Lady Bird Lake Water Quality Modeling, City of Austin, Texas

Plummer was contracted by the City of Austin to develop water supply strategies that could be implemented during severe drought. This option involved enhanced wastewater treatment and conveyance of reclaimed water to Lady Bird Lake. Plummer developed the watershed model of an urban and rural area of more than 150 square miles, ran sensitivity analyses, performed model calibration, assessed existing and potential temporary wastewater discharges into the lake to define water quality impacts and potential treatment and permitting strategies. Plummer will support the public input process to help define the recommended water supply strategy.
