Comprehensive Wastewater Treatment Construction Expertise

With a proven track record in delivering high-performance wastewater treatment infrastructure, our team specializes in building robust, sustainable, and regulatory-compliant systems for municipal and industrial clients. From pretreatment to final discharge, we construct every component with precision and efficiency to ensure seamless integration, optimized performance, and long-term operational success.

Our Expertise: From Pretreatment to Post-Treatment

1. Headworks & Pretreatment

Effective wastewater treatment begins at the headworks, where we construct systems designed to remove large debris and protect downstream processes. Our expertise includes:

• • Bar Screens & Fine Screens – Removing solids and debris to prevent clogging.
  • Grit Removal Systems – Designing and installing aerated grit chambers and vortex systems to capture sand, silt, and gravel.
  • Pump Stations & Lift Stations – Constructing high-capacity pumping solutions to maintain consistent flow throughout the plant.

2. Primary Treatment

We build infrastructure that facilitates efficient sedimentation and separation of solids to enhance downstream biological treatment, including:

• • Primary Clarifiers – Designing and constructing high-performance clarifiers for sedimentation and solids removal.
  • Equalization (EQ) Basins – Regulating hydraulic and organic loading fluctuations to protect treatment processes.

3. Secondary & Biological Treatment

Our expertise in biological treatment ensures optimal nutrient removal, energy efficiency, and effluent quality. We construct:

• • Aeration Basins – Implementing advanced aeration systems for biological oxygen demand (BOD) reduction.
  • Bioreactors – Building Moving Bed Biofilm Reactors (MBBRs) and Integrated Fixed-Film Activated Sludge (IFAS) systems for enhanced biological treatment.
  • Membrane Bioreactor (MBR) Systems – Constructing high-efficiency membrane bioreactors for advanced filtration and water reuse applications.
  • Secondary Clarifiers – Installing clarifiers that separate biomass from treated effluent to maintain plant efficiency.

4. Sludge Handling & Energy Recovery

Proper sludge management is critical for sustainable wastewater treatment. We build:

• • Digesters – Constructing anaerobic and aerobic digesters to stabilize sludge, recover biogas, and reduce waste volumes.
  • Flare Systems – Installing biogas flare systems for safe combustion and emissions control.

5. Disinfection & Post-Treatment

To ensure compliance with water quality regulations, we specialize in constructing post-treatment systems, including:

• • Chemical Feed Systems – Building precise dosing systems for coagulation, flocculation, and nutrient removal.
  • Chlorine Contact Basins – Constructing optimized basins for effective pathogen disinfection.
  • UV Treatment Systems – Installing ultraviolet disinfection systems for chemical-free pathogen removal.
  • Dechlorination Systems – Implementing sulfur dioxide and sodium bisulfite systems for residual chlorine neutralization.

6. Effluent Storage & Discharge

The final stage of wastewater treatment involves safe effluent storage, reuse, or discharge. We provide:

• • Water Storage Tanks – Constructing bolted, welded, and pre-stressed concrete tanks for treated water storage.
  • Effluent Discharge Systems – Designing and installing outfall structures that meet environmental discharge standards.

A Commitment to Excellence

Our team is dedicated to constructing wastewater infrastructure that is durable, cost-effective, and environmentally responsible. We leverage cutting-edge construction techniques, advanced project management methodologies, and a deep understanding of regulatory requirements to deliver projects on time, within budget, and to specification.
