Bullitt County’s wastewater treatment system received a major upgrade recently as the West Triangle Pump Station began service, advancing Louisville MSD’s plans for greater efficiency and environmental stewardship.
The new pump station, located at 165 West Triangle Lane, is now diverting approximately 200,000 gallons of wastewater from Bullitt County per day through a large sewer pipe, called the Lower Mud Lane Interceptor, and then to MSD’s Derek Guthrie Water Quality Treatment Center, which is in southwestern Jefferson County. This new process eliminates the need for the Hunter’s Hollow Wastewater Treatment Plant, which partially collapsed in 2014, before MSD acquired the system.
Bullitt County Judge/Executive Jerry Summers called the activation of the West Triangle Pump Station “a landmark moment for our county’s infrastructure.”
“We are ensuring that Bullitt County remains a clean, sustainable place to live and do business,” Summers said. “This isn't just about moving water; it’s about moving our community forward with more reliable, modern services.”
City of Hillview Mayor Jim Eadens said the infrastructure investment will “improve service reliability and protect the local environment.”
“Activating the West Triangle Pump Station is a major step forward for our community,” Eadens said.
MSD Senior Collections System Engineer Joey Ashby said that the West Triangle Pump Station will have a positive impact on the environment by dramatically reducing sewage overflows that can occur during periods of heavy rainfall.
“MSD is doing great work for the Bullitt County community and its water quality,” Ashby said. “We will continue to monitor improvements in the neighborhood streams. We expect, with this particular project, that in the coming months and years, we’re going to see significant improvements from the data we collect from those streams.”
Since acquiring the Bullitt County Sanitation District in 2021, MSD’s long-term plan has been to eliminate problematic small facilities that have outlived their useful life and reroute wastewater flows to larger treatment centers in Jefferson County.
“We are pleased to have made a number of improvements that positively impact the health and safety of Bullitt County waterways while also moving forward on our larger projects to benefit the entire region,” said MSD Executive Director Tony Parrott.
In Bullitt County, MSD serves more than 4,700 customers. MSD also acquired the Oldham County Environmental Authority in 2020, serving more than 7,000 customers.
In Jefferson County, where MSD serves almost a quarter of a million customers, numerous system upgrades are happening, including a replacement project at Paddy’s Run Flood Pumping Station that will double its capacity.
