The Rohnert Park sewer expansion project called for open-cut construction, with the use of monolithic base inserts in the manholes.
Years of problems with inflow and infiltration in its sewer collections system inspired Rohnert Park, California, to adopt new standards when it came to designing and constructing a trunk sewer expansion.
Specifically, they rethought the way they were building up manholes. Previous projects had used standard cast-in-place processes, but now, they wanted to invest in I&I-inhibiting construction technology: monolithic base inserts.
