The renovation of underground pipelines is an important part of the city's renewal this year.
Currently, various regions are continuously speeding up the renovation process, and various new technologies and methods are widely used, driving the continuous upgrading of underground pipeline network renovation technology and further expanding the market size.
From a national perspective, at the current pace of renovation, China will transform underground pipelines of more than 100,000 kilometers every year. In particular, this year, as prefecture-level cities and above carry out comprehensive urban medical examinations, pipeline network problems discovered during medical examinations will be resolved at an accelerated pace, involving various industries such as design, construction, materials, equipment, and monitoring and maintenance.
According to preliminary estimates, during the “14th Five-Year Plan” period, the country's underground pipeline network renovation investment will exceed trillion dollars, and the industry has broad prospects for development.
The National Development and Reform Commission and other departments issued major achievements on comprehensively consolidating the prevention and control of the epidemic. Among them, the improvement of environmental infrastructure is being accelerated. Make up for shortcomings in domestic sewage collection and treatment facilities.
In 2022, the Development and Reform Commission issued a notice on the “14th Five-Year Plan” implementation plan for new urbanization. The notice states that pipeline network renewal and underground pipe gallery construction will be promoted.
Guide all regions to collaborate to promote pipe gallery construction according to local conditions in the renewal and renovation of old urban pipeline networks, etc., actively develop trunk and branch line pipe galleries in new urban areas according to functional requirements, rationally lay out pipe gallery systems, and coordinate the laying of various types of pipelines.
Expedite the clarification of the fee policy for entering the gallery, and take more measures to resolve the problem of blocked investment and financing. Do a good job of coordination, optimize the project space layout, arrange the construction schedule reasonably, and avoid repeated excavation. Improve the normalized management mechanism for municipal public facilities to ensure the stable and safe operation of facilities.
By 2025, 45,000 kilometers of sewage collection networks will be added and renovated to basically eliminate dark and smelly urban water bodies, and increase the domestic sewage treatment rate in rural areas to 40%.
