To accommodate the City of Frisco’s rapidly growing downtown and business district with an expanded sanitary sewer interceptor, Garver delivered a design with longevity, reduced maintenance costs, and the capacity for future expansion. Considering the depth of the Stewart Creek North Interceptor — up to 40 feet underground — and the corrosive environment, Garver specified fiberglass pipe and polymer concrete manholes. Those choices helped create a corrosive-resistant system to extend the life expectancy of the four-mile pipeline, limit the need for future rehabilitation, and accommodate existing and future flows for a city that has grown by more than 150,000 residents over the last two decades.
More than anything, the city needed an interceptor that was more or less maintenance free, considering the city’s growth in the area and future plans along the route.Paul Banschbach Water Project Manager
