Elk River High School needed to update their storm water management system when building a new tennis complex. Due to elevation requirements and excavation restrictions, there was a restrictive depth limit for the new system. Project leaders specified County Materials’ Elliptical Reinforced Concrete Pipe for its ability to allow higher flow capacities at shallower depths. Concrete pipe is manufactured to optimize water flow and resist flotation throughout its extended service life of 100 years or more. County Materials supplied and delivered more than 200 LF of elliptical pipe to update the storm water management system at the high school.
