Reducing Risk With Single-Source System Implementation

Turnkey EPC Water Treatment Solutions

Need help planning and executing large capital projects? Our clients have found great value in using a single-source solution for their water treatment needs. Partner with WesTech for a full-scale implementation that prioritizes performance, schedule, and safety. With a single point of responsibility, you’ll reduce the risk of delays and cost overruns from design changes that hold-up delivery.

We begin with feasibility studies, lab testing, and front-end engineering to ensure that you get a quality system within a competitive price range and timeframe. Then, our experienced team develops a comprehensive project-execution plan that meets your most challenging water and wastewater system needs, including full design, equipment supply, installation, startup, and operations.

We have executed engineer-procure-construct (EPC) turnkey projects worldwide, in a variety of industries. We also have a long history in equipment engineering for the water and wastewater industry. By relying on this strong combination of WesTech’s in-house engineers and treatment equipment, you can rest assured that your project will go smoothly.

Working with WesTech:

  • Shortens timelines
  • Lowers capital and operating costs
  • Places an emphasis on operability and maintenance
  • Optimizes plant processes

Partnering With You for Collaborative Delivery

When you work with WesTech as your EPC, we maintain a close collaboration with you for the design of the water treatment plant. The integration of project team members takes place early and often – the design and construction teams work closely with the owner from the very beginning of planning.

This planning and communication effort creates a better-managed schedule with phasing and critical path items incorporated into construction documents. Collaborative delivery teams do not necessarily make decisions based on the lowest bid but on the most skilled, experienced, and innovative suppliers.

Collaborative delivery results in:

  • Fewer delays
  • Fewer change orders
  • A more efficient and accurate procurement process

Partner with us for strategic oversight of the entire project and a customized, cost-effective solution engineered for the site conditions of your individual project. Our offerings include:

Case Studies

With our turnkey projects, you can meet required discharge limits without having to coordinate with multiple resources for an overall process solution.

Complete FGD Installation

At a power facility in the Midwest, WesTech successfully provided all of the necessary turnkey deliverables for FGD treatment, from initial process and instrumentation diagrams, conceptual equipment layout, equipment supply, and wet commissioning to effluent discharge with contaminants below permit limits. The WesTech design-build team has helped numerous power stations like this one across the globe by providing treatment to remove sulfates and heavy metals from their waste streams. The treated water is then safely discharged into local receiving water bodies or recycled in the station.

Our design-build projects closely integrate design and construction, providing significant customer efficiencies and time savings.

Fast-Track Design-Build Wastewater Treatment Plant

After a tragic fire destroyed much of a refinery, WesTech provided a replacement wastewater treatment system that now allows the refinery effluent water to be recycled back through the system. The design, equipment fabrication, and installation were provided in an astonishing six-month period, allowing the refinery to once again begin production.
