Building high-resolution decision-support tools for planners and designers in drylands.

Sectors: Built Environment, Water & Wastewater


We analyze cities to create localized water supply solutions that work.

Divining Lab’s geospatial tool, Hazel, integrates surface and sub-surface data to provide planners and designers with scenario-based feedback on stormwater capture options in drylands.

Hazel integrates water supply with water quality considerations, and correlates performance data including embodied energy, carbon emissions, and economic cost/benefit to evaluate the impact of design decisions on aquifer recharge, and the impact of stormwater management on project costs. Planners, designers, and property owners use Hazel to assess complex data rapidly.

Our models:
• Streamline access to complex data from disparate sources;
• Operate at hyper-local and regional scales;
• Couple surface and subsurface data at high-resolution;
• Compute costs/benefit of design scenarios.

Proof Points

Our models enable users to:
• Accelerate water-smart planning and design;
• Test multiple design scenarios;
• Prioritize investment in green infrastructure;
• Evaluate impacts on water, energy, and carbon conservation objectives; • Facilitate decision-making across jurisdictions;
• Optimize water supply and water quality.
