About this Event
In response to increased wastewater flows generated by the transformative Chula Vista Bayfront redevelopment, this project delivered durable and resilient wastewater infrastructure under highly constrained environmental and subsurface conditions. The site is located within a historically industrial corridor impacted by VOC- and TCE‑contaminated groundwater, high, tidally influenced groundwater, and liquefiable soils. To address these challenges while minimizing environmental disturbance, the project utilized trenchless construction methods, including horizontal directional drilling (HDD) and jack-and-bore, to install dual HDPE force mains, providing operational redundancy and reducing the risk of sewer spills. Deep soil mixing (DSM) columns and ground improvement were used for the construction of the emergency storage tank shoring, eliminating the need for extensive dewatering and groundwater treatment and resulting in significant schedule and cost savings. In addition, a floodwall and flood gates were constructed to protect critical pump station equipment from future sea level rise and flooding. Collectively, these design and construction strategies enhanced long-term resiliency, safeguarded public health, and protected San Diego Bay while supporting continued waterfront redevelopment.
