The first method is preventive repair and salvage repair according to the priority of repair time.

Preventive repair: a city needs to reasonably plan and manage the underground pipelines and these fixed assets, including the laying year, main pipe diameters, geographical location, regional development planning (government location, core residential areas, major commercial areas, important industrial areas, etc.), as well as the status of underground surrounding pipelines, operation status, operation and maintenance records, resident complaint rate and other information, plan in advance, and lay out the repair plan and budget in advance, Repair according to priority.

Salvage repair: the underground pipe network system transports a large amount of sewage into the treatment plant every day. Ground dynamic loads such as large trucks will cause fatal damage to the underground pipe network. Especially in the thunderstorm season, a large amount of rainwater enters the drainage pipeline, causing an unknown risk of a pipeline rupture. Therefore, salvage repair may be required anytime, anywhere.
