Replacing Iron Pipe with HDPE Plastic Pipe at Arlington Cemetery
HDPE Plastic Pipe Goes Under Ground with Fewer Trenches
Time to make water main repairs at Arlington National Cemetery, and officials chose HDPE plastic pipe. The pipe laying project replaced 44,500 feet of 60 year old 6-inch cast-iron pipe with High Density Polyethylene (HDPE) piping. First, challenge was work during daytime-open hours. The feat was to install pipe under ground while 28 formal funerals occurred on an average day. Second, challenge was avoiding graves. As the final resting place of our nation’s heroes, reducing graveside impacts were crucial. Laying “trenchless” plastic material is a most effective means of getting the job done. Third, the pipe carried water. The pipe had to resist corrosion and leakage. So, with “butt-end” seamless melting the pipe together reduced the number of usual mechanical connectors which can leak.
HDPE Pipe: Many Shapes and Sizes and Built with Some Give
The topography of Arlington was a key factor in choosing HDPE plastic piping. It can be installed with easy adaptation to the landmark’s curving layout. The cast-iron piping twisted around 70 sections of the cemetery, including the famous Arlington hillside. As a result, according to an Arlington supervisor, the replacement of the old pipework progressed without incident.
As a result, HDPE plastic pipe offers a responsible infrastructure choice. It is leak resistant, flexible, energy efficient and cost effective. Plastic provides tremendous life cycle value. Finally, trenchless technology helps protect the environment from loosening ground and erosion. This plastic pipe system can help solve economic, infrastructure, and ecological problems across America.
