Boat Harbor Treatment Plant Pump Station Conversion in Newport News, Virginia
Market: Marine
Service: Support of Excavation Design
The Boat Harbor Treatment Plant Pump Station Conversion in Newport News, Virginia, is an important part of the Sustainable Water Initiative for Tomorrow (SWIFT) program. This project involves constructing a main pump station complex with a 55 million gallons per day (MGD) intermediate pumping system, a grit removal system, a 2.0 MG inline storage tank, and a 36.5 MGD transmission pumping station. Additionally, a 12.0 MG offline storage tank is being built adjacent to the main complex. These developments aim to enhance wastewater management by diverting flow to the Nansemond Treatment Plant in Suffolk, where advanced treatment processes will produce SWIFT Water™ meeting drinking water standards, thereby reducing nutrient discharge into the James River Basin and supporting Chesapeake Bay restoration efforts.
D.W. Kozera, Inc. (DWK) played a critical role in this project by designing the support of excavation for a 40-foot-deep excavation near the I-664 bridge, a task complicated by a high water table and the need to terminate the sheet pile wall 5 feet above the bridge’s batter piles. DWK’s engineering solution helped the project to stay on-track and the excavation reached its target depth in May 2024, marking a significant milestone in the project’s timeline.
