Largo WWRF Influent Pumping Station and Head Works

Project Overview

Preparedness is your best bet to winning a race against Mother Nature. The city of Largo in Florida, often in the path of hurricanes, needed to upgrade its wastewater reclamation facility with the capacity to handle intense and prolonged rain events at the flip of a switch.

The Largo Influent Pump Station includes a new head-works facility to process flows and prevent clogs, and an odor-control system. The new-and-improved station has the increased capacity to handle up to 43 million gallons of wastewater per day, providing it with the ability to overcome heavy downpours and remain fully functional. PCL upgraded the facility, which included a five-million-gallon equalization tank capable of holding surge flows. The new infrastructure was incorporated into the City’s supervisory control and data acquisition system, which allows the City to control the flow of water in and out of its facility from a safe, off-site location.

PCL installed two 30-inch-wide raw-sewage pipes by jacking and boring directly underneath the facility, a narrow and congested area. While preparing the site, PCL identified several critical power feeds that ran through the intended excavation. To avoid undermining the facility’s underground utilities and potentially harming the plant’s primary power source, the project team created a 3-D model of the facility’s current underground power and pipelines. Together with the owner, PCL decided to relocate the lines to a less congested area of the plant. This eliminated the risk to plant operations and provided the facility with the means to access the lines for future maintenance.
