Advanced construction technology, good operation and maintenance, and timely pipeline repairs are essential for establishing a ‘full life-cycle management’ system for drainage pipelines. This is the key to extending the pipeline lifespan and improving the investment returns of pipeline networks. It can enhance drainage management performance and improve the city's environmental protection capabilities.

Currently, the pipeline inspection and repair technologies are developing rapidly, including various techniques such as CCTV robots, sonar, radar, and pipeline electrical methods. Pipeline repair technologies encompass a range of processes, including fold-and-deform methods, thermal pull methods, cold pull methods, in-situ resin curing, and steel sleeve techniques.

• Development of materials and techniques for the repair of reinforced concrete drainage pipelines

• Research and development of new pipeline construction techinologies

• Standardized testing research of pipeline network repair materials

• Research on integrated asset management systems fot municipal and community pipeline networks

• Sustainable maintencance of municipal drainage systems

• Cleaning and unlogging of drainage pipelines
