REHABILITATION OF THE CANTERBURY BANKSTOWN SUBMAIN
The Canterbury Bankstown Submain was constructed between 1919 and 1927 and primarily drains residential flows from Belfield through to Arncliffe, where it merges with the Main Western Carrier at Wolli Creek.
Water Infrastructure Group started work in March 2011 to rehabilitate 2.1 km of the 1.83 metre diameter submain between High Street, Canterbury and the Wolli Creek Aqueduct, Earlwood.
REHABILITATION OF THE BONDI OCEAN OUTFALL SEWER
The Bondi Ocean Outfall Sewer (BOOS) was the first ocean outfall sewer of its type to be designed and built in Australia. Designed and built by the NSW Public Works Department from 1880 to 1889, the BOOS was intended as an alternative means for disposing of the City's sewage which was then being drained into Sydney Harbour. Water Infrastructure Group started work on site in January 2010 and rehabilitated a 911m section of the BOOS which runs from Bellevue Hill through to North Bondi.
REHABILITATION OF THE BERKELEY CARRIER
Water Infrastructure Group completed rehabilitation works for sections of the Berkeley carrier in the Illawarra Region for Sydney Water.
Water Infrastructure Group has implemented extensive measures to ensure the protection of this sensitive environment, including a specific sand dune rehabilitation plan, which has been developed in conjunction with Wollongong City Council, and the exclusion of entry into the lagoon area.
EAGLE FARM RISING MAIN REHABILITATION
The Eagle Farm rising main runs from the Eagle Farm pump station to Luggage Point WWTP in Brisbane. Approximately 60% of Brisbane's wastewater flows through this part of system.
Brisbane Water identified that a 9.5 km section of the rising main required an internal rehabilitation to maintain the structural integrity of the pipeline. Water Infrastructure Group designd and installed a continuous, corrosion resistant Panel Lok lining system for the 1370mm diameter sewage pressure main
HAY STREET CHANNEL RELINING
Water Infrastructure Group relined the Hay Street stormwater channel, which runs under the busy intersection of Hay and Harbour Streets near the Sydney Entertainment Centre forecourt in Haymarket.
The channel was constructed by the Sydney City Council in 1863 and is one of the first combined sewers constructed in Sydney, and possibly Australia. The purpose of the channel was to improve public health by diverting stormwater and sewage off the streets and discharging it into the harbour.
LIVERPOOL TO ASHFIELD PIPELINE REHABILITATION
Water Infrastructure Group is undertaking CCTV inspection and reporting works of Sydney's wastewater and stormwater infrastructure for Sydney Water.
Water Infrastructure Group has already completed nearly 2,240,000 metres of CCTV inspections in the past four years, with approximately 50,000 metres of CCTV surveys completed monthly. Approximately 13,000 separate pipelines were surveyed in 2010/2011 alone.
REHABILITATION OF SEWER MANHOLES
Moreton Bay Regional Council had identified a number of deteriorated sewer maintenance holes with various extents of corrosion. The Council decided to rehabilitate these maintenance holes to improve the structural integrity and seal against infiltration and leakage.
Water Infrastructure Group rehabilitated the sewer manholes using SewperCoat®. SewperCoat® is 100% pure calcium aluminate premix specifically developed for sewerage structures.
SWSOOS REHABILITATION
The Southern and Western Suburbs Ocean Outfall Sewer (SWSOOS) is Sydney Water's largest wastewater system, serving 40 per cent of Sydney's population.
Water Infrastructure Group formed the EMT JV with McConnell Dowell Constructors to undertake the technically challenging structural rehabilitation and lining of 10km of the corroded SWSOOS. This was the largest sewer rehabilitation project ever undertaken in Australia.
WESTERN BRANCH MAIN SEWER REHABILITATION
The Western Branch Main Sewer (WBMS) was built in the late 1890s and is the major trunk sewer servicing the inner west suburbs between Drummoyne and Homebush, Sydney.
WBMS is classified as an important heritage structure, listed on the State Heritage Register. Internal inspections identified the need for rehabilitation to ensure the continued operation of the asset.
