[Asia Economy Reporter Jongil Park] Gwanak-gu (Mayor Park Junhee) will conduct a comprehensive inspection of defective manholes starting in May and complete maintenance by December.

This is to prevent accidents caused by vehicles hitting defective manholes or sudden deceleration while driving on the road, and to resolve residents' inconveniences such as noise from defective manhole covers and pedestrian traffic hazards.

To create a safe road environment, the district has regularly inspected manholes installed on local roads and maintained about 100 defective manholes annually. This year, maintenance will be carried out by assigning four safety grades from ‘Ga’ to ‘Ra’ based on manhole functionality and degree of aging.

The main inspection items include visible cracks or damage on the cover, surface wear condition, height difference between the cover and frame, and height difference between the cover and surrounding pavement.

With a total project cost of 150 million KRW, the plan is to inspect 1,000 manholes in the area, prioritizing maintenance starting with ‘Ra’ grade manholes that require immediate action, aiming to repair a total of 79 defective manholes.

The ‘Ra’ grade, which requires early maintenance, refers to manholes with poor internal and external conditions needing urgent repair, such as those with a height difference of 10 mm or more between the cover surface and pavement surface, prioritized for emergency maintenance.

‘Da’ grade manholes, targeted for maintenance in the next plan, will be repaired within the budget, and ‘Na’ grade manholes with good functionality will also be continuously managed.

Mayor Park Junhee said, “If defective manholes are neglected, they can lead to serious accidents for pedestrians and drivers, so we are conducting a comprehensive maintenance as a proactive preventive measure. We will continue to do our best to prevent safety accidents through regular maintenance and systematic management of manholes in the area, creating pedestrian-friendly streets and a pleasant road environment together with residents.”
