DSRSD is rehabilitating a major sewer pipeline that runs under Village Parkway in Dublin all the way to the wastewater treatment plant in Pleasanton. Work in Dublin is from mid-June through August and in Pleasanton from August through October.
In residential areas, the contractor will work in the daytime to minimize nighttime noise. In commercial areas, the contractor will work a 24/7 schedule to finish the project as quickly as possible. Work that blocks driveways and major intersections will be done at night to minimize traffic congestion.
Plastic Odor from Village Parkway Construction
Residents and businesses in central Dublin may notice a plastic smell in the air on Tuesday (August 8) and Thursday (August 10) afternoons. The odor comes from the styrene resin in the pipe liner that DSRSD is installing in the sewer main under Village Parkway.
The odor can be detected at low concentrations but is not hazardous. Studies done to date concluded that this type of resin does not appear to be a significant source of styrene or any other volatile organic compounds that are typically of concern in occupational or air quality studies.
Since any wind will spread the odor, we advise keeping windows closed. The work will last four to five hours each afternoon. For more information about the project, visit www.dsrsd.com/trunksewer
Installed in 1960, the Dublin trunk sewer is nearing the end of its useful life. DSRSD did acoustic and video studies in 2014 to assess the pipe's condition and then hired an engineering firm to design a cost-effective rehabilitation project that would minimize impacts on businesses and residents.
DSRSD proactively manages vital community infrastructure to maintain essential services, avoid costly emergency repairs, and protect public health and the environment. The expected cost of the project is $6.7 million. DSRSD invests a portion of sewer charges over time to pay for projects like these.
Sulfides in wastewater have caused significant corrosion (dark yellow patches) to the interior of the Dublin trunk sewer, exposing reinforcing steel in some locations. DSRSD is rehabilitating the 57-year-old pipe in the summer of 2017.
