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.

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.
