Case Studies

Our feature case study this month is the Brisbane City Council Telegraph Road project in Bracken Ridge, Queensland.  Georgiou Group contractors and Brisbane City Council Engineers installed 164m of  triple cell 1050mm diameter ADS N12 HDPE pipe in just 8 hours saving 3 project days.

ADS N12 HDPE pipe was selected to comply with AS/NZS 2566.1 and carry road loads with shallow cover.  Rapid installation saved thBCCe project time and money.Georgiou Group

Cubic M3 supplied 164m of triple cell 1050mm diameter N12 HDPE pipe for this project in 4.0m and 6.0m lengths.

ADS N-12 HDPE Pipe – Stormwater Drainage Upgrade – WA

ADS N-12 HDPE Pipe Stormwater Drainage Upgrade – Cambridge Street, City of Sterling WA GENERAL PROJECT INFORMATION

  • Concrete pipework along Cambridge Street as part of a significant drainage upgrade.
  • ADS N-12 HDPE pipe was selected by the contractor and approved by the council as the best product to meet the needs of the project.
  • The light weight, long lengths available (4m and 6.1m) and the use of a press-fit integrated bell and spigot fitting reduced installation time over comparable materials such as concrete, reducing installation time and lowered all associated costs including traffic management

DESIGN CONSIDERATIONS

  • Swift installation required – Cambridge Street is a major thoroughfare and any disruption to traffic would cause significant problems for road users, local residents and businesses.
  • Swift project completion required to avoid additional traffic management costs to the council and its contractors.

DESIGN STANDARDS

  • Materials used had to comply with the relevant Australian design standards and codes.
  • HDPE stormwater pipe as a minimum had to meet AS2566.1.

ADS N-12 HDPE Pipe – Transport Interchange Upgrade – NSW

glenfield Glenfield Transport Interchange – South West Rail Link – NSW GENERAL PROJECT INFORMATION

  • NSW government rail initiative to improve reliability and address passenger growth on metropolitan rail network
  • Glenfield railway station and bus-rail interchange upgrade
  • Construction of two rail flyovers
  • Alliance: NSW Transport, MVM Rail, MacMahon, Bouygues Travaux
  • Publics and Parsons Brinckerhoff
  • Permanent and temporary drainage design
  • Heavy rail traffic over pipe]

DESIGN CONSIDERATIONS

  • Pipe had to have RailCorp approval
  • Needed to be a heavy duty pipe, designed for LA350 rail loads and A160 road loads
  • Pipe required a design life of at least 100 years
  • Long lengths that were easy and quick to install to maximise the pipe metres installed during each session.
  • Reduction in site OH&S risks – lighter lifting weights and smaller machinery to move and install pipes achieved this result.
  • Low environmental impact through a reduced carbon footprint to complement the clients low carbon environmental footprint.

DESIGN STANDARDS

  • AS 2566 is the design standard for the ADS HDPE pipe
  • Railcorp standards TMC421 and ESC420

Stormtech – Lined Detention – QLD

Lined Detention – 5,000m3 – Emerald QLD – North-Eastern Australia  emerlad qld GENERAL PROJECT INFORMATION

  • New supermarket – Emerald, North-Eastern Australia
  • Heavy seasonal rainfall
  • Significant inflows
  • Constant traffic over the tank
  • Services and light poles intersecting the tank
  • Extreme heat conditions in summer months

DESIGN CONSIDERATIONS

  • 5,000m3 volume in one single tank
  • 12 inlets for a peak inflow of over 12m3/s
  • Reactive clay site; fully lined tank
  • Structural assessment for constant heavy traffic

StormTech – Raingarden with Stormwater Harvesting – Fawkner VIC

Raingarden with Stormwater Harvesting – Fawkner VIC Raingarden_StormTech_Charles_Mutton_Reserve_Fawkner GENERAL PROJECT INFORMATION

  • The Charles Mutton Reserve in Fawkner Victoria is home to two football ovals, a running and athletics circuit, tennis courts and lawn bowls. Moreland City Council identified a need to revitalise the reserve and future proof it against drought.
  • Consulting Engineer Spiire was engaged to prepare a stormwater harvesting scheme using water sensitive urban design principles. This is intended as a foundation for a future masterplan for the site.
  • Spiire selected Cubic M3 StormTech chambers as a rainwater harvesting solution.

DESIGN CONSIDERATIONS Stormwater_harvesting_scheme_Charles_Mutton_Reserve

  • Minimising the raingarden footprint, visibility of storages and mechanical infrastructure areas.

DESIGN STANDARDS

  • The final design included a stormwater diversion system and underground StormTech SC740 storage tank,distribution infrastructure including rising main and pumps, a raingarden to treat sediments and nutrients, storage to provide volume for irrigation cycles and UV disinfection to treat pathogens.Raingarden_Layout_StormTech_design_Charles_Mutton_Reserve
  • The expected water harvest of 20ML/year will reduce the sites reliance on potable water by 70% and reduce stormwater runoff to nearby Merri Creek.

StormTech – Raingarden with Stormwater Harvesting – Fitzroy VIC

Raingarden with Stormwater Harvesting – Fitzroy VIC GENERAL PROJECT INFORMATION Edinburgh_Gardens_Raingarden_Design_StormTech

  • Edinburgh Gardens is a 24 hectare park located in North Fitzroy, Melbourne, Victoria.
  • A Raingarden project was initiatated to provide a sustainable source of treated stormwater for the parks mature trees and sporting fields, whilst adding character to the existing landscape of the park.
  • The City of Yarra selected GHD to design the raingarden and StormTech system.

DESIGN CONSIDERATIONSEdinburgh-Gardens-Raingarden-GHD-StormTech

  • The raingarden was designed to remove 16,000 kg of total suspended solids (TSS) each year. A further 160 kg of nutrients, phosphorus and nitrogen to be removed through vegetation growth thereby avoiding release of these pollutants into Melbourne’s waterways.
  • 200kL of filtered water to be collected in StormTech underground water storage and used to irrigate existing trees. The raingarden is designed to reduce potable water by 4Ml per annum.
  • Source stormwater from the North Fitzroy Main Drain to be diverted to the newly designed terraced raingarden.
  • Filtered water to be harvested for irrigation of trees within the park and local precinct.
  • Main components of the project:StormTech_Raingarden – Diversion pipe with gross pollutant trap – Surcharge pit into 700 sq.m raingarden with StormTech rainwater catchment chambers providing storage structure – Terraced raingarden comprising StormTech chambers, appropriate planting and filter media to treat the stormwater – Overflow pit with underground pipe connected to 200 kL underground storage facility using StormTech chambers.
