Project Name: Proposed 250mm Ø Sewer Line along Taft Ave. cor. Quirino Ave. Manila
Date: October-December 2009.
Client: Maynilad
The project was to install a 250mm Ø PVC Sewer Line just beside the LRT Quirino Station, on the northbound lane of Taft Avenue. The size of the steel casing is 500mm Ø, and the depth of the work was about 4.5m below the surface. The project was difficult because it was grade-sensitive. The procedure done was to first use a pilot drill, and then attached to it was the 500mm Ø steel casing so it would follow the line and grade done by the initial drill. The hole that was supposed to drill should have an inclination in such a way that the water would flow from one side to another; it was challenging, but the sewer line was installed successfully in the end. This contract was done October to December 2009.
