Project Overview

Sentry’s SD Service division provided a comprehensive series of wastewater treatment facility improvements at the Agropur wastewater treatment plant in Lake Norden, South Dakota. This multi-phase project included strategic process upgrades and equipment installations designed to enhance reliability, hydraulics, and operational efficiency within an active, industrial wastewater environment.
 
Work was executed to support treatment performance and facility continuity while the plant remained in operation. The improvements spanned mechanical installations, process piping, bypass systems, and structural treatment enhancements.
Scope of Work
Sentry’s SD Service team self-performed a range of improvements and system modifications, including:
 
Process Infrastructure:
  • Installation and modification of wastewater process piping systems
  • RAS booster and emergency RAS line installations
  • Underground and bypass piping to support continuous operations
Treatment System Enhancements:
  • EQ tank diffuser installations
  • Mixer and agitator installations within ponds and treatment tanks
  • Clarifier scum line installation and modifications
  • Sludge thickener and sludge handling system support
  • Digester door and internal component work
 
Facility Operations Support:
  • Bypass piping systems to maintain flow continuity during upgrades
  • Wastewater tank sealing and related structural repairs
  • Crane-assisted equipment placement within live treatment zones
Work was coordinated across multiple disciplines and executed to minimize disruptions to Agropur’s production and treatment processes.
 
Key Project Features
  • Active Facility Work: All improvements took place while the wastewater plant remained operational, requiring careful planning and sequencing.
  • Multi-phase Execution: The project was completed in stages, with improvements delivered as needs arose and opportunities for enhancements were identified.
  • Self-Performed Execution: SD Service crews provided the necessary labor and equipment, including personnel, tools, and heavy machinery support.
  • System Reliability Focus: Upgrades supported enhanced mixing, aeration, and flow control, leading to improved performance and reduced risk of unplanned downtime.
Project Impact
Agropur’s wastewater treatment infrastructure now benefits from:
  • Enhanced hydraulic efficiency across multiple treatment stages
  • Improved system redundancy and bypass capability
  • Increased reliability of mechanical and process systems
  • Upgrades that support both current operations and future maintenance planning
These improvements contribute to long-term stability and effective wastewater processing at an industrial scale.
Why Sentry Was The Right Partner
Sentry’s SD Service division delivers wastewater facility improvements while plants remain operational. We self-perform process piping, mechanical installations, and system upgrades with our own crews and equipment, coordinating work to minimize disruptions and maintain treatment continuity. Our experience in active industrial environments means reliable execution, careful sequencing, and system improvements that support long-term performance.
