The present invention relates to a regional water and sewage service evaluation system and method using GIS, and more specifically, to link the various water and sewage service related information collected and managed by region with GIS information, and more in the regional water and sewage service evaluation The present invention relates to a system and method for enabling the provision of objective and useful data.

The global water market is estimated to reach KRW 886 trillion in 2004, with annual growth rate of 5.5% and higher than global growth rate of 4.6%. Internally, due to the centralization of multinational water companies in France and Germany, less than 20 companies are expected to occupy more than 50% of the total market in 2015. Especially in China, more than 60% of water and sewage projects Multinational companies are participating, and in Southeast Asia, multinational companies such as Suez and RWE have a high market share.

Internationally, there is a message to include water and sewage services in WTO free trade targets, and the International Organization for Standardization (ISO) is pushing for international standardization of water and sewage services. Domestically, it provides opportunities for non-local companies to participate in water and sewage projects through amendments to the Water Act and Sewerage Act.However, the inclusion of water and sewage sectors in WTO free trade targets is temporarily reserved to reflect the domestic situation. It was.

On the other hand, the international standardization of water and sewage services begins with the proposal of France, which has Veolia, a leading company in the world water market, and aims to improve the quantity and quality of water and sewage through standards and standardization of service activities related to water and sewage system management. For this purpose, the definition of terms used in the standards, the establishment of standards related to consumer expectations, the establishment of standards related to water service, and the establishment of standards related to sewage services are carried out around 43 member countries and 4 organizations. have. If the water market is opened, the WTO requires that the world standards be applied if there is no domestic standard, so it may be used as an international standard for water and sewage services in Korea. In Korea, since 2002, a countermeasure meeting has been organized and measures for strengthening the competitiveness of water and sewage services have been studied.At present, a specialized committee was organized by the Ministry of Commerce, Industry and Energy's Technical Standards Institute. It is true.

However, as mentioned above, European countries with huge water companies are expected to gradually increase the pressure to open the water market by including water and sewage services in the WTO free trade target, so Korea is also actively responding to the opening of the international water market. In order to strengthen the international competitiveness of water supply and sewage service providers, it is urgently required to quickly establish Korean standards (indicators) reflecting the domestic situation.

In other words, if the opening of the water market is promoted due to international standardization, foreign companies are expected to enter the domestic market in the near future, and there will be an opportunity for change such as inducing competition between companies and demand for restructuring. Although there is a risk of pressure on consumers to provide higher quality services through transparency, objective comparison and evaluation of water supply business is possible based on standardized indicators, and transparency of water supply business is enhanced by disclosure of service activity indicators. It can also act as a positive factor such as enhancing technological competitiveness and efficiency through good competition, activating technology exchange between countries and increasing overseas market entry. Therefore, it is important to compensate for the lack of market formation and lack of countermeasures for enhancing competitiveness due to lack of market formation and to use it as an opportunity to enter the overseas market through changes in the management system of the water industry and systematic preparation and preparation.

However, if you look at the evaluation system of domestic water supply business, it is largely divided into local water supply and regional water supply. The main evaluation institutions and evaluation contents are as follows.

Evaluation system name Enforcement Institution Main Content Water Treatment Plant Assessment Ministry of Environment 54 waterworks: manpower, water quality management, operation management, maintenance, service Sewage Treatment Plant Operational Assessment Ministry of Environment 31 sewerage systems: administration, maintenance, sewage treatment plant operation management, sludge management, facility advancement Government Investment Agency Management Evaluation Planning and Budget Office Among the 100 evaluation criteria of government-funded institutions, only the water management business, human resource management, finance and budget management are valid evaluations. Local water and sewage project public enterprise evaluation Ministry of Government Administration and Home Affairs 21 waterworks, 19 sewerages: management, organizational management, financial management, facility operation and technology development, customer support, etc.

