Water and sewage projects are outsourced to private companies in the Manila metropolitan area. It has been a long time since the water and sewer pipes were laid, and the laid pipes have deteriorated over time. A water and sewer pipe replacement project is planned.Initially the project was designed by Open cut method.However, due to the traffic situation in Manila in recent years, the construction has been changed to a Trencheless method because it may cause further traffic congestion when construction is performed. It is possible to minimize the negative impact on traffic, which is a feature of Trenchless work. In the future water supply and sewerage business, Trench less construction will be the main construction method.
