T/GERS 0016-2023 Specifications for the Retroactive Compensation of Water Volume Due to Inaccurate Water Metering in Water Supply Systems

Scope

Main technical content: This standard is drafted in accordance with the provisions of GB/T 1.1—2020. The relevant content has been verified and is highly operable and scientific. Based on the survey and opinion collection, the main technical content of the standard is determined as follows: 1. Clarify the relevant terms and definitions of water supply metering inaccuracies and water volume compensation, including water volume metering devices, water volume metering errors, water supply metering inaccuracies, error values, reference water volumes during inaccuracies, and compensation water volumes. 2. Clarify the categories of metering inaccuracies, including two main categories: water volume metering errors and water volume metering mistakes, each of which is divided into several sub-categories. 3. Clarify the method of determining compensation water volumes. First, clarify the method of determining error values; then clarify the determination of reference water volumes during inaccuracies, including the determination of reference water volumes under water volume metering errors and three types of water volume metering mistakes, namely “water volume metering device failure”, “water volume metering device parameter setting errors”, and “data recording, collection, transmission, storage, processing, or calculation errors”; finally, clarify the calculation method of compensation water volumes, including direct calculation, reference calculation, and comparison calculation. 4. Clarify the requirements for compensation of metering inaccuracies, including requirements for both water supply and water users. 5. To help water supply and water users better understand and apply this standard, five examples of compensation water volume calculation for water supply metering inaccuracies are listed in Appendix A.
