It’s not every day you get the opportunity to excavate and suspend a nearly 100-year-old, 72-inch water main. On Louisville Water Company’s Crescent Hill Water Treatment Plant Secondary Pump Station project, MAC is constructing the new Junction Structure that will connect the new pump station to the existing plant infrastructure.

The 72-inch influent pipeline linking the old and new systems, segment one installed via tunneling, has now been completed. Next up is the final influent pipe section: a 30-foot-deep open-cut excavation, including approximately 20 feet of solid rock, to tie the systems together and bring this critical infrastructure improvement one step closer to completion.

Complex work, careful planning, and exceptional ex*****on by the entire project team.

Trench safety week is coming to an end, but trench safety never stops. Trench safety is built on everyday actions—planning the work, inspecting conditions, and looking out for one another. Through consistent and ongoing safety training to build safe behaviors, we create safer jobsites and stronger teams and projects. Trench and Excavation safety is a decision you make every day.

Trench safety starts with great habits. Taking the time to ensure protective systems are in place and hazards are communicated to protect everyone on the job. Safe choices made every day build a stronger team and ensure everyone goes home safely. Trench and Excavation safety is a decision you make.

Trench Safety Week reminds us that every trench can be dangerous, but every incident is preventable. Taking the time to inspect excavations, use protective systems, identify hazards, and follow safe work practices protects lives. No deadline is worth risking a worker's safety. Plan the work, protect the trench, and make sure everyone goes home safely every day. Trench safety is a decision you make.

Since 1980, MAC Construction has grown from a start-up excavation company into one of the most trusted names in civil construction by continually evolving to meet the needs of its customers and community.

That commitment to building stronger communities extends far beyond construction projects. Through the support of MAC Construction & Excavating and the Louisville MSD Community Benefits Program, VIPS received a $29,100 investment to support our Early Childhood Intervention Program.

This funding helps provide qualified, vision-specific teachers to children and families throughout Jefferson County, bringing support directly into the home. By partnering alongside parents, VIPS helps children who are blind or have low vision build the foundational skills and confidence needed to reach their highest potential.

Thank you, MAC Construction & Excavating, for your incredible generosity, and thank you, MSD Community Benefits, for making this possible.

This milestone is a testament to the employees, families, owners and partners who have been part of the journey along the way. We’re proud of our past and excited for what’s ahead as the 45th Anniversary celebration continues.
