Tennant Avenue Sewer Main Project

The City's current Sewer Master Plan identifies the existing 18-inch sewer pipe within Tennant Avenue between Monterey Road and Railroad Avenue as deficient under peak flow conditions and recommends that it be increased in size to prevent sewer overflows within this segment of the City's sewer system. The project is included in the adopted FY18-19 through FY 2023-24 Capital Improvement Program. 

The scope of work includes removal of the existing sewer pipe and installation of new 27-inch sewer pipe, auger bore under the Union Pacific Railroad tracks, temporary sewer bypass system, new manholes and/or manhole modifications, manhole coating, lateral reconnections, traffic control, project clean up and video for quality control.

The City of Morgan Hill has contracted with K.J. Woods Construction, Inc. to install a new sanitary sewer main on Tennant Avenue between Monterey Road and Railroad Avenue. No interruption of sanitary sewer service is expected. This critical infrastructure project is needed to ensure the City’s Sewer System is proactively maintained and that an aging sewer line is replaced and upgraded before failure. This proactive work helps to ensure system reliability and supports public safety and protection of the environment.  


Night Work is scheduled for Thursday, December 12, 2019 beginning at 8pm. Work includes video taping the new sewer pipe for quality control and some minor manhole modifications. Traffic control will be in place with only one lane of travel available. 

Work installing the 27 inch sewer pipe will continue during the day. Only one lane of westbound traffic will be possible during this work. This work is expected to take a month or so to complete. The next phase of work consists of boring/jacking under the railroad tracks. This work will impact both directions on Tennant Avenue, thus only one lane of traffic will be available in both directions. This work could start as early as December 20th.

Additional traffic impacts will occur along Tennant Avenue for the next six months. We will post these impacts as soon as the information becomes available. Traffic control will be conducted between the hours of 8:00 a.m. to 4:00 p.m., Monday through Friday. During the work, traffic control devices will be set up and No Parking signs will be posted in advance. Access to residents, deliveries, and emergency services will be provided at all times during the roadwork. For your safety, please travel through the work zones/detours carefully or utilize alternative routes. Please plan for extra travel time when traveling through Tennant Avenue. The City appreciates your cooperation and apologizes for any inconveniences while construction is underway as there will be some noise, minor inconveniences, and traffic delays during the work.
