Abstract

This Milwaukee Metropolitan Sewerage District project will require 3200 feet (975m) of 30 inch (750mm) diameter reinforced concrete microtunnel pipe to be installed at depths up to 64 feet (19m).

This specific design of microtunneling pipe was submitted to the owners by the low-bid installer and was accepted as an equal alternate to the original specifications. Microtunneling is a fairly new installation process, the technology of which allows for the trenchless installation of buried conduit while minimizing the need to disturb the street surfaces and/or private properties.

The project is scheduled to start June, 1998 and has an August, 1999 completion date.
