texas general spiral rib pipe

Texas General – 2014 DOT Project of the Year

By: Contech Engineered Solutions

As a part of an ongoing effort to replace aging and inadequate storm drainage systems, the City of Pharr and the Texas General Land Office needed to upgrade a smaller, reinforced concrete pipe (RCP) drainage system that included a main trunk line of large box culverts which intercepted approximately 320 acres of surface runoff in a densely populated area.

Not only would the needed concrete boxes be difficult to install in such tight site constraints, the manufacturing costs and logistics required were expensive and exceeded project budget.

The City decided to pursue alternative solutions, and after careful deliberation selected Contech Engineered Solutions‘ polymeric spiral rib – a corrugated steel pipe (CSP) solution that is one of the most hydraulically efficient storm sewer systems available.
