Water Reuse Strategy Evaluation

Have Questions? Let's Discuss​ Water Reuse Strategy Evaluation

Reduce Operational Costs for Trucking and Disposal by Reusing Frac Fluids for Two Unconventional Gas Asset Areas

The Challenge

Integrated Sustainability’s client was looking to reduce their operational costs for trucking and disposal of frac flowback and produced water by reusing as much as possible during future completions. These costs are expected to increase as the client ramps up production. The client has requested that Integrated Sustainability complete a Water Reuse Strategy Evaluation that will recommend a water treatment process and site selection for associated infrastructure including treatment processes, storage and pipelines/roadways. The aim of the water reuse strategy is to provide a reliable water source that meets slickwater frac water chemistry requirements.

The Result

A multi-criteria analysis was conducted to compare and contrast two options against the base case with respect to the technical, environmental, regulatory, economic (capital and operational costs), and social benefits. An option was identified as the better water reuse strategy for the client for the following key reasons:

  • Elimination of fresh water consumption during regular operation
  • Reduction of brine disposal volumes by >40%
  • Provides an overall average OPEX savings

Mine Water Treatment Plant – Northern B.C.

Major constituent removal was focused on selenium and metals and was designed to treat water to environmental discharge criteria. The selenium treatment system can perform up to 6,500 m3/day. The metals remove system can perform up to 16,000 m3/day. Integrated Sustainability provided discipline engineering including plant layout optimization and piping design to maximize performance while reducing footprint and cost.

Water Intake Engineering, Procurement, and Construction Management

Integrated Sustainability was retained by the client to design a revised river intake that reduces the volume of sediment that is introduced into the raw water supply system. The revised system is to provide increased reliability and easier maintenance. The new design would need to be completed and submitted to receive regulatory approval within a condensed timeline.
