Carlyle Road stormwater pump station (SWPS) is one of four SWPS’s in Mosgiel that pump excess flow to Silver Stream when the capacity of the gravity system is exceeded in storm events. The pump station operation is critical to the performance of the stormwater network in storm events.
This project is to ensure the existing stormwater network continues to be able to operate effectively.
What we need
There are three pumps in Carlyle Road pump station and they are configured to operate based on the volume of stormwater that arrives at the pump station. One of the three pumps was installed in 1961 while the other two pumps have been in operation since 1974. These pumps are at the end of their serviceable life of typically 25 years and are due for replacement.
Due to the risk of failure of any of these pumps and their criticality to the storm water network, it was decided to replace the pumps to ensure network integrity prior to a new SWPS being designed and constructed at Carlyle Road following the Reid Avenue SWPS upgrade project.
The intent of this procurement is to modify the existing pump station building, well, pipework and electrical switching to suit the replacement pumps that have been purchased separate to this project.