However, as the evaluation system is operated by an independent management body, the evaluation of such evaluation increases the inefficiency of the administrative work, and there are a lot of non-quantified indicators, so there is a concern that the objectivity is lowered and the subjectivity is involved in the evaluation. In addition, as the evaluation result is managed through software for editing documents such as Microsoft Excel, even if an index for water and sewage service evaluation is prepared, it is difficult to manage the history, and it is not easy for the service subjects to cross each other. It is not easy to evaluate in Korea, and it is not easy to reflect continuously changing environmental factors such as facility change and population movement.

The present invention was devised to solve the above problems, and standardizes water and sewage service evaluation data for each region, manages them by database, and efficiently manages the service evaluation using GIS (GIS, Geographic Information System). By linking regional information, facility information, underground facility management information, and population trend information among the necessary elements, it is possible to make evaluation based on more objective data and make decisions on selecting the optimal service subject. Through the analysis of the pattern of evaluation data and regional status data accumulated in time series, it is possible to support the function of regional business effect prediction system and regional water and sewage service comprehensive evaluation system that can be used for forecasting future water and sewage projects. By developing a system The purpose for the ball.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. Prior to this, terms or words used in the specification and claims should not be construed as having a conventional or dictionary meaning, and the inventors should properly explain the concept of terms in order to best explain their own invention. Based on the principle that can be defined, it should be interpreted as meaning and concept corresponding to the technical idea of the present invention.

Therefore, the embodiments described in the specification and the drawings shown in the drawings are only the most preferred embodiment of the present invention and do not represent all of the technical idea of the present invention, various modifications that can be replaced at the time of the present application It should be understood that there may be equivalents and variations.

1 is a diagram illustrating a network system configuration according to an embodiment of the present invention. Regional water and sewage service evaluation system using the GS according to the present invention is a GS database server 20 for storing the structural attribute data of water and sewage, an unstructured attribute data database server 30 for storing the unstructured attribute data of water and sewage, And a water and sewage service evaluation server 10 that calculates water and sewage service quality of a predetermined region by combining the data. The servers may be interconnected by LAN or WAN.

In the case of waterworks, the structural attribute data

Information such as pipe numbers, pipe diameters, installation dates, extensions, depths, materials, etc. in water intake pipes, water pipes, drain pipes, and water pipes as water supply pipe facilities; Information such as valve number, installation date, valve diameter, opening state, manufacturer, valve type, material, etc. in a water supply valve, a check valve, a pressure reducing valve, an air valve, an earth valve, and the like as a water supply control facility; Information such as a water intake, a water purification plant, a drainage station, a facility name in a pressurized plant, a location, an installation company, an installation date, a facility capacity, a power consumption, and a type of water supply facilities; Information such as control number, installation date, jurisdiction fire department, height, depth, diameter of fire hydrant as a fire extinguishing facility, water tower, etc .; Information such as control numbers, apertures, installation dates, addresses, elevations, and depths in the area flow meters and meters as measurement facilities; Refers to materials, including

Also in the case of sewerage,

Information such as name, location, land area, treatment capacity, sewage pump type and specification, sedimentation basin standard and capacity, sludge concentration tank standard and capacity, contractor, construction number, discharge swimming pool, opening status in sewage treatment facility; Information such as individual number, name, management institution, location, installation date, treatment capacity, pump station use, pumping capacity, facility specifications in sewage pumping station; Information such as individual number, stream name, stream number, stream water system, stream water, stream number, extension, euro extension, and basin area in the stream; Information on river maintenance history; Information such as individual number, management authority, feature code, width, extension, height in a river facility; Refers to materials, including

In addition, the water and sewage system also includes the construction number, construction name, construction location, construction classification, designation amount, estimated amount, contract date, start date, completion inspection date, project cost, contractor, total construction amount, subsidies, established amount, change frequency. , Including the amount of change, etc.

