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.
A partial list of our treatment service offerings is provided below.
