Yering Gorge pump station transfers water to Sugarloaf Reservoir from the Maroondah Aqueduct and the Yarra River. The facility has been in operation for approximately 40 years as part of the larger Winneke Water Treatment Plant.

Through the design and construct team Aqua Metro Services, we completed the design for the replacement of the two service water strainer sand the by-pass pressure regulating valve assembly under a design and construct project. The former Gordon Marr & Sons strainers were removed and replaced with Amiad ABF-10k series units. The by-pass regulating valve assembly was redesigned to address historical problems with blockages due to organic material from the two available raw water supplier.

Pakenham Main SPS and Inlet Works Upgrade

CMP completed concept, functional and detailed design of the Pakenham Main SPS and Inlet Works upgrade to take the capacity from approximately 130 L/s to 415 L/s using the existing site.

This required a significant amount of detailed hydraulic analysis to determine the optimum screen velocities and determine how the capacity of the existing system could be significantly increased without the need to duplicate building footprints.

Eastern Treatment Plant – Power Station Ventilation Upgrade

Eastern Treatment Plant – Power Station Ventilation Upgrade

Through the design and construct team Aqua Metro Services, we completed the design and installation of an evaporative cooling system for Melbourne Water’s Eastern Treatment Plant power station. The evaporative system was to augment existing ventilation as well as provide cooling capacity.

Over 30% of ETP’s power requirements are generated from the cogeneration power station. The heat load within the power station building is excessive for operations and maintenance personnel, with temperatures regularly in excess of 50 oC.

The existing system consisted of filtered ventilation fans only, with no cooling capacity. External air was distributed through three levels of the power station building by fans located in the in the building’s basement. Previous remedial ventilation works had not been successful at reducing the engine room temperatures to satisfactory levels.

The installation of a supplementary evaporative cooling system was identified as the preferred solution in MWs options assessment.

As part of detailed design, a 3D CAD model was developed from existing drawings and a drone photo survey. The model was used to improve tie in of the new equipment into existing spaces and was critical during the safety in design and constructability reviews. It enabled improved consideration of maintenance access and potential equipment and construction clashes.

Western Treatment Plant – Cocoroc Precinct Access & Security Upgrade

Melbourne Water made the decision to relocate the Western Treatment Plant administration office complex on New Farm Road in Werribee away from rapidly encroaching residential developments in order to locate operators and service providers closer to the plant. The new office complex at the WTP Cocoroc Precinct provides accommodation for WTP operations and maintenance staff and for community education programs. The new administration and maintenance shed buildings were occupied in August 2019.

The purpose of this project was upgrade access roads and security at the WTP Cocoroc Precinct to comply with MWC’s security and safety standards.

Key project design features included the following:

  • Upgrade of the section of Metropolitan Farm Road from Cocoroc Road to 40S Road;
  • Upgrade and surfacing of Cocoroc Road from Farm Road down to the proposed education precinct at the intersection with 25W Road, making provision for buses accessing the education centre;
  • Provision of a public and bus access road and turning circle for the administration building;
  • Upgrade and surfacing of Boundary Road from Farm Road to the entrance of the chlorine plant;
  • Provision of an emergency gravel access road from 25W Road to William Thwaites Drive;
  • Installation of a twin leaf electrical sliding gate and lighting on Farm Road north of 40S Road, with provision for number plate recognition, CCTV and fob access;
  • Provision of a crushed rock carpark for 100 staff vehicles for the new administration building including installation of wheel stops, bollards, lighting and CCTV camera poles;
  • Provision of a masterplan and installation of storm water drainage for the precinct including the connection to the new administration building;
  • Provision of regulatory and wayfinding signage and linemarking;
  • Upgrade of sections of farm and security type fencing along William Thwaites Drive, Farm Road, Cocoroc Road and 25W Road; and
  • Installation of concrete and crushed rock paving around the new administration building.

Sugarloaf Reservoir Pump Station – Service Water Upgrade

Sugarloaf Reservoir Pump Station – Service Water Upgrade

Through the design and construct team Aqua Metro Services, we undertook the upgrade of the Sugarloaf Reservoir Pump Station (RPS) service water system. The RPS service water system supports the three 1.6MW main pumps which maintains throughput to the Winneke Water Treatment Plant. The project scope entailed optioneering replacement equipment with Melbourne Water stakeholders and incorporated modern design technology to minimise clashes with existing services, as well as allow for construction to be undertaken with the facility available at short notice.

Key  project highlights include the following:

  • 3D terrestrial scan to capture existing infrastructure and equipment.
  • 3D model of the upgraded facility, accounting for clashes with retained equipment and services.
  • Virtual Reality Walkthrough with Melbourne Water stakeholders.
  • In total the following assets were replaced under the project scope:
  • 2x vertical multistage pumps (Potable Service Water).
  • 2x vertical multistage pumps (Raw Water Service Water).
  • 2x Main Raw Water Strainers (Amiad SAF4500, 300µm).
  • 1x Emergency Raw Water Strainer (Amiad saf3000, 40 µm).
  • 3x Main Pump Flow Control Assemblies (Gland Seal, Bearing Cooling and Motor Cooling)
  • 150m+ Service Water Process Pipework for Gland Seal, Bearing Cooling and Motor Cooling Processes (Potable and Raw Water)

Challenges with construction resulted in a staged approach being performed, with MWC stakeholders heavily involved in the outage planning with AMS Design and Construction team members.

Pakenham Sewage Treatment Plant Upgrade

Pakenham Sewage Treatment Plant Upgrade

Pakenham Sewage Treatment Plant Upgrade

The Pakenham STP upgrade for South East Water included the following works:

  • Options study on screening type and performance including contacting every water authority in Victoria to discuss performance and on-site experience with screening issues and “lessons learnt”.
  • Design, construction, modelling and reporting of physical modelling using a 1:10 scale model to optimise screen design and operation including baffle/flume design and flow splitting.
  • Detailed design of an inlet works upgrade including a 100 L/s relift pump station, 350 L/s Raw Sewage Pump Station, and concept design of maceration at the pump station inlet;
  • A 260 L/s capacity effluent reuse pumping station;
  • Upgrades and modifications to the existing bioreactor; and,
  • New bioreactor tanks including aeration, anoxic and swing zones.

Due to mixing complexities and the particularly aggressive/difficult nature of the incoming sewage, specialised investigation and testing was undertaken including:

  • Computational fluid dynamic modelling (3D CFD) of the anoxic/swing zones to optimise mixer sizing, location and tank baffling arrangements.
  • In-situ diffuser testing trialling a variety of diffuser materials over a 6 month period. The testing included progressive back pressure trending, cleaning effectiveness and material degradation tests.
  • Physical modelling of the inlet works including band screens, step screens and the associated channels/pits.
  • 2D effluent modelling of various clarifier energy dissipater inlet arrangements to optimise clarifier performance.

The additional design effort put in “up front” worked well, as South East Water was able to ensure project requirements were well documented and the system was easy and straight forward to initially commission.

Cost Savings: All significant upgrade components were analysed in detail over a range of options to determine the most appropriate option.  The tank height and depth were optimised for capital and operational expenditure.  The cost savings to South East Water were in excess of $1.5M.
