the cooling tower 16 is stopped or the cooling tower 16 is installed) If not, the power consumption in the mist generator 18) can be reduced, and the energy saving of the factory 30c (building) can be achieved.

FIG. 11 is a diagram showing another example of a factory 30d (building) in which the water rate management system 10 is installed. A cooling tower 16 (cooling tower) is installed on the roof of the factory 30d (building) shown in FIG. A large industrial dryer 19 (dryer) is installed indoors in the factory 30d (building). The cooling tower 16 is the same as that of the factory 30a (building) in FIG. In addition, in the factory 30d (building) shown in FIG. 11, the cooling tower 16 may not be installed, and only the large commercial dryer 19 (dryer) may be installed.

The large commercial dryer 19 (dryer) is installed indoors in the factory 30d and is used for drying clothing in the cleaning industry and linen in the linen supply industry. The large commercial dryer 19 evaporates moisture from clothing and linen items and exhausts steam to the outside, so it consumes (uses) a large amount of tap water (tap water). A wireless communication device (wireless LAN) (not shown) is connected to the control unit of the large commercial dryer 19. The control unit of the large commercial dryer 19 uses a wireless communication device (wireless LAN) to send an operation signal (including building specific information) or a stop signal (including building specific information) to the large commercial dryer 19. is transmitted to the communication equipment of the factory 30c, and the communication equipment sends the operation signal (including building identification information) or stop signal (including building identification information) of the large commercial dryer 19 to the cloud 11 (server) via the Internet. ).

The water usage amount measurement means, the water usage amount transmission means, the sewage drainage amount measurement means, the sewage drainage amount transmission means, the rainwater drainage amount measurement means, and the rainwater drainage amount transmission means implemented in the factory 30d in FIG. 11 are the same as those in the factory 30a in FIG. They are the same. The amount of water used is the amount of water used in the cooling tower 16 (equipment) and large commercial dryer 19 (equipment) (or large commercial dryer 19) for a specified period (one month, two months, etc.).

The charge calculation means, the second water charge storage means, the water charge difference calculation means, the water charge difference storage means, the ratio calculation means, and the ratio storage means are the same as those of the cloud 11 in the factory 30a of FIG. 3.

Sewage drainage amount (cumulative amount) excluding tap water (tap water) consumed (evaporated) in cooling tower 11 (equipment) and tap water (tap water) consumed (evaporated) in commercial large dryer 19 (equipment) ) is calculated from the second water charge for the amount of water used (accumulated amount), which includes the tap water consumed in the cooling tower 16 and the tap water (tap water) consumed in the commercial large dryer 19. is also cheap, so the water charge difference calculated by the water charge difference calculation means is negative. Note that even if the cooling tower 16 is stopped or only the large commercial dryer 19 is installed in the factory 30d, the tap water (vaporized) consumed (evaporated) in the large commercial dryer 19 is The first water charge for the amount of sewage discharged (accumulated amount) excluding water) is higher than the second water charge for the amount of clean water used (accumulated amount) including the tap water (tap water) consumed in the large commercial dryer 19. is also cheap, so the water charge difference calculated by the water charge difference calculation means is negative.

In the ratio calculation means, the cloud 11 (server) receives the operation signal of the cooling tower 16 from the communication equipment of the factory 30d (the control unit of the cooling tower 16), and receives the operation signal from the communication equipment of the factory 30c (the control unit of the large commercial dryer 19). When the operation signal of the large commercial dryer 19 is received (including the case where only the operating signal of the large commercial dryer 19 is received), the cooling tower 16 and the large commercial dryer 19 are not operated unless a stop signal is received. The amount of sewage discharged (integrated amount) measured by the sewage flow meter 12 (sewage flow meter The ratio of the sewage drainage amount (integrated amount) obtained by subtracting the rainwater drainage amount measured by the rainwater flow meter 14 from the sewage drainage amount (integrated amount) measured by 12 is calculated.
