Environmental and Water Resources

OHM’s Environmental and Water Resource Group is a specialized team of engineers with technical expertise in the areas of water supply and distribution, sanitary sewer collection, storm water management, wetlands and watershed issues. This group of talented experts is practiced in the latest engineering techniques, software usage and modeling.
What we do:

• Storm water management studies
• Hydraulic/hydrologic analyses
• Water distribution studies, and pump station, storage tank and treatment design
• Vulnerability assessments
• NPDES Phase II consulting – Voluntary Permit assistance
• Storm water BMP design
• Funding mechanisms for water, sanitary and storm system improvements, along with capital planning and rate studies
• SSES studies
• Inflow and infiltration studies
• Wetland identification, preservation and mitigation
• Well house and well field development and design

Innovative Tools
As if being technical experts in environmental and water resources weren’t enough, OHM engineers and technicians just love to create new and better tools to advance communities. Here are just a few of the latest creations:

i3D
Antecedent Moisture (AM) model is a new methodology used to perform hydrologic modeling. i3D is a continuous model that closely matches observed flow data over time. It’s unprecedented accuracy serves means that communities are better able to predict how rain events will affect the sanitary sewer system and size the system appropriately, usually at tremendous savings to taxpayers.

iTrack Sewer
iTrack Sewer is a simple concept that merges database, Graphic Information Systems and modeling applications into an easy-to-use web-based tool for communities to demonstrate sewer system capacity.

WIN
(Water Infrastructure Number) is water main assessment prioritization matrix. It tracks field conditions and theoretical (hydraulic) conditions, combined with capital priorities and risk components to plan a community’s infrastructure improvement program.
