Description

Technical Field

[0001] This invention belongs to the field of water supply engineering technology, specifically relating to a comprehensive solution for leakage control in the water supply industry. Background Technology

[0002] With the continuous expansion of urban water supply networks, factors such as the increasing age of the networks, uneven construction quality, changes in the geological environment, and external damage have led to network leakage becoming a common pain point in the water supply industry. There is a significant difference between the daily water production and output of water plants and the actual water received by end users. This difference is defined in the industry as the production-sales gap, which directly corresponds to the amount of water lost from the network. This not only results in a large waste of water resources but also increases the water production costs, energy consumption, and operational burden on water supply companies, while simultaneously affecting water supply safety and the stability of water supply services.

[0003] Currently, most water companies, water supply companies, and water utilities in the industry only carry out sporadic leakage handling work such as routine leak detection, localized repairs, and basic metering verification, lacking a systematic, full-process, closed-loop leakage management system. For complex scenarios such as difficult leakage points in the pipeline network, concentrated leakage in aging pipelines, and areas with high production and sales differences, existing conventional methods cannot achieve effective management. Some water supply companies supply 100,000 cubic meters of water per day, but the actual water sales volume is only 50,000 to 80,000 cubic meters, resulting in persistently high leakage rates that are difficult to meet industry control standards.

[0004] Existing leakage-related technologies mostly consist of single leak detection devices, localized repair methods, and simple metering and calibration tools. They lack a comprehensive solution covering current situation diagnosis, business streamlining, zoning management, leak detection pipe probing, metering investigation, and effect monitoring. This fragmented application of technology results in short-term treatment effects and superficial problem-solving. Furthermore, the water supply industry has long lacked standardized, systematic, and comprehensive solutions protected by patents. Third-party professional treatment organizations lack patented technical support, leading to inconsistent treatment levels across the industry and making it difficult to fundamentally solve the problems of excessive production-to-sales ratios and pipeline leakage. Therefore, developing a comprehensive, end-to-end, implementable, and patent-protected solution for water supply industry leakage treatment has become an urgent technical challenge in this field. Summary of the Invention

[0005] In view of this, the present invention provides a comprehensive solution for leakage control in the water supply industry, in order to solve or alleviate one of the technical problems existing in the prior art, and at least provide a beneficial option.

[0006] The technical solution of this invention is implemented as follows: a comprehensive solution for leakage control in the water supply industry, including six core links throughout the entire process: diagnosis of the current status of the water supply system, streamlining of the entire business process, zoned metering management of the pipeline network, multi-dimensional leak detection and pipe probing operations, comprehensive investigation of metering instruments, and closed-loop monitoring of leakage control effects. The water supply system status diagnosis is used to collect comprehensive data on the daily water supply of water plants, the actual water received by users, and the operating parameters of the pipeline network. It calculates the total production and sales difference and the production and sales difference rate, and accurately identifies high-risk leakage areas, common leakage areas, and difficult leakage points, providing complete data support for subsequent treatment. The aforementioned comprehensive business process streamlining standardizes, integrates, and optimizes all aspects of water supply companies' operations, including meter reading, metering, operation and maintenance, leak detection, repair, and data reporting, eliminating management loopholes and hidden losses and production-sales discrepancies caused by human error. The pipeline zoning metering management divides the water supply network into several independent metering areas (DMAs). Each area is equipped with dedicated flow and pressure monitoring equipment to collect and upload data in real time. The minimum flow monitoring accuracy at night is ≤0.5m³ / h. By comparing regional data, the area where leakage occurs can be quickly located, greatly reducing the scope of leak detection operations. The multi-dimensional leak detection pipeline operation employs a comprehensive set of technologies including acoustic leak detection, correlation analysis, pipeline detection, and trenchless mapping. Core equipment includes a Fuji leak correlator, an LDR-20C electronic leak detector, an LSVP2000MM listening rod, a gas receiver, a PL-960 pipeline instrument, and a Bosch 7kg electric hammer drill. It is specifically designed for precise location and visual identification of difficult-to-detect leaks, hidden leaks, and leaks in aging pipelines, with a location error ≤ ±1 meter and a leak identification accuracy rate ≥ 97%. The comprehensive inspection of the metering instruments covered all water meters, flow meters, and metering instruments in the pipeline network, completing the entire process of error detection, accuracy calibration, fault replacement, and ledger update. The calibration accuracy met the CJJ92-2016 standard, completely eliminating the deviation in production and sales difference calculation caused by metering equipment problems. The closed-loop monitoring of leakage control effectiveness establishes a long-term data tracking and dynamic optimization mechanism after control, continuously monitoring the changing trends of water supply, water sales, leakage rate, and production-to-sales ratio to ensure the long-term stability and controllability of control results; and achieving phased and sustainable reduction of production-to-sales ratio for different initial levels. For regions with an initial production-to-sales margin of ≥20%, the margin will be steadily reduced to the range of 10% to 12%. For regions where the initial production-sales margin was between 10% and 15%, it was stabilized and reduced to below 10%. For regions where the production-sales gap has already fallen below 10%, while maintaining stability, the gap will be steadily reduced by about 0.5 to 1 percentage point each year to achieve long-term and continuous decline and refined management of the production-sales gap.

