Project Details


BACKGROUND


Mt Crosby East Bank WTP is one of the largest sources of water for the South East Queensland Water Grid with 1,000 ML/d of installed pump capacity. Mount Crosby East Bank Raw Water Pump Station (RWPS) draws water from the Brisbane River through two intake tunnels, the pump station consists of eight dry wells, approximately 25 – 30 m deep with each well containing a pair of pumps.  The pumps are connected by line shaft to motors located approximately at ground level (varying by well).


The pump station is located on the bank of the Brisbane River and has been adversely effected by multiple flood events over the last 100 years. Minor flood events result in the flooding of the wells, including line shaft bearings and instrumentation being inundated, with larger flood events inundating the HV motors as well. The pump station has been adversely effected by flood events six times since 1890.


Given the criticality of the pump station, Seqwater’s target is for the RWPS to be able to withstand a flood event without substantial damage and be able to be put back into operation in a short period of time. 


OBJECTIVE


The objective of this project is to develop a solution for the replacement of the Mt Crosby East Bank RWPS HV motors and / or pumps to achieve the required level of flood resilience. As such, market capability is being investigated and information is being sought on suitable submersible pumps and motors.

The base proposal to meet this objective includes the following:

  • Twelve x 50 ML/d (600L/s @ 110m) submersible pumps to be dry mounted at the bottom of Wells A to F capable of operating submerged.
  • Four x 1.8 MW, IP68 submersible motors to be mounted on the existing motor floor level of Wells G & H.


Other outcomes that achieve flood resilience will also be favourably considered, including the options for:

  • 100 ML/d (1,200 L/s @110m) Submersible pumps suitable for installation at the bottom of Wells G & H.
  • 900 kW, IP68 submersible motors mounted on the existing motor floor level of Wells A to F.


PROCESS


KBR has been engaged by Seqwater to develop a preferred solution for the replacement of the HV pump motors and / or pumps at Mt Crosby East Bank RWPS. As part of this project, a market enquiry is being undertaken to demonstrate probity that a wide segment of the market has been consulted, and to review the market capability. This process will involve a public notification process with the intent of encompassing the broad market for this equipment. This is a non-binding process intended to capture details of equipment solutions of motors and submersible pumps serving the need of the project including electrical motors, and/or electrical motors and pump arrangements.


The Supplier is encouraged to read the document against the work-package below to find further details on the requirement. The Supplier shall populate the Returnable Schedule by completing an EOI on ICN Gateway, identifying which items can be supplied (or identifying alternate solutions).  The EOI process will mandate the interested suppliers to download the template and upload the completed information. 


As this is a retrofit application, not all of the existing motorspecific requirements may be able to be met, it this is the case, deviations should be advised by the Supplier.
