Columbia, MD — Stormwater spill way relines with Snap-Tite

Stormwater Management Pond Pipe Relined with the Snap-Tite Culvert Lining System

Problem
Stormwater management (SWM) ponds are common in Maryland and there is a push to improve them to meet current standards. These ponds were part of a design in all stormwater projects 20 to 40 years ago, so any development of any size that has a pond must be maintained. Updating the ponds to current standards is part of that maintenance; and often, the main spillway outlet pipe is part of the design to meet current regulations. A stormwater management pond in Columbia, Maryland needed an upgrade to meet the Maryland Department of Environmental Protection (DEP) regulations. The main spillway pipe made of corrugated metal pipe had deteriorated and needed to be repaired or replaced. The large SWM pond is located in a very large and busy business park. Plus, the spillway pipe was deeply buried under a highly trafficked roadway. If traffic was disrupted due to construction it would interrupt the businesses and customers using the business park. Therefore, a method of repair such as digging and replacing the pipe was not an option. In addition, a dig and replace method would require digging a dam embankment, which could be costly.
