Drainage Construction and Coridoor Development is Lahan Municipality's Municipal Pride Project. This endeavor aims to establish an advanced underground sewer network to efficiently and safely collect and dispose of sewage. Concurrently, an elevated green corridor will be developed above the subterranean sewer infrastructure. This innovative approach not only addresses essential sewage management needs but also enhances the quality of urban life. The envisaged green corridor will serve as a multifunctional space, fostering recreational and leisure activities for the residents of the area. This dual-purpose project represents a holistic and sustainable urban development strategy, seamlessly integrating environmental stewardship with community well-being.
