Wastewater Treatment & Collection Structure Projects 

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.

The Municipalité de Saint-Maurice undertook the expansion of its potable water reservoir system, constructing two new reservoir units for water treatment and distribution. A key design requirement for this project was to avoid the use of traditional membranes, which are prone to degradation, detachment, and long-term maintenance issues in water containment structures.

Initially built in 1889, the 8th Avenue Reservoir is the largest and oldest of the city's 37 reservoirs, supplying clean drinking water. Bowen Engineering chose Xypex Admix C-500 NF for its proven, durable, long-lasting waterproofing performance as part of a comprehensive rehabilitation project, including tank-in-a-tank construction, vault improvements, and overall reservoir upgrades.

The City of Grand Junction, in partnership with Mesa County, has initiated Phase 1 of the Persigo Wastewater Treatment Plant expansion—an important step in enhancing water quality, safety, and environmental sustainability. This upgrade introduces new screening processes, advanced electrical systems, expanded biosolids storage, and improved aeration and disinfection systems, modernizing the facility to meet growing community needs.

The City of Terrebonne, Quebec, undertook a critical infrastructure modernization initiative, constructing a new water treatment plant to enhance water quality. The new water treatment plant required a long-term solution against harsh sewage conditions with high levels of H₂S. Xypex Bio-San is a uniquely designed admixture for integral, long-term concrete protection in harsh sewage conditions with levels of H₂S that cause microbial-induced corrosion (MIC).

Built in 1967, the original wastewater treatment plant faced mounting challenges due to aging infrastructure and increasingly stringent federal discharge regulations. Significant upgrades were necessary to meet new environmental standards and ensure compliance with updated permits, requiring enhanced treatment processes to safeguard local waterways.

This project involved the application of Xypex crystalline waterproofing across 60,000 sq ft of concrete manure holding tanks in Clovis, New Mexico, for Vanguard Ag, a developer specializing in agricultural waste-to-energy systems. The tanks support anaerobic digestion, a process that breaks down farm and food waste to produce renewable biogas and agricultural byproducts.
