Greeley considering boring for new pipeline from Bellevue to Greeley

From the North Forty News (Cherry Solkoloski):

The city is planning to bore underground, rather than excavating a ditch, through sensitive areas just south of the Cache la Poudre River. Spokesperson Dan Moore said preliminary plans call for a series of bores, for a total of about a quarter mile of pipeline. The so-called northern segment through LaPorte is just one of several sections of pipeline that will take water from the city’s Bellvue treatment plant all the way to Greeley. Some of the segments have already been completed, but the northern segment’s preferred route has drawn intense criticism from some landowners who will be affected. However, Moore said, the boring method “should avoid most of the concerns we have heard.”[…]

Moore said that with the boring method, the city should be able to avoid destroying the historic features and the Point of Rocks. The city would bore under the irrigation canals and through a ridge just south of the Point of Rocks. It would go under the old railroad bed at some point, but the intact tracks would not be disturbed. Moore said the approach would be friendlier to the environment. The access road could be smaller, and the area would be easier to restore. The process would likely involve digging three boreholes, about 20 feet deep, from which the tunnels would be bored. There are always surprises when doing underground work, Moore cautioned, and the city might have to excavate in some areas if they encounter large chunks of rock…

Moore said that the cost difference between boring and trenching is difficult to assess. Although boring is a more expensive construction method, restoration of the property would cost less with that approach. Even with boring, he said, Greeley is sure that the preferred route on the south side of the river would be less expensive than the other alternatives considered…

Construction could begin next winter on the project, Moore said, and the project could take two seasons to complete. The city avoids doing pipeline work in the spring and early summer because of farming activity, irrigation and wildlife. Before work can begin, the city must acquire necessary permits from Larimer County and the U.S. Army Corps of Engineers. The Army Corps will consult with the Colorado Historical Society before issuing a permit.
