PROJECT N0. 1 – FEMA PA FUNDING APPLICATION
WEST TARKIO RIVER PIPE CROSSING - GRANT TOWNSHIP SECTION 25

  On March 22, 2019 a 10” water main break was located 4.5 miles east of Shenandoah on Highway 2 at the West Tarkio River pipeline crossing. The 10” line break caused a significant loss of public water service after it drained the 300,000 Gallon water tower located 2 miles west. 
  Severe flooding and erosion at the pipe crossing site
caused the line to shift and break near the west water
edge. An attempt was made to repair the line but unstable river bank conditions and shifted pipe alignment made the repair impossible.

To restore temporary water service to 480 residences and towns in Fremont and Page counties a 2” line was hung above the river by using 3/8” cable and clamps. 

J.W. Excavation was hired to dig along the west river bank to attempt to repair the 10” water main on March 23, 2019.
 The 10” line river crossing will be replaced by directional boring 600 feet of restraint joint pipe 15 feet deep under the river channel. 
 Morris & Co. will complete the bore work by April 30th. The bore work bid and tie-in costs is $65,000.00. SWRWD has purchased the 10”pipe at a cost of $12,282.00

A 2” restraint joint pipe was attached above the river
channel and connected to the 10” water line located in
the farm fields. Gate valves were installed on the 10” line to isolate the pipeline river crossing.

10” pipe failed near west edge of river channel

MARCH 2019 – WATER SYSTEM FLOOD DAMAGE

WORK SITE N0. 1 – Emergency temporary water service supply
March 22, 2019. Flood damage to West Tarkio River resulted in
river- bank erosion and soil bearing load shifting breaking the 10” 
pipeline crossing under the river. The 10” line could not be repaired 
due to the pipe joint misalignment and work conditions. A 2” water
 line was hung above the river to provide limited water service to 440
rural residents and the towns of Imogene and Westboro. The 300,000
Gallon water which is supplied by this 10” line was drained during the
line break and only 5 feet of water could be maintained until the 10” line
river crossing was replaced.

 On April 16, 2019 Morris Co. was hired to bore and pull 600 feet of 10”
yelomine restraint joint pipe under the river. The bore was completed on
April 17, 2019 for a bid cost of $65,000.00

West Tarkio River – Grant Township Section 25 - State Highway 2
WORK SITE N0. 2 – Replace 6” water main creek crossing due to flood damage erosion. Morris Co. bored and pulled 420 feet of 6” yelomine restraint joint pipe on April 19, 2019 for a bid cost of $24,800.00
Final tie-in work not completed as of June 11, 2019.


There is a substantial amount of erosion around the county culvert. The Page County engineer’s office was contacted and met at this site. They concluded that stabilizing the creek banks and the Highway road bank was not a priority at this time.
