In recent years, the Tap Water Company of the City Development Group has consistently prioritized "water conservation, reduced losses, and public benefit" as its core mission. Through scientific management and precise control, the company has not only met the national target for controlling water supply pipeline leakage ahead of schedule but has also tangibly improved the water usage experience for residents. By the end of 2024, the leakage rate in the public water supply network of Tangshan's central urban area had been reduced from 9.75% in 2021 to 6.31%, achieving the national requirement of "controlling the leakage rate within 7% by the end of 2025" one year early. This represents a remarkable achievement in public welfare.
Impressive results have been achieved through multiple breakthroughs in reducing water loss. At the Tap Water Company, Guo Baojiang, Deputy Party Secretary and Deputy General Manager, highlighted statistical charts showing the non-revenue water rate, noting that it has steadily decreased from 17.92% in 2021 to 13.27% in 2025. This success is attributed to precise efforts across the entire management chain. In terms of infrastructure, the company invested over 18 million yuan to establish 687 district metering areas (DMAs), achieving full coverage of metering in residential communities. On the management front, more than 5,000 leak repairs were completed over five years, with a commitment to stopping water flow within 30 minutes, ensuring network stability. Additionally, over 2,800 cases of unauthorized water use were addressed, recovering more than 8 million yuan in water fees, which both upheld water supply秩序 and prevented compliant users from bearing undue costs.
The reduction in water loss is not merely a numerical improvement but translates into a more stable, economical, and reliable water supply for residents. Upgrades to aging pipeline networks in older communities have reduced issues such as unstable water pressure and leaks, alleviating concerns about frequent water interruptions. Annual inspections of main pipelines and dynamic leak detection in communities help identify hidden leaks early, enhancing water quality safety. Designated inspections of fire hydrants and metered ecological water use via IC cards ensure emergency water supply security and standardized urban greening practices, indirectly improving the living environment.
Reflecting on the governance experience, Guo Baojiang summarized it with three key elements: scientific strategies, institutional safeguards, and innovation-driven approaches. Scientific strategy involves data analysis to identify control priorities, implementing tailored solutions for high-leakage areas, and synchronizing the renovation of old pipelines with DMA establishment. Institutional safeguards include monthly meetings to oversee progress, with weekly and monthly summaries ensuring that dozens of specific measures are assigned across departments for accountability. Innovation is highlighted by the company's development of a "multi-angle analytical algorithm" for precise leak detection, with five governance measures being included in the Ministry of Housing and Urban-Rural Development's list of replicable policies for nationwide promotion.
Looking ahead, the Tap Water Company of the City Development Group will continue to strengthen long-term mechanisms for leakage control, ensuring that the benefits of water conservation and efficiency reach more residents and further securing urban water supply safety.
