Grand Haven Township Manager Bill Cargo said an 8-inch cast iron fire line recently ruptured under the roadway, near the Actoflex Inc. facility at 14260 172nd Ave.
“Because this fire line was installed in the early 1970s, and because the break in the fire line is located within the public right of way under 172nd Avenue, and because there is no agreement regarding the maintenance responsibility for the fire line, the township will assume the costs for the repair and replacement of this 8-inch line,” Cargo said.
Since cast iron becomes brittle with age, the entire fire line from the water main to the property line will need to be replaced, Cargo noted.
The township no longer uses cast iron for any water mains. It now uses cement-lined ductile iron pipe.
Township staff say they hope a temporary fix can be used to contain the break. The road was saw-cut Tuesday in preparation for today’s repair.
“The temporary repair will be replaced with a permanent, new fire line this spring,” Cargo said. “And the road will be repaired.”
Cargo also noted that, because it isn’t known how much sand may have been displaced by the water main break, they are unsure how much of the roadway will need to be replaced this spring.
Township officials said the road should be reopened by the end of the day today (Wednesday).
