More Irrigation Reservoir Work

Late last fall one of our irrigation pumps was not performing as it should.  The decision was made to repair the pump and the pump was then removed after the new year.

Soon after removing the pump it was realized that leaves being sucked into the pump was the major cause of our pump issues.  The screen at the base of the pump had deteriorated to the point it was letting leaves enter the pump turbines.  The leaves ultimately caused damage to the pump which required repair.



To eliminate the risk of future leaf issues we began investigating potential entry points of leaves into the pumphouse wet-well.  This lead us to emptying the reservoir so we could see the inlet pipe to the wet well.  To our surprise we found holes in our metal inlet pipe, which holds our self cleaning strainer.  The holes were on the bottom portion of the pipe and is probably why we didn't see them last fall when we worked on the strainer.


The short term fix was to use a "tar-like" paste and metal mesh to cover the holes.



The long term fix will most likely come in the form of Cured in Place Pipe.  We will collect quotes on this project and plan to have it done within the next 4-6 years.
