There has been a lot that has happened in the past several weeks. It almost seems surreal, but just before the pandemic, on March 12, 2020 the District did get some great news. It was awarded $121,273.00 through a coal grant we submitted to address the water main break. Once again, board members Bruce Brown and Brent Burton along with McKinstry Account Executive, Tyler Bush assisted me as we presented the Colstrip Water-main Grant Proposal to the Montana Coal Board.
If you remember, on December 11, 2019 Colstrip High School had a water main
break outside of the facilities between the municipal water vault and the
building where the gymnasium and classroom structure meets on the North side of
the high school facilities. The break created a significant amount of damage as
the amount of water coming out of the identified pipe not only found its way
inside the building from on top of the ground, but also came up through the
cement floor and walls and exited into classrooms through electrical outlet
boxes. (See photos below). Due to the extenuating circumstances the school
district was forced to close school for two days until the break could be
repaired. When the water main pipe was excavated and the leak identified, there
was significant concern that the pipe was compromised enough through corrosion
and time that it could certainly break again at another place between the water
vault and the building. The damages to the school district were substantial:
the loss of two instructional days as well as over $80,000 worth of damage.
Technically speaking, the original cast iron water main pipe corroded due to high
alkalinity in the soils and electrolysis. It is anticipated that the
replacement pipe will be CPVC with cast iron fittings. Sacrificial anodes will be utilized to reduce
corrosion at the fittings. The sizing of these fittings will be
determined following the compilation of a geotechnical report identifying the
actual composition of the soils.
Approximately 100 lineal feet of pipe will be replaced from the
city’s valve box to the connection inside the footprint of the high school.
We hope to get started on the water-main replacement as soon as possible. We are anticipating the funding early next fall.
Once again, stay safe, stay healthy and until we hear different stay home!
