110+ Years of Successful Water and Wastewater Treatment Partnership

GFT helps public and private clients across the country meet the growing need for reliable, clean water.

Water Treatment
GFT’s award-winning work encompasses planning, study, design, and construction-phase services for water treatment plants nationwide. We also modernize, rehabilitate, and expand existing facilities to meet clients’ evolving capacity and treatment needs.
GFT has led the way in utilizing technologies such as ozone, granular activated carbon, dissolved air flotation, and absorption clarification. We have implemented conventional treatment, abbreviated clarification processes, high-rate granular media filtration, or advanced membrane filtration for surface waters based on the raw water quality challenges presented. GFT has conducted bench-scale, pilot plant-scale, and full-plant scale treatability studies to evaluate various treatment processes, to determine design criteria for new facilities, and to evaluate modifications to existing processes. In short, we’ll work together to find the best solution for you.
