Wastewater Treatment & Collection Structure Projects 

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.

This project involved the construction of a new lift station to replace existing wastewater settling ponds in compliance with updated EPA regulations. The new lift station serves as a fully enclosed holding tank designed to manage wastewater efficiently while ensuring long-term durability and environmental compliance.

The new lift pump station at Poste de pompage Pintendre Lévis 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 high levels of H2S that cause microbial-induced corrosion (MIC).

The T.E. Maxson Facility, which began operations in 1975, plays a crucial role in Memphis's wastewater treatment infrastructure. The facility treats an average of 70 million gallons of wastewater per day and has the capacity to handle peak flows of up to 120 million gallons during storm events. It serves over 230,000 residents of Memphis, part of the city's population of more than 650,000.

The City of Reedsburg is undertaking a comprehensive upgrade to its wastewater treatment plant, which is located within a floodway and has been facing significant operational challenges. The plant has experienced recurring flooding, particularly in 2008 and 2018, which has compromised its functionality. Additionally, the plant, initially designed in 1969, has reached its capacity and can no longer meet the growing demands of the city's wastewater treatment needs. As a result, the city has initiated a multi-phase project to construct a new, more resilient wastewater treatment facility, build a new central lift station, and demolish the outdated infrastructure. This project, designated as Project A, has been allocated a budget of approximately $109 million.

The City of Fargo's sewer extension project involved the installation of 1 wet well, 6 units of 6-foot diameter manholes, and over 14 components of sewer lines and lift stations. Bio-San was specified for the project to protect the concrete from MIC (Microbial-Induced Corrosion), harmful chemicals, and water penetration.

The Niwot Sanitation District (NSD) in Colorado USA, undertook a significant project to modernize its wastewater treatment plant (WWTP), driven by the need to meet new environmental standards and replace outdated infrastructure.
