Rehabilitation of a 100 year old brick sewer was designed for the City of Los Angeles (The City). The project was challenging not only because of the poor internal condition of the sewer but also due to the fact that it is non-circular in shape. The rehabilitation is designed to be executed in three phases. The first phase was completed in the year 2000 and involved rehabilitation of 2.5 miles of the sewer. Phase II involved rehabilitation of about 2.7 miles of pipeline, the design for which was completed in May 2008 and is expected to begin construction in summer of 2009. The design of the last phase to rehabilitate about 4.5 miles of the sewer is currently underway with scheduled completion by end of September 2009.