[0007] Furthermore, the proposed solution adopts a third-party full-process professional intervention model, which involves the entire process of leakage control for water supply companies, completely replacing the inefficient traditional method of scattered daily leak detection and partial repair. The third-party intervention includes current data collection and analysis, business process optimization and design, pipeline zoning plan formulation, leak detection and pipe probing operations, comprehensive rectification of metering equipment, and evaluation and feedback of treatment effects, forming a seamless, comprehensive, and closed-loop leakage treatment service system to ensure that the treatment effect meets the standards and is stable in the long term.

[0008] Furthermore, the production-sales difference calculation and leakage identification method uses the daily water supply of the water plant as the input value and the actual water received by the user as the output value. It accurately calculates the total production-sales difference and the production-sales difference rate through the difference between the two, and marks the areas with excessive production-sales difference rate in three levels to distinguish between regular leakage areas, high leakage areas, and difficult leakage areas. For areas with difficult leaks, a multi-technology cross-verification method is used to pinpoint the location of the leak, avoiding misjudgment or missed detection problems caused by a single leak detection technology. The leak point confirmation accuracy rate is ≥96%, improving the leak identification accuracy and positioning precision.

[0009] Furthermore, the pipeline network zoning metering management adopts a multi-level zoning architecture, dividing independent metering areas (DMAs) step by step from the main pipeline at the water plant outlet, the branch pipelines in the area, and the pipeline network of end users. The number of DMA branch pipelines is controlled between 1,000 and 2,500. Each area is independently equipped with metering and monitoring equipment, and uploads relevant data on flow, pressure, and leakage in real time. Through platform-based analysis, leakage areas can be quickly located, narrowing the scope of leak detection from the entire area to specific areas, which greatly improves the efficiency of finding and treating difficult leakage points.

[0010] Furthermore, the multi-dimensional leak detection pipeline operation is specifically designed for difficult and complex leak points in pipeline networks. It adopts trenchless integrated detection technology, complies with the CJJ61-2017 detection standard, and combines acoustic signal analysis, medium transmission characteristic detection, and precise pipeline location mapping to achieve non-destructive location of hidden leak points in underground pipeline networks, damaged points in old pipeline networks, and leak points in complex working conditions. It is suitable for various difficult and challenging treatment scenarios such as urban main roads, residential areas, and old urban areas.

[0011] Furthermore, the comprehensive inspection of measuring instruments is a full-coverage, no-blind-spot, and end-to-end operation, covering all large-diameter and small-diameter measuring equipment in the pipeline network. It includes static error detection, dynamic accuracy calibration, fault diagnosis and repair, replacement of unqualified equipment, and unified ledger updates, thoroughly solving the production and sales discrepancy problem caused by aging measuring equipment, decreased accuracy, non-standard installation, and data distortion, ensuring the accuracy of leakage control from the data source.