That is, the structural attribute data includes the structure of the water and sewage system and related information, and is largely computerized as a standardized GS data. Generally, the attribute data are constructed in the waterworks and sewage divisions, or subordinate construction safety. It is surveyed and collected at test establishments, facility management establishments, waterworks regional establishments, etc., and collected by relevant departments such as city halls, where it is stored and managed to form water and sewage layers according to GIS standards. Therefore, the structural attribute data is managed by the system of the business headquarters until the formation of the GS standard data, and if necessary, data necessary for water and sewage service evaluation may be obtained from the system of the headquarters. On the other hand, the structural attribute data are given for each pipeline.

For reference, the meaning that it is input and managed as GS data is as follows. The GS database server 20 included as a component of the system according to the present invention refers to a part of a database managed by a National Geographic Information System (NGIS), that is, a national geographic information system. The NGIS quantifies the spatial information of each area, such as digitizing the spatial information related to the ground and the ground of the entire national space into digital maps, and in national policy, administration, and public sectors such as disaster management, national space management, and civil service. It is a system that can be utilized efficiently. Therefore, NGIS includes various digital information such as various administrative information, roads, buildings, ports, topography, and answer information, and human information such as population number, age, population distribution, and movement. In addition, the above-mentioned digitized various kinds of geographic information do not have a limit in kind and range, and various additional information may be added as necessary.

In the case of water and sewage attribution data, when data is newly converted from the data collected by the business headquarters to meet the NGIS standard, the data is managed to be related to other geographic information. Currently, the Ministry of Construction and Transportation manages the national integrated geographic information database by the Ministry of Construction and Transportation, but the Ministry of Construction and Transportation does not manage all the input and management of information. When GS data of each layer constituting NGIS is generated, the Ministry of Construction and Transportation proceeds in the form of integrated management. In other words, the layers all come together to serve as national geographic information.

Therefore, as mentioned above, the method for acquiring attribute data of water and sewage by the regional water and sewage service evaluation system according to the present invention is obtained from the GS database server 20 on the NGIS, or in addition to the acquisition path. By connecting to the headquarters, etc., the necessary data can be obtained from the data not reflected on the NGIS. At this time, the additional attribute data can be easily obtained if there is a data extraction module from a database which can be easily prepared by a person skilled in the art and a LAN or WAN network that can access and connect to the database.

In addition, the GS database server 20 is a logical server concept constituting the system according to the present invention, and may be one or more servers physically, and as a subordinate concept, includes a database server in the business headquarters or the like. May be interpreted as. That is, NGIS does not necessarily store and manage all information in one physical server as long as the NGIS is a conceptual entity rather than a physical entity. Therefore, the system according to the present invention obtains predetermined data necessary for water and sewage service evaluation. To this end, a plurality of physical servers storing the geographic information may be freely interlocked according to the actual situation.

However, as mentioned above, in order to enable the system according to the present invention to perform an optimal function, it is most preferable that the data obtained are data stored and managed according to GS standards.

The non-structural attribute data of water and sewage refers to data related to water and sewage service policy and maintenance, in addition to the structural attribute data. Examples include data on service personnel, data on financial management to maintain services, and data on complaints. More specifically, items such as inspections for maintenance, service failures, water quality measurement, technical diagnosis, accidents, budget, asset size, sales, staff, and labor costs may be included. Such data are generally managed by the unstructured attribute data database server 30 by combining due diligence and reporting data, and as an example, the database may be located in a working department of a borough or a county. However, the details of the data may be changed according to the interpretation of the collecting subject.

The service evaluation server 10, based on the module for calculating the water and sewage service quality of a predetermined region by combining the above-described data and the service quality calculation result, the user selects a specific pipeline displayed on the GIS map. And a module for displaying detailed scores of each item of the evaluation index corresponding to the selected pipeline. In addition, according to the user's selection, further includes an input module for receiving a condition to be used for the evaluation. At this time, the service evaluation server 10 is previously stored evaluation criteria for water and sewage service evaluation, the evaluation criteria, as an embodiment, public health promotion, stable supply of services, persistence of water and sewage services, local It can be divided into areas such as sustainable development of society and minimization of environmental impact.

