Hydraulic and Hydrologic Modeling

As urban areas expand and environmental regulations tighten, the need for precise and efficient management of your collection and distribution systems becomes paramount. Hydraulic modeling offers a sophisticated approach to simulate and analyze the behavior of water distribution and wastewater collection systems under various conditions. Our engineers help planners anticipate future demands, optimize system performance, mitigate risks associated with inflow and infiltration, forecast capacity constraints, and estimate the remaining lifespan of aging infrastructure. By leveraging advanced modeling techniques, you can develop robust strategies that ensure sustainable water management, enhance service reliability, and support long-term infrastructure resilience.

Our advanced technical expertise

helps utilities and municipalities nimbly forecast their utility needs. When our engineers weigh alternatives, we look at multiple angles: cost, water usage, ease of maintenance, constructability, and phased implementation. Through modeling improvements and vetting design solutions, we refine plans to the most efficient and viable option within budget constraints.

Regulatory Compliance Goals

change over time and greatly depend upon the resiliency of existing systems. A fundamental aspect of the water utility systems planning process is ensuring that all development activities comply with relevant regulations and standards and achieve the targeted level of protection required by state and federal environmental agencies.
