[Excerpt from the report].
Promote the management of leakage in the public water supply network, and reconstruct 93 kilometers of water supply pipe network.
In the urban water supply system, the leakage problem will not only lead to the waste of water resources, but also increase the cost of water supply and affect the safety of water supply.
Since the start of construction in July 2022, Jinan Water Group has continued to promote the leakage control project, of which the 2022-2023 Jinan Public Water Supply Network Leakage Control Project involves 28 municipal roads. "At present, the leakage rate of the water supply network in Jinan urban area is 916%, with plans to drop to around 8% by the end of the year and below 7% by 2025. Previously, Chen Feng, deputy general manager of Jinan Water Group, introduced that in 2023, 21 areas in Jinan City, including Chengfei Dormitory Community, Yuhan Community South District, and Baima Garden South District, will successfully complete the leakage control and transformation, and complete the pipeline transformation 59 kilometers, with a completed investment of about 61.23 million yuan.
It is understood that 23 old municipal roads such as Dawei 2nd Road, Hero Mountain Road, Shanda South Road and Normal Road have entered the construction site in Jinan City, and 11 have been completed; Completed the renovation of water supply pipelines227 kilometers, with a completed investment of about 162.81 million yuan. "We have successively built an intelligent production scheduling system, a large-scale leakage control system, a DMA partition intelligent management system, a group version of the GIS system, a smart pipe network management system, a smart secondary water supply management system, a smart water quality management system, a smart marketing management system, an Internet of Things management system, a direct drinking water marketing system, and upgraded the first-class service system and intelligent work order management system. Tian Lei, project administrator of Jinan Water Group, introduced.
It is worth noting that Jinan Water Group plans to build 688 new DMA zones. According to the new DMA partition, the amount of water leakage will be reduced by about 0290,000 cubic meters per year,** can reduce the amount of water leakage by about 1.99 million cubic meters per year. In December 2022, the General Office of the National Development and Reform Commission and the General Office of the Ministry of Housing and Urban-Rural Development jointly issued the Notice on the List of Key Cities (Counties) for Public Water Supply Network Leakage Control, and Jinan City was successfully selected into the list of key cities for public water supply network leakage control in the country.
Jinan's "14th Five-Year Plan" for Water Development clearly points out that Jinan will strengthen the control of water supply leakage, accelerate the transformation and upgrading of urban water supply pipe networks, update and transform water supply pipe networks with a service life of more than 30 years and backward materials, and promote the transformation and professional management of secondary water supply facilities. By 2025, the leakage rate of Jinan's urban water supply network will be reduced to 78 or less.
