This is a Sanitary Sewer and Lateral Replacement Project. We upgraded the Existing Sewer System by Installing 20 New Manholes and 8,285 LF of New Main and Lateral Connections to 133 Units. We Successfully Created Various Phases for this Project and Managed Traffic Control to Limit the Impact on the Residents During their Daily Activities. We Encountered Various Obstacles such as Unknown Existing Utility Locations and Massive Rock. We were Able to Resolve these Issues by Utilizing our Means and Methods that Allowed Us to Overcome the Unknown Conditions in an Economical Manner.