The service evaluation server 10 assigns a score to a detailed item on each area of the evaluation criteria to be described below based on the attribute data of water and sewage, and uses the score to determine each area or all areas. Collectively, the service quality of a given area is calculated. However, since the scores for each sub-item given in the above quality calculation process are derived based on standardized GS data such as structural attribute data of water and sewage, the scores of sub-items for specific pipelines on the GS map It can be displayed simultaneously on one screen (Fig. 2). In addition, the service evaluation server 10, in the evaluation of the service, which region to target, for which period to evaluate, such as I / I analysis, water quality analysis, irregular flow analysis, etc. In the case of being used for evaluation as a specific item, an input module may be provided to receive a user's selection regarding what time the analysis data will be used. However, it is obvious that the areas of the evaluation criteria may be changed according to the evaluator's interpretation.

And according to the embodiment, the service evaluation system according to the present invention can further configure the water and sewage service provider management database server 40, in which case the service evaluation server 10 is the information of the added database Should be further considered in estimating service quality. By the way, when the service provider management database server 40 is further comprised as mentioned above, when the construction company's construction history etc. of the service provider are not fully reflected in the GS database server 20 mentioned above, It is to be understood that the system is added for temporary operation in evaluating the service provider's business feasibility. Therefore, if the relevant information is sufficiently reinforced in the GS database server 20, the configuration may be omitted. The data of the service provider management database will be similar to the specific data of the construction details.

Hereinafter, a process of estimating water and sewage quality by a regional water and sewage service evaluation system using the GS of the present invention as described above, and a method of using GIS information in the process will be described. Although the service evaluation of water and sewage will be integrated and explained, it is obvious that water service evaluation and sewage service evaluation can be performed separately.

3 to 11 are flowcharts of a water and sewage service evaluation method for each region according to an embodiment of the present invention and a configuration diagram of a related screen.

First, the user selects a region for which service evaluation is desired (S101), and if the conditions of evaluation criteria, such as the above-described interpretation data that the user wants to set arbitrarily, are specified (S103 and S105), the service evaluation server 10 inputs them. Accepted via the module (see FIGS. 4 and 5). The region may be singular or two or more plural and may be selected based on the divisions in the administrative district. As mentioned above, in one embodiment of the present invention, five areas including public health promotion are illustrated as water and sewage service evaluation criteria, but the quality of service may be evaluated in all five areas, In the case where the quality of service in one or more regions is evaluated, a function of selecting and inputting some of the regions may be added to the input module.

When the input of the above conditions is completed, the service evaluation server 10 obtains structural and unstructured attribute data of water and sewage from the GS database server 20 and the unstructured attribute data database server 30 according to the selected evaluation criteria. It is made (S201). The service evaluation server 10 may further include a separate database to preserve the data obtained through the acquisition process. The data obtained as described above is used to calculate a service quality through a process (S203) that is scored based on the following items. For reference, the following evaluation items are explained based on the items used as indicators in water and sewage service evaluation internationally.

As mentioned above, the public health promotion, stable supply of services, sustainability of water service, sustainable development of community, and minimum impact on the environment as the evaluation criteria mentioned above are divided into detailed criteria as shown in the table below. Can be.

In other words, the collected property data of water and sewage are used to score the degree to which the above detailed criteria are achieved. Specifically, the above detailed criteria are again divided into detailed evaluation indicators and variables, which are variables for calculating the scoring. For example, detailed evaluation indexes and variables corresponding to public health promotion areas in the water service evaluation among the evaluation criteria are as shown in the following table.

Therefore, when the variable items in the table are scored based on the water supply attribute data, the numerical data in estimating the quality of service of the water service in the region are formed. In the same way, detailed evaluation indicators in other areas are scored, except that the specific variables in the other areas should be based on international standards already used in foreign countries. Therefore, it is possible to change according to the situation of the country, and also because the distance from the technical features of the present invention will not be described further.

When the scoring of all the evaluation indicators is completed by the above process, the average score is calculated by summing the scores for each item in each evaluation standard area (S301), and based on the average score, each area or total evaluation Water and sewage service grade for each standard is determined (see FIGS. 6 and 7, S501). In this case, the service grade may be simply converted by mapping the average score to a grade in an arbitrary range set by the user, or the average score may be used as it is.

