Pembroke Retarding Basin Upgrade (Mooroolbark)

Current

Melbourne Water is planning to deliver upgrade works to the Pembroke Retarding Basin at Mooroolbark. The upgrade works will ensure the retarding basin continues to reduce the risk of flooding to the community.

Why are we planning on upgrading the Pembroke retarding basin?

Melbourne Water has over 200 retarding basins that we regularly assess for risks, conduct maintenance on, and upgrade as necessary. The Australian National Committee on Large Dams (ANCOLD) guidelines represents the best Australian and international engineering practice in the safe design, management and operation of dams. We use these guidelines to manage our retarding basins. The Pembroke retarding basin has recently been assessed against the ANCOLD guidelines. This assessment has shown that upgrade works are necessary to ensure the retarding basin continues to reduce flood risk and operate safely for the community.

Planning Permit

Melbourne Water has received a planning permit to complete the following works at the Pembroke Retarding Basin.

Scope of works:

  • Removal of trees that are a risk
  • Filter trench on embankment to increase strength
  • Crest capping on embankment
  • Construction of a concrete cut off wall
  • Replace spillway
  • Installation of erosion control matting

Location

All works will take place within the Pembroke Retarding Basin Reserve at Mooroolbark.

What happens next?

Works will commence in July 2019 and take approximately five months to complete (weather permitting).

What to expect during construction

We will do everything possible to minimise disruption during construction, however it is likely that nearby residents will notice:

  • large trucks and machinery working around the retarding basin
  • worker amenities set up within the construction area
  • some noise, dust and vibration from construction works
  • removal of trees and vegetation from the retarding basin embankment - trees and vegetation in other parts of the reserve will be retained 
  • construction traffic and equipment will enter and exit the site via King Street.

Timing of works

Works will commence in July 2019 and take approximately five months to complete (weather permitting). Construction hours will be Monday to Friday 7am to 6pm and Saturdays from 7am to 1pm in accordance with the EPA regulations. 

Revegetation

An extensive revegetation process will be implemented once the works are completed. Trees and shrubs will be planted within the Retarding Basin (away from the embankment).
