Wastewater & Pipeline

The Gildea Group has a history of quality service, cost-competitive pricing, and schedule execution in municipal construction, midstream pipeline utilities, and design-build services since 1982.

The pipeline arm of The Gildea Group was founded in 1982 by Mark Gildea as Pipeline Systems to provide construction services to the oil and gas industry in the Appalachian Basin. At that time, the primary focus was on building gas gathering systems and setting up tanks, units, and wellheads for the booming Medina gas play in northwestern Pennsylvania. 

In the late 1980s, the company diversified into municipal water and wastewater projects. At first, the projects mostly consisted of water distribution and sewage collection pipeline projects before shifting their focus to water and wastewater treatment plant projects. Our team has now completed dozens of water and wastewater treatment facilities in western Pennsylvania.

The Gildea Group has completed projects of all different pipe diameters with distances ranging from a few thousand feet to over ten miles. The company has also completed several facility projects ranging from compressor stations to water intake facilities.

The Gildea Group is widely known for taking on more challenging projects and operating safely, timely, and efficiently.

Eastvale Water Intake Structure

This was a municipal water intake structure for the city of Beaver Falls, PA, and the surrounding areas. The project involved building a circular cofferdam in the Beaver River and constructing the intake structure in the dam. Once the intake structure was built, the dam was removed. The structure consists of large concrete chambers with intake screens to allow water into the pumps. We installed equipment to remove debris and pre-treat the raw water before it is pumped to the main treatment facility.


This project was a brand-new regional wastewater treatment plant for Saxonburg, PA. The project consisted of an oxidation ditch, raw sewage screw pumps, a circumfuse for sludge dewatering, glass-lined sludge storage tanks, final clarification, and UV disinfection.

Sewickley Wastewater Treatment Plant

This project was the construction and renovation of the Sewickley municipal wastewater treatment plant. This project included a new mechanical bar screen, a new influent screening building, a belt filter press, grit removal equipment, multiple pumps, primary and secondary clarifiers, and digesters.

Potato Garden Finley Township Municipal Authority

This project was a brand-new municipal wastewater treatment plant for Finley Township, PA. This project included primary and secondary clarifiers, digesters, two glass-lined trickling filters, pumps and values, and a centrifuge. 

Bethel Park

This project was an upgrade to the existing water treatment plant for the South Park Municipal Authority in Pennsylvania. The project consisted of a large UV system, multiple 42” ductile iron pipes, final clarifiers, demolition of existing tanks, and complicated foundations.

Fish Creek

This project was a brand-new water intake structure for a local energy company. The project consisted of installing a 30-diameter pipe into the creek to pump the creek water into a wet well. From there the water was pumped to a rig owned by the client for fracking purposes. PSI constructed a structural steel platform around the wet well with H-piles and concrete foundations. 

Forward Compression Station

This project was a two-bay addition to an existing compressor station for a local energy company. The project consisted of constructing complex concrete structures and setting the glycol contact towers.

The Boggess

This project was the re-positioning of equipment at a dehydration station for a local energy company. The project consisted of the removal and reinstallation of dehydration station equipment from one pad to another.
