We face significant water resources challenges: limited fresh water sources, droughts, flooding and more. With a One Water approach, communities benefit from multi-benefit, multi-purpose solutions that lead to more sustainable and resilient water supplies, improved water quality, more efficient utility systems, healthier ecosystems and economic vitality.

Transparents assessments and long-term solutions

To date, CDM Smith has prepared over 50 One Water plans resulting in $20 billion of publicly supported infrastructure improvements.

The Water Integration Tool (WIT)

Using a systems thinking approach, our experts created and deploy the WIT to rapidly assess future needs under uncertainty and evaluate integrated alternatives across the water, wastewater and stormwater sectors.

Meangingful stakeholder engagement

For our plans, we have facilitated hundreds of workshops for increased collaboration and consensus-building.

Powerful resiliency
assessments

Our methods make climate science actionable, quantifying risks from droughts, floods, sea level rise and extreme heat.
