Water / Wastewater Engineering

Our team develops new and innovative solutions to control the provision of safe water, the disposal of wastewater, and the mitigation of flood risk. As part of our Water Resource Management services, we work to identify additional sources, improve utilization of existing withdrawals, enable water reuse, and promote demand management.


Water & wastewater master planning is a key element needed to develop water, wastewater, and reclaimed water infrastructure. We develop calibrated GIS-based models as tools to address plant capacity issues, level of service, fire flow requirements, and assess risk.

Consistent with our “One Water” philosophy, we relentlessly focus on ways to integrate utility needs with the overall environment.
