Water and Sewer Relocations

Under three open-end contracts from 1991 through 1998, we had 35 assignments for the relocation of water and sewer lines, ranging from 200 feet to four miles long.

Water main relocations varied in size from 8" to 60" and have included a 16-inch main in a 48-inch diameter tunnel under the Amtrak Railroad.

Sanitary sewer design included gravity sewers from 8" to 33" and a grinder pump pressure system.

Of particular note is the relocation of a 60" water main along the west side of the Capital Beltway, necessitated by the construction of a new interchange at Arena Drive in conjunction with the Redskins Stadium. This project was performed on a "fast track" basis, and we worked closely with several other consultants and the State Highway Administration. The project won the Maryland With Pride Award of Excellence in 1998.
