PROJECT DESCRIPTION:

Abergeldie was engaged to design and construct upgrades and extensions to the wastewater reticulation network at St Marys to increase capacity to serve anticipated industrial and residential growth in the district. The works were undertaken in the Penrith valley of Western Sydney and a stretch across three local government areas: Penrith City Council, Blacktown Council and Fairfield City Council.

Works comprised of design, construction testing and commissioning of:

  • New sewage pumping station, SPS1184
  • emergency storage for the pump station to meet NSW EPA sewage systemlicence requirements
  • Construction of 4.2 km of pressure main pipeline comprising of trenchless, mircrotunnelling (including 300m beneath the M4 motorway) and open trench construction.

PROJECT DESCRIPTION:

Abergeldie was contracted to Greenway Living to construct a new Sewage Pumping Station (SP1181), Sewage Pressure main and associated civil infrastructure works in 3 Separable Portions.

The sewage pumping station Works involve construction of a 5.3m diameter, 8.7m deep in-ground reinforced concrete wet well with inlet maintenance hole, emergency relief structure, valve chamber, bypass bund area, concrete hardstand and vehicle access area. Electrical and comms conduits, pits and switchboard. The project scope also involves roadwork’s including truck turning bay, kerb and gutter, footpaths, stone retaining wall, storm water drainage and rising main works.

The new Sewage Pumping Station SP1181 will serve 799 Richmond Road and the adjoining lots.

PROJECT DESCRIPTION:

The works, carried out under the Sydney Water Network Facility and Renewals Program (NFRP) involved upgrading 21 existing chemical dosing systems across seven Sydney Water plants. The packages included condition assessment, design, epoxy lining, new unloading bays, new dosing lines and replacing existing pumps and pipework inside the bunds. Most of the sites needed to remain operational during the upgrade, so temporary dosing systems were established so the work could be done.

PROJECT DESCRIPTION:

Abergeldie were engaged by Unity Water to install new sewer main and construct a Sewer pumping station. The scope of works included installation of pumps, pipe work and ancillary equipment, relocation of services, emergency storage construction, cabling, pump station construction, testing and commissioning.

PROJECT DESCRIPTION:

Major upgrade to an existing sewage treatment plant to increase capacity and improve process performance standards to meet the needs of increasing residential populations in South Eastern Queensland’s regional centres. Works addressed all areas of the plant’s mechanical and chemical processes, systems and supporting infrastructure, with particular attention to upgrading of PLC/SCADA based controls.

Complex Challenges:

All works were carried out under brownfield conditions immediately adjacent to a continuously operating existing plant. Cutting-in of new process elements and pipe work had to be closely coordinated with the plant’s operations management team. Some work could only be carried out under “permit to interrupt” conditions.

Excavation for the extensive network of new connecting pipelines had to be undertaken with great care and accuracy due to the large number of existing underground service lines.

Civil construction work was programmed around the procurement schedule, as some major items of equipment had a delivery lead time of up to 24 weeks.

Project Description:

Abergeldie was contracted by Thiess Pty Ltd to carry out the complete mechanical fit out and the above ground pipe installation for the Goodna STP upgrade 4A. The end user is Queensland Urban Utilities.

The upgrade involved the building and commissioning of the following areas:

  • Oxidation ditch
  • Primary treatment Area
  • Membrane bio-reactor
  • Blower room
  • Secondary anoxic area
  • Permeate slab
  • Chemical storage area
  • Methanol storage tank and accessories
  • The service water system
  • The wash water system
  • The foul liquor pump station

Abergeldie was also involved in the design, supply, install and commissioning of the instrument air system, reclaimed effluent, potable water, citric acid dosing, alum dosing and caustic dosing systems.

Project Description:

Secondary Treatment Facility Augmentation
Upgrade of secondary treatment facilities including three clarifiers, RAS pumping stations, anoxic tanks, level control structure, MCC building, pipelines, methanol dosing facility, MLR pumping stations, bioreactor modifications, access roads and associated works.

Complex Challenges:

A precast aqueduct was redesigned as an in-situ structure as it was not possible to mobilise the required crane due to the location of existing services. Special environmental control measures were required to protect the habitat of an endangered fauna species in the vicinity of the site.

Project Description:

Abergeldie upgraded Dora Creek WWTW, the capacity of the pre-existing plant was doubled by construction of new inlet works, septage receiver facility, soil bed filter; switch room, two clarifiers and pump stations. Modifications were also made to two bioreactors. Associated works included mechanical and electrical works, pipework, pumps, control systems, testing and commissioning. Civil works included new access roads, landscaping and demolition of existing inlet structures.

Complex Challenges:

The upgrade required conversion of a semi batch decant process, still in use, to a continuous activated sludge process with no license breaches. This involved modifying existing tanks, requiring detailed planning and design to ensure sections of the plant could be bypassed for long durations to allow refit and commissioning of the new sections before bringing them on line. Close cooperation between Abergeldie’s in-house design team, commissioning teams and the utility owner developed a detailed and effective system of temporary bypasses and maintained continued operation of the plant.
