Wastewater Treatment & Collection Structure Projects 

Athens Utilities completed construction of the East Primary Pump Station to support wastewater conveyance and system reliability for the City of Athens. During project evaluation, the owner identified low velocity sewer flow as a contributing factor to the generation of hydrogen sulfide posing the risk of microbial induced corrosion.

The City of Wichita is undertaking upgrades to its wastewater treatment facility to improve biological nutrient removal (BNR) capacity and expand ultraviolet disinfection infrastructure. The project includes construction of new wastewater process basins and supporting treatment structures. 

The wastewater treatment plant at Cervecería Águila in Barranquilla, Colombia, encountered significant leaks in its treatment tank shortly after commissioning. The severity of these leaks was exacerbated by the corrosive nature of the leachates and chemicals present in the brewery's wastewater, threatening the tank’s structural integrity. 

The Guadalupe-Blanco River Authority (GBRA) expanded its Stein Falls Water Reclamation Facility to increase treatment capacity, improve solids management, and modernize chemical and electrical systems.

The Town of Pendleton undertook the expansion of the Pendleton-Clemson Regional Wastewater Treatment Plant to increase treatment capacity and improve long-term system reliability for the surrounding service area. 

The JEA Buckman Bio Solids Facility required durable concrete protection for new sludge holding tanks and the overhead structural slab exposed to aggressive wastewater conditions. These structures operate under continuous exposure to hydrogen sulphide and microbial activity that can lead to microbial induced corrosion. The project demanded a long-term solution capable of protecting concrete integrity without reliance on surface applied linings or membranes that require ongoing maintenance.

The Municipality of Saint-Isidore initiated an upgrade to its wastewater treatment facility to replace aging infrastructure and comply with updated environmental standards. The modernization involved the construction of new reinforced concrete structures, including a degritter building, a concrete treatment pond, and a pumping station.

On September 1, 2024, the County of Prince Edward completed the construction of a new wastewater pump station in Picton, Ontario. This critical infrastructure project was designed to enhance the municipality's wastewater collection and treatment capabilities. Located near Lake Ontario, the project presented unique waterproofing challenges that demanded innovative solutions. 

The construction of a new potable water reservoir aimed to enhance water storage infrastructure with an emphasis on durability and reliability. A key challenge was ensuring that the reservoir’s watertightness and long-term durability would protect the potable water supply from contamination and leakage while withstanding constant water pressure and environmental stresses.

The construction of a new wastewater treatment facility in Saint-Philippe presented a significant challenge in ensuring the long-term durability and watertightness of the wet well. The structure is constantly exposed to harsh wastewater conditions, including chemical attack and continuous moisture, making long-term durability and watertightness critical for operational performance. The public estimate for this project was $36.2 million.
