Gulf Run Sanitary Sewer Replacement and Rehabilitation

Status

In Design

The County is working with its consultant to fully complete the project’s design phase and submit the final design before sending it out to bid (time frame TBD)

Location

The project limits are Gulf Run Pump Station by the intersection of 36th Road North and Military Road, along Military Road to the north, to 38th Street North and North Oakland Street. View map

About the Project

This project is part of the Sanitary Sewer System Improvements program (Water Sewer Maintenance Capital), which are included in the Utilities portion of the FY 2025-2034 CIP. Sufficient funds are available in the Utility Construction Fund to provide for construction of this project. Please see descriptions and the photo gallery on this page for details on the proposed work.

Sanitary Sewer

The sanitary sewer collection system is a key piece of infrastructure consisting of approximately 465 miles of sewer pipes and 13 lift stations. This intricate network exists to make sure that the wastewater that gets flushed every day from homes and businesses makes its way to the Water Pollution Control Plant (WPCP) where it’s properly cleaned and treated before being recycled back into the environment. Learn more about our sanitary sewer system.

Project Description

The project will rehabilitate and replace approximately 2,500 linear feet of sanitary sewer pipe, including the upsizing of approximately 2,200 linear feet of the existing 10-inch cast-iron force main (pressurized pipe) located uphill from the Gulf Run Pump Station, as well as the upsizing approximately 250 linear feet of gravity sewer pipe. The existing force main and gravity sewer pipes are in need of rehabilitation and replacement as they are approximately 60 years old and deteriorating, and the force main has experienced many breaks. Furthermore, upsizing the pipes allows for increased sewage capacity to continue services and meet future needs.

More specifically, this work includes the open-cut installation of approximately 1,000 linear feet of 12-inch force main pipe on Military Road, 38th Street North, and North Oakland Street, as well as the open-cut installation of approximately 250 linear feet of 18-inch PVC gravity sewer on North Oakland Street. Finally, the project will include the sliplining of approximately 1,200 linear feet of 14-inch force main pipe along Military Road between the Gulf Run Pump Station (by 36th Road North) and 38th Street North. Please see the photo gallery, which includes an image depicting these areas of work.

Construction Process

Traffic flow will be maintained throughout the project duration. The contractor will limit noise-generating work to the hours of 9 a.m. to 4 p.m. No weekend work is anticipated. Other tasks may be addressed during the hours immediately before and after that window. A temporary bypass will be installed in order to allow for the replacement of existing pipe without disruption of service.

Sliplining Process

Sliplining is a trenchless rehabilitation process used to repair existing pipelines where a new pipe is pulled through an existing pipe. Military Road has unused water pipes that the new sewer force main pipes will be pulled through to reduce construction impacts. The new pipe, however, cannot be pulled through any directional changes in the existing water main, meaning that excavation will take place wherever there is a horizontal or vertical bend in the pipe. These areas of excavation are referred to as “access pits,” and an example of an excavated pit is shown in the photo below.

Project Timeline

This project is planned to be advertised for bid this Summer 2025. Construction is expected to begin early 2026, with substantial completion expected in late 2026 and final completion expected in early 2027.

Upon contract award and before the start of construction, a detailed letter about the project and construction schedule will be sent to the president of the Civic Association and then be distributed to residents who will be directly impacted by the project.
