The government will check old sewage pipes every three years. This is because some roads have sunk down. They want to find problems early. They will also build new ways for water to flow.
To prevent road collapses, the government is revising laws to inspect aging sewage pipes more frequently. Pipes with significant corrosion will be inspected at least every three years. The plan also includes creating alternate routes for sewage flow to prepare for disasters.
In response to recent road subsidence incidents, the government has approved revisions to the Sewerage Act, mandating more frequent inspections of aging sewage infrastructure. Critically corroded pipes will undergo inspections at least triennially, and redundancy in sewage conveyance will be established through the creation of alternative routes to mitigate disruptions from disasters.
