Case Study Details

Montrose County Public Works recently completed a box culvert and wingwall drainage improvement project at the intersection of carnation road and 6000 road in Olathe, Colorado. The work included installing JET Filter’s closed-end stainless steel weep hole systems to improve drainage performance and protect the integrity of new reinforced concrete barriers. Box culverts and concrete wingwalls are particularly suceptible to hydrostatic pressure, water pooling, and soil migration if proper drainage is not provided. At this rural Colorado site, seasonal runoff and saturated soils posed a serious long-term risk to the structural performance of the new concrete infrastructure.

Products Used

• 16 units of JET Filter – JF4SSCVLV: 4″ Diameter Closed End Maintainable Weep Hole Filter with Check Valve, featuring ASTM 316/316L Stainless Steel Housing and Mirafi® Filter-Weave FW 300 Geotextile Filter Media.

Solutions

Montrose County engineers sought a reliable solution that could prevent pressure buildup and extend the life of the culvert system with minimal maintenance. Working with Buckhorn Engineering and Core & Main, the county installed 16 JET Filter closed-end maintainable weep hole assemblies into the concrete wingwalls and barriers of the culvert system. This will allow for controlled water discharge, while filtering out sediment and minimizing long-term erosion – ensuring durability for years to come.
