Water transportation planning device, method, program, recording medium, and server therefor

Abstract

PROBLEM TO BE SOLVED: To make a water operation plan for minimizing cost for water transportation and water treatment in water supply facility for taking water from a plurality of water sources having different water quality.

SOLUTION: The water operation plan for the water supply facility is made by a water operation planning device 1 provided with a water transportation cost computing means for computing water transportation cost in the water supply facility 6 when taking water from each water source 7A, 7B including cost for purchasing raw water and a water transportation amount planned value computing means for computing a planned value of water transportation amount in the water supply facility 6 based on the water transportation cost computed by the water transportation cost computing means.

Description

technical field [0001] The present invention relates to a device or method for drawing up a water utilization plan for a water supply pipeline facility that draws water from a plurality of water sources. Background technique [0002] Water piping facilities play an important role in the stable supply of safe water. Raw water taken from surface water (rivers, reservoirs, lakes, etc.), groundwater, underground river water, etc., is treated in the water purification plant to remove pollutants and harmful substances, and is sent to the grassroots through the water distribution tank or water distribution pipe network Supply to those in need. In water pipeline facilities, generally speaking, water is drawn from multiple water sources, there are multiple water distribution pipe networks or multiple water treatment systems, and there are also multiple water distribution tanks, and the water distribution pipe networks are distributed in a wide area. And through the computer system ...

Problems solved by technology

[0012] The technique described in JP-A-11-203268 (Patent Document 2) targets multiple wells or water distribution tanks, and simulates only the amount of water intake and distribution flow, and calculates the amount of electricity or chemicals related to water treatment, etc. The cost of the

In addition, since only clean well water is used as the object, it cannot be applied to the water intake plan of the water purification plant with water sources with fluctuating water quality.

[0013] In the technology described in Japanese Patent Laid-Open No. 8-128078 (Patent Document 3), consumption resources per unit flow rate (yen/m 3 ) to calculate the cost of clean water generation, and cannot calculate the change in the amount of chemicals or electricity for water treatment when the water quality changes

Therefore, there is a problem that it is not possible to reflect changes in the quality of raw water in the production cost of purified water.

In addition, when planning the intake of water from a plurality of water sources with different water quality, there is a problem that the intake of each water source cannot be obtained appropriately

Furthermore, there is a problem that the cost cannot be calculated when there are multiple water treatment systems with different styles in the water purification plant.

Moreover, the
