The installation of Contech’s Slotted Drain™ system provided an efficient and effective way to capture surface runoff.
In the heart of Manhattan, Kansas, KDOT solved its U.S. 24 traffic challenge at the K-13 and K-113 intersections by adding two roundabouts. To further enhance the safety, Slotted Drain™ was installed as an innovative solution to efficiently handle the anticipated sheet flow in the area, curbing accidents and bolstering driver safety.
A deteriorating, multi-span timber bridge on West Ridge Road in West Donegal Township, Pennsylvania was replaced with a precast CON/SPAN® B-Series Bridge System on EXPRESS® Foundations. The new single-span structure spanning Conoy Creek provided a durable, low maintenance and cost-effective solution.
The turf conversion project at Aloha High School in Aloha, Oregon introduced new impervious surfaces, necessitating stormwater treatment. Two StormFilters met water quality requirements by capturing particulates and adsorbing pollutants from runoff.
When designing a Culvert or Storm Sewer the designer needs to take into consideration the type of end treatments that are available in the marketplace. The Federal Highway Administration (FHWA-HIF-12-026 Hydraulic Design Series Number 5) recommends that all pipe 48” in diameter and greater needs to have proper end protection. This selection is one of the major decisions as the Engineer of Record that you must make. Both prefabricated and constructed in place installations are available options for the designer.
Infiltration systems can be an effective way to manage stormwater, reduce runoff, and support groundwater recharge. But like any stormwater BMP, they need to be protected if they are expected to perform over the long term. That is where pretreatment comes in. Pretreatment removes trash, sediment, debris, and other pollutants before runoff enters an infiltration system. This can help extend the life of the system, simplify maintenance, reduce long-term liability, and support local stormwater compliance requirements.
This session walks through key design considerations recommended by ASTM, AASHTO, ASCE, and industry associations – covering hydraulics, structural capacity, service life, and joint integrity – while exploring practical strategies to reduce material and installation costs and stretch limited infrastructure budgets.
