Curved Microtunnel Project
Saves Time, Effort
Jeff Griffin | Senior Editor
BRH Garver recently completed two
segments of major sanitary sewer system
improvements in Houston, employing
microtunneling. The bores consisted of
4,600 linear feet and 4,200 linear feet of
60-inch-diameter gravity sewer tunnel
at depths to 70 feet. Hazen and Sawyer
designed both projects for the owner,
the city of Houston.

BRH-Garver served as the primary
contractor on the downstream segment,
Package 1A, of the Chelford City Diversion
program, while installing the
upstream segment, Package 1, for prime
contractor, Boyer Inc.
In addition to microtunnel installation
of 60-inch centrifugally cast, fiberglass-reinforced,
polymer mortar pipe
(CCFRPMP), the downstream project
included trenchless installation of 48inch
CCFPRMP for future connections
and polymer manholes. Pipe was supplied
by Hobas Pipe USA.
BRH-Garver also constructed a large
cast-in-place structure for the downstream
connection of the entire Chelford
City program on an existing 108
