Water and Wastewater Engineering

Water and Wastewater Planning

Freese and Nichols has one of the largest groups of professionals dedicated to water and wastewater system modeling and master planning. We’ve completed a wide range of master plans, regulatory assistance services, and asset management implementations. As a result, we can provide a big-picture view of your systems to prioritize your solutions, maximize existing infrastructure, and optimize your budget. Our solutions enable you to implement long-term solutions while being good stewards of financial resources.

Transmission and Utilities

As a leader in water and wastewater systems, Freese and Nichols is the firm of choice for fast-track and complex projects. In recent years, we’ve designed more than 1,400 miles of pipelines in urban, suburban and rural environments, and pump stations with a combined capacity of over 9 billion gallons per day. Our designs account for initial capital cost, total life cycle cost, low operations, and maintenance (O&M) cost, reliability, and resiliency. We customize our designs to meet your specific needs and follow through with construction management, startup, and O&M services.

Water and Wastewater Treatment

Freese and Nichols provides services in Water Purification and Resource Recovery – also known as Water/Wastewater Treatment – for municipal, state and federal clients across the southeast United States. We regularly serve as program manager or design consultant for water and wastewater treatment projects resulting in multi-billions of gallons per day in total treatment capacity for our clients. We lead planning studies and plant designs, as well as provide construction phase and startup/commissioning services for advanced water, wastewater and water reuse treatment systems.

Our practice is built on a legacy dating to 1894, when treatment was one of the original services offered by our firm’s founder, Maj. John Hawley. Today, our nationally recognized experts offer broad experience in process innovation and design for water and wastewater treatment, with a commitment to quality and client service.
