The project includes sewer pipe reconstruction (approximately 2,600 LF), sewer pipe lining (approximately 9,800 LF), manhole reconstruction (15 manholes), manhole rehabilitation (approximately 330 LF), and manhole invert repairs (33 manholes). The preliminary plans for the project can be viewed below: Project Plans (PDF)
