Wastewater Engineering:
Sewerline Replacements and Rehabilitation

WEI has designed many capital improvement sewer line replacements and rehabilitation. Projects have included replacement in old streets very congested with utilities, very soft subgrades, emergency replacement design for a 24" interceptor along a washed out river bank, and trenchless technology such as pipe bursting and cured-in-place liners. Sewerline smoking and use of dye in services for tracking has also been used on several projects. Jobs have also included manhole rehabilitation.

Selected Projects

South Avenue Reconstruction, Grand
Junction, CO
Roadway contained 24", 21", and 15"
parallel combined sewers. Designed for
combined sewer separation using existing
lines and some new sanitary sewerline.
Smoked lines and flushed dye down toilets
to determine all active services from what
sources going to which lines. Special
challenges were other utilities in the same
street - two active waterlines, a medium
pressure 10" gas line, 12" high pressure gas
line, two banks of underground electric,
overhead high voltage lines, irrigation
pipeline, underground telephone, and a
new 48" storm drain, all in 80' of R.O.W.

1997 Sewerline Replacement, Grand
Junction, CO
Designed replacement of 2,538 feet of
sewerline in several locations in city
streets, dealing with public, traffic, and
utility issues.

1996 Sewerline Rehabilitation, Grand
Junction, CO
Design rehabilitation of 3672 feet of 15" to
30" sewerline and manholes in city streets
and across private properties in easements,
dealing with public, traffic, and utility
issues
.


Peach Street Reconstruction: Phase II,
Fruita, CO

As part of designing road reconstruction,
designed 2182' of sewer in very soft
subgrade and replaced 35 services.
Replacement parallel sewer had to cross
old town intersections with substantial
utility conflicts, plus provide improved
service designs for several businesses. Also
provided construction oversight.

Poudre River Interceptor Sewer, Fort
Collins, CO
Designed 3,000 feet of 24" emergency
replacement sanitary sewer line because the
river bank had washed out. Design
included two (2) river crossings.

1998 Sewerline Replacement, Grand
Junction, CO
Designed replacement of 6,292 feet of
sewerline in seven locations in city streets,
dealing with public, traffic, and utility
issues.

1996 Sewerline Replacement, Grand
Junction, CO

Design replacement of 6,833 feet of
sewerline and 111 services in city streets,
dealing with public, traffic, and utility
issues.