[0012] Furthermore, the comprehensive business process review covers all operational aspects of water supply companies related to leakage, and standardizes and regulates meter reading cycles, meter reading accuracy, data reporting timeliness, repair response speed (≤2 hours), daily leak detection frequency, and pipeline maintenance standards. It establishes a clear hierarchical leakage control responsibility system to minimize hidden leakage and increased production-sales gap caused by human factors and management loopholes.

[0013] Furthermore, the closed-loop monitoring of leakage control effectiveness is a long-term and continuous monitoring mechanism. After the control is completed, the service is not terminated. Instead, a monthly, quarterly, and annual data collection and analysis mechanism is established to compare the water supply, water sales, leakage rate, and production-sales difference rate after control with the data before control in all dimensions, forming a complete control effectiveness evaluation report. Control strategies are dynamically adjusted for areas that do not meet the standards. Through monthly, quarterly, and annual data comparisons, a virtuous cycle of "stability-consolidation-further reduction" is formed to achieve continuous optimization and long-term steady reduction of leakage control.

[0014] Furthermore, the proposed solution is specifically applicable to various water supply entities, including water companies, water utilities, and water groups. It addresses four major industry challenges that existing technologies cannot effectively handle: high production-to-sales ratio, difficult-to-handle leakage, systemic leakage, and leakage from aging pipe networks. Through comprehensive, systematic, and professional management, it simultaneously achieves multiple technical benefits, including water conservation, reduced production-to-sales ratio, improved water supply efficiency, and guaranteed water supply security.

[0015] The embodiments of the present invention have the following advantages due to the adoption of the above technical solutions: 1. Strong systemic governance: Breaking through the limitations of existing single leak detection and partial repair technologies, it constructs a full-process, closed-loop, integrated governance system that can thoroughly solve complex problems such as high production and sales gaps and difficult leaks.

[0016] Significant loss reduction effect: This invention can quickly reduce the production and sales difference rate, greatly reduce water resource loss, and the leak point identification accuracy rate is ≥97%, with a positioning error of ≤±1 meter.

[0017] Wide range of applications: Applicable to all water companies, water supply companies, and water groups, it can handle various scenarios such as old pipe networks, newly built pipe networks, complex pipe networks, and difficult leakage, and meets the requirements of CJJ92-2016 and CJJ61-2017 standards.

[0018] Improved operational efficiency: Reduces water production and operation costs for water supply companies, increases water sales revenue, and achieves a dual improvement in economic and social benefits. The production-sales gap rate is reduced by ≥20 percentage points after treatment.

[0019] Management level upgrade: Standardize the entire business process of leakage control for water supply enterprises, realize the digitalization, precision and standardization of leakage management, and achieve the minimum flow monitoring accuracy of DMA zones ≤0.5m³ / h.

[0020] The patents are of outstanding value: they fill industry gaps, form complete technical solutions, and provide core technical support for third-party leakage control.

[0021] Long-term and stable governance: The closed-loop monitoring mechanism ensures the long-term maintenance of governance effects, avoids leakage and rebound, and achieves sustainable leakage control.