Meanwhile, the method of calculating the service quality by summing and averaging the scores of the respective evaluation indicators is exemplified, but a method of calculating the service quality by assigning an additional point is also possible. That is, when the scoring of the evaluation index is completed as described above, using the characteristic that the structural attribute data of the water and sewage system is assigned to each conduit, the score is pre-set by the user for each conduit (for example, 1 to 10 grade (S401), and by adding the points according to the grade set by the user for each conduit (S403), by using the average score (S405) derived from the score given the addition point To determine the service level as above. In addition to these methods, the user can obtain different service evaluation results by modifying the scores of the evaluation indicators according to which indicators the user wants to place in the evaluation (see FIG. 8).

The service grade determined as described above may be used as basic data in calculating the service improvement efficiency of the water and sewage service provider (S601). Water and sewage attribute data in the present invention is a standardized GS database data, it is possible to manage the time series history of the water and sewage service status from the past to the present. Therefore, it is possible to evaluate how efficient the service improvement was achieved in each region by comparing the existing construction details and service evaluation grades before and after the construction for any particular water and sewage service provider. Do. In detail, the above evaluation includes evaluation by means of unit-by-unit analysis, such as how the degree of deterioration of the pipeline in the region is improved or the amount of inflow water is improved through a certain cost of construction (see FIG. 9). Such data can be used as decision-making data to compare service superiority between current water and sewage service providers, and to select a service provider most suitable for the purpose of the project when a service provider must be selected for a new business in the future. .

In addition, the water and sewage service grade can serve as the data necessary to determine how to utilize the limited resources in each region. That is, in the same principle as that of calculating the service improvement efficiency of the water and sewage service provider (S601), the history of past expenditure is obtained by referring to the past project cost expenditure history and the service grade before and after the project among the GIS data being managed by the history. Since it is possible to systematically display (S701) which service grade improvement has been brought to the user (see FIG. 10), on the contrary, it is possible to predict how to distribute the current resources to achieve the desired business purpose. It can be used as evidence to help users make decisions (see Figure 11).

As mentioned above, although this invention was demonstrated by the limited embodiment and drawing, this invention is not limited by this, The person of ordinary skill in the art to which this invention belongs, Of course, various modifications and variations are possible within the scope of equivalent claims.

As described above, according to the present invention, in the case of the existing method, the progress data were separated and evaluated by determining whether the regional unit to which the regional water and sewage service evaluation was applied was a regional municipality, a basic local government, a district unit, or a block unit. The establishment of GIS-based system ensures the connection of relevant data, and enables immediate calculation without any change or separate work of the evaluation area unit.In order to conduct water and sewage service evaluation, public health promotion, service stability, service Consideration should be given to sustainability, local conditions, and the environment, and data on countless causes that determine each evaluation indicator can be obtained on the basis of GS, so that the evaluation can be performed on the basis of more immediate, accurate, and compatible data. It is possible to do

In addition, water and sewage service evaluation can be divided into facilities, resources, management, and manpower status.In order to calculate the comprehensive water and sewage service evaluation, data such as regional information, facility information, underground facility management, and population trends are required. By securing through GIS, evaluation is possible according to the local situation of the evaluation area, and the evaluation indicators and facility changes (economic indicators, population changes, social changes) through the management of facilities history on GIS at the time of pre- and post-project evaluation. Merging and reviewing indicator changes can provide more reliable results. In addition, it is possible to predict the business effect by analyzing the change patterns before and after the service improvement of GIS data.

Therefore, the efficiency of resource allocation, such as the central government's manpower and budget, can be strengthened, and goodwill competition is encouraged by region by streamlining administrative and financial support for improvement of regional sewage services, such as improving service dissatisfaction areas and introducing excellent service projects. This can contribute to the institutionalization of service improvement and the strengthening of administrative responsibility.
