Eagle Circle Force Main Replacement

The Eagle Circle force main replacement project was completed ahead of schedule, experienced little delays, and imparted no unintended damage to the existing site. The use of multiple pipe installation methods reduced the cost of the project, created less potential for existing utility line damage, and provided several benefits for the project.

The force main replacement project included preliminary design, final design, permitting, construction inspection, and construction administration services for 8,275 lf of 12-inch HDPE force main consisting of 259 lf of jack-and-bore within a 24-inch steel casing, 5,671 lf of pipe bursting, 1,331 lf of horizontal directional drilling (HDD) and 1,014 lf of open cut to replace aging C-200 PVC and cast iron pipe. The project included right-of-way (ROW), maintenance of traffic (MOT), and Florida Department of Environmental Protection (FDEP) permitting.

The execution method used during the Eagle Circle project created many benefits for everyone involved, including the SSNOCWTA and the general public. Advantages included cost savings, reduced construction schedule time, and minimized damage to third-party utilities and the environment.

The Eagle Circle project incorporated an advantageous bypass route that reduced the amount of jack-and-bore locations and bypass piping required. The tie-in location under the roadway was completed using an existing gate valve rather than carrying out a wet tap, which avoided additional road damage. During pipe bursting, several repair clamps were encountered. Proper planning and coordination among the FDEP, Seminole County ROW, Seminole County MOT, the Seminole County Sheriff’s Department, Seminole County Crossing Guard, The City of Casselberry, and Sterling Park Elementary ensured a smooth project. Incorporating trenchless technologies such as pipe bursting, sliplining, jack-and-bore, and HDD reduced roadway damage, golf course disruption, and involvement of nearby residents. The additive value of all the advantages incorporated into the project saved the SSNOCWTA more than $215,000 and one to two months of construction time. Using existing infrastructure, applying multiple pipeline installation techniques, and keeping a constant line of communication between all stakeholders saved the SSNOCWTA costs and reduced completion time.
