REPAIR OF WATER MAIN CROSSING IN BRIDGER CREEK
CITY OF BOZEMAN, MONTANA
SEPTEMBER 1995
PROJECT NEED:
A leak has developed in an 18-inch cast iron (C.I.) water main that crosses Bridger Creek. The
repair of the 18-inch water main is along the southern bank of Bridger Creek.
PROJECT DESCRIPTION/SEQUENCE and MITIGATION MEASURES:
The City intends to repair the 18-inch C.I. pipe in the following manner:
1. Sandbags will be placed from the south bank of Bridger Creek (creek) to encircle the
pipe section which is to be repaired.
2. Water will then be pumped from the enclosed sandbagged area into a sediment removal
area consisting of firmly staked hay bales to filtrate pumped water prior to re-entering
the creek.
3. The water within the enclosed sandbagged area will be pumped to an acceptable level to
perform the work and the leak repaired. All in-stream work shall be completed in an
expeditious manner to avoid unnecessary impacts to the stream, a two day construction
duration is anticipated. All construction activities performed in the strewn and immediate
vicinity, shall be conducted in a manner to reduce in-stream turbidity along with
minimizing disturbances to the streamaed and-or streambank. Extra precautions shall be
taken to preserve existing vegetation. All streambank and adjacent areas disturbed by the
construction activity shall be protected with temporary erosion control measures during
the construction activities.
4. After completion of the work, those areas disturbed by the construction activity shall be
reclaimed with long-term erosion control measures and revegetated immediately after
construction.
