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 resource planning empowers community leaders and water managers with a greater understanding and practical solutions for their water supply challenges today and in the future. For utilities, a strong customized water planning strategy will convert resource challenges to opportunities, support system adaptability and resiliency, and mitigate uncertainties. For communities, it will enhance quality of life, protect natural resources, and create a long-term legacy of resource management.

In 1894, Freese and Nichols founder John Hawley became one of Texas’ first water consulting engineers. Since then, our firm has provided actionable answers to clients’ water, wastewater, and stormwater management issues using integrated water resource planning techniques.
