TRA CRWS Master Plan

Dallas, TX


Detailed Master Plan leads to 39 capital improvement projects

Garver performed the most-detailed evaluation of the Trinity River Authority (TRA) Central Regional Wastewater System (CRWS), which manages 405 million gallons per day (MGD) of flow. The Garver team evaluated plant capabilities, capacities, and treatment paradigms; projected future flows and loadings; anticipated regulatory requirements; and completed processes and hydraulic modeling assessments while delivering a new plant process model and hydraulic model. The final 20-year Master Plan was the result of a 22-month effort that developed 39 capital improvement projects. Each project evaluation included life cycle cost analysis, uncertainty analysis using Monte Carlos simulations, and non-economic evaluations.
