The commissioning of the new Central Pumping Station and Wastewater Plant in Tupelo, Mississippi, in November 2025 capped a multi-year effort to upgrade and renovate the city's wastewater infrastructure. PENETRON ADMIX SB, a crystalline waterproofing admixture, and PENETRON ADMIX RP, an identical admixture with added red pigment for precast applications, were specified over competitive products to waterproof and protect the new concrete structures from the corrosion and chemical attack of constant exposure to effluent.

ORLANDO, Fla., Nov. 4, 2025 /PRNewswire-PRWeb/ -- The commissioning of the new Central Pumping Station and Wastewater Plant in Tupelo, Mississippi, in November 2025 capped a multi-year effort to upgrade and renovate the city's wastewater infrastructure. PENETRON ADMIX SB, a crystalline waterproofing admixture, and PENETRON ADMIX RP, an identical admixture with added red pigment for precast applications, were specified over competitive products to waterproof and protect the new concrete structures from the corrosion and chemical attack of constant exposure to effluent.

The 7th largest city in Mississippi with a population of 38,000, Tupelo is a commercial, industrial, and cultural hub for northern Mississippi and continues to grow thanks to robust growth in the healthcare, retail, and financial services industries. The city is widely known as the birthplace of Elvis Presley and is also home to the popular Natchez Trace Parkway as well as a unique buffalo park.

In an ongoing program to upgrade the town's wastewater infrastructure, Tupelo officials recently completed a multi-million-dollar project to renovate and upgrade the city's central pumping station and the wastewater treatment plant. The station had not seen any major upgrades since its initial launch in 1980.

"This project is the centerpiece of the state funds to upgrade the drainage, water, and sewer treatment capacity in Tupelo," adds Richard Farmer, Eastern Region Sales Manager for Penetron USA. "The new central pumping station feeds 75% of the city's gray water flow to the wastewater treatment plant for treatment."

The project consisted of renovating and upgrading the central pumping station, including gravity sewer line additions, lagoon modifications, new wet well structure, pumps, sewer outfall, and control equipment.

Specified by Cook Coogins, the project engineers, PENETRON ADMIX SB was chosen over a competitive product to waterproof the wastewater treatment plant's new concrete structures, including the concrete floor and walls of the new central pump station. PENETRON ADMIX RP, the identical crystalline waterproofing admixture as PENETRON ADMIX SB, with a red pigment added as a quality guarantee to meet requirements in the precast market, was used for the precast manhole elements in Tupelo as a superior alternative to interior sealer applications.

Once added to the concrete mix, Penetron's admixtures reduce concrete permeability by permanently self-sealing microcracks, pores and capillaries. This protects against water penetration and effects of corrosion deterioration, even in the aggressive environment of a wastewater treatment plant.

"Added during the batching phase, both admixtures also provide projects with a self-healing capability to reseal cracks that develop during the lifetime of the concrete," adds Richard Farmer. "Senter Transit Mix, a division of B&B Concrete, as a long-time Penetron client, prefers the advantages of an integral concrete waterproofing solution like PENETRON ADMIX."

The Penetron Group is a leading manufacturer of specialty construction products for concrete waterproofing, concrete repairs and floor preparation systems.
