Water Resources

Water is essential for societies to flourish, and our firm was founded to help communities provide safe drinking water, maintain sanitary treatment systems and control dangerous flood waters. We continue to apply comprehensive, environmentally responsible best practices to a wide range of projects that can maximize water quantity and quality while minimizing cost and energy use. Our innovations have helped clients address their challenges through pioneering reservoirs, treatment processes, spillway designs, water filtration methods, erosion control techniques and reuse/alternative supplies.

Integrated Water Resource Planning

Water management requires a comprehensive approach to maximize current supplies, provide resiliency against natural disasters and uncertainty, balance flood and drought cycles, and plan for future needs. Freese and Nichols’ multidisciplinary teams use integrated planning to help communities meet water challenges with customized solutions. We apply more than a century of experience to building resilience through economically, environmentally and socially viable programs.

Innovative Water Supplies/Reuse

With increasing demand for clean water, traditional sources have given way to a broader focus on innovative water management strategies that consider reuse, desalination, groundwater storage and other options. Drawing upon the expertise of our water, wastewater and stormwater teams, Freese and Nichols helps communities provide a secure water supply through customized, innovative solutions. We assist with planning, design, water rights, environmental permits and state financing.

  • Indirect Potable Reuse (IPR):  Led numerous planning studies and designs to deliver safe and effective augmentation of drinking water supplies using Indirect Potable Reuse.
  • Direct Potable Reuse (DPR): Designed, permitted and started up the first DPR facility in North America.
  • Water Reuse Planning: Assisted with dozens of evaluations and implementations of water reuse as a supplemental source.
  • Upgrades: Extended operation of the second DPR project in North America through addition of ultraviolet (UV) disinfection.
  • Seawater Desalination: Served as owner representative for the first municipal seawater desalination plant in Texas.
  • Brackish Groundwater Desalination: Evaluated and piloted nanofiltration membranes as an energy-efficient alternative to reverse osmosis membranes for brackish groundwater desalination.
  • Aquifer Storage and Recovery (ASR): Led a drinking water well prototype, including design, permitting support, construction, water quality evaluation, infrastructure configuration and testing.