[0027] Example 1: Leakage Control by a City Water Group A city water utility's water plant supplies 100,000 cubic meters of water daily, but users only receive 70,000 cubic meters, resulting in a 30% production-to-sales gap. The pipeline network has multiple problematic leak points, and conventional leak detection and repair methods are ineffective in reducing the leakage rate. This invention's comprehensive solution is used for remediation: 1. Current situation diagnosis: Collect water supply and sales data and pipeline parameters to identify 3 high-risk leakage areas and 8 difficult leakage points; 2. Business Streamlining: Standardize meter reading, operation and maintenance, repair, and data reporting processes, and establish a responsibility system for loss control; 3. Zoning Management: The pipeline network is divided into 12 independent metering zones (DMAs), and real-time flow and pressure monitoring equipment is installed. The minimum flow monitoring accuracy at night is ≤0.5 m³ / h. 4. Leak Detection Tube: Employing a combination of Japanese Fuji correlator, LDR-20C electronic leak detector, and LSVP2000MM listening rod technology, it accurately locates and repairs 8 difficult leak points with a positioning error of ≤±0.8 meters and an identification accuracy rate of ≥98%. 5. Metering inspection: All 326 water meters were fully calibrated, 126 metering devices with excessive errors were replaced, and the calibration accuracy met the CJJ92-2016 standard; 6. Closed-loop monitoring: After treatment, continuous monitoring for 6 months showed that the actual water received increased to 92,000 cubic meters, and the production-sales gap rate decreased from 30% to 8%, a reduction of 22 percentage points. Subsequently, the project entered a long-term stable control phase. While maintaining the production-sales gap rate within 8%, the project continued to steadily reduce it according to the annual plan, achieving a complete closed loop from "significantly reducing the gap" to "long-term stable reduction".

[0028] Example 2: Leakage Control by a County-Level Water Supply Company A county-level water supply company's water plant has a daily water supply capacity of 50,000 cubic meters, while users actually receive 25,000 cubic meters. The pipeline network is severely aging with numerous hidden leaks, and conventional methods have proven ineffective. The comprehensive solution of this invention was adopted for treatment: 1. Current Status Diagnosis: Calculate the production and sales difference, identify concentrated leakage areas in the old pipeline network, and mark 15 difficult-to-find hidden leakage points; 2. Business Streamlining: Optimize metering management and maintenance response mechanisms, ensuring a response time of ≤1.5 hours, and eliminating hidden losses caused by management loopholes; 3. Zonal Management: Divide the area into 8 independent metering and monitoring zones (DMA), with the number of branch pipes controlled within 1,500, to achieve regional leakage location; 4. Leak detection tubes: Using trenchless integrated detection technology (including gas receiver and pipeline instrument PL-960), 15 hidden leaks were located and repaired, with a 100% accuracy rate in leak point confirmation; 5. Metrological inspection: 315 measuring instruments were fully calibrated, and 213 unqualified devices were replaced, meeting the CJJ61-2017 detection standard; 6. Closed-loop monitoring: After treatment, continuous monitoring showed that the actual water volume received increased to 41,000 cubic meters, and the production-sales gap rate dropped to 18%, a decrease of 32 percentage points, completely solving the problem of high production-sales gap.

[0029] Example 3: Leakage Control of a Water Supply Company in a Development Zone A water plant of a water supply company in a development zone has a daily water supply capacity of 80,000 cubic meters, but users actually receive 48,000 cubic meters, resulting in both leakage due to construction work and metering discrepancies. The comprehensive solution of this invention is used to address these issues: 1. Current situation diagnosis: It was determined that the excessive production-sales gap was caused by both leakage and measurement factors, and 11 construction defects and leakage points were identified; 2. Business Streamlining: Standardize data reporting and operation procedures, ensuring work order upload time is ≤0.5 hours, and improve management standardization. 3. Zonal Management: Establish 10 metering and monitoring zones (DMA) to monitor flow and pressure data in real time, with a minimum flow monitoring accuracy of ≤0.3 m³ / h; 4. Leak detection tubes: Using integrated technology, 11 leaks left over from construction were located and repaired, with a positioning error of <±0.9 meters using a correlator; 5. Metrological Inspection: 158 non-compliant metrological devices were completely upgraded and replaced, and all instruments were calibrated, achieving a 100% accuracy compliance rate. 6. Closed-loop monitoring: After treatment, the actual water volume reached 70,000 cubic meters, and the production-sales difference rate dropped to 12.5%, a decrease of 27.5 percentage points, achieving dual optimization of leakage and metering.
