We have extensive experience evaluating the hydrology and water quality impacts and developing mitigation plans for urbanized and less developed areas from a watershed-level down to the smallest site. We have successfully provided services from planning and modeling through design, construction, and maintenance phases.

Watearth’s staff have completed hundreds of hydrology and hydraulics studies, FEMA submittals, and flood control, storm drainage, and water quality designs. Projects range from regional SF Bay Area GI, City of LA Sidewalk EIR with hydrology modeling for the entire City of LA, and City of Houston Regional Stormwater Master Plan covering all watersheds in the city, Statewide Natural Channel Design project Texas Water Development Board, and Winding Meadow and Willow Creek watershed studies. Watearth has also conducted site-specific design and expert witness for flood control failures and water quality and erosion issues. FEMA submittals experience includes flood plain fill, structures, converting Zone As to studied streams, and experience in restudying watersheds on behalf of FEMA.

Watearth’s Water Resources expertise ranges from large regional conservation efforts for major clients to extensive Water Supply Assessments (WSAs). We provide full-service design and modeling for projects involving water distribution systems, water quality, groundwater, conservation, and contaminants. We audit and peer review existing design and have authored many master plans. Watearth possesses expert Geographic Information System (GIS) capabilities and employs this tool to ensure accuracy of our work.

We provide comprehensive demands analyses for wastewater/greywater systems including planning, modeling, design, and sizing for greywater. We incorporate cutting-edge hydraulic analysis to determine peak flows based on comprehensive assessments of future needs, providing recommendations for public agency and private institution clients on cost-efficient solutions. We perform collection system design, flow projections, master planning, modeling, and nutrient mass balance studies.
