SciDev was approached to treat contaminated surface water at the future site of the Stabling and Maintenance Yard for Parramatta Light Rail. The 6.2-hectare site at Camellia will be used to maintain and house light rail vehicles and a control centre to operate the new light rail system.
Treatment works were carried out to support remediation of the site which had a legacy of chromium contamination from past industrial processes.
SciDev designed, constructed, and operated a temporary water treatment plant (TWTP) that removed hexavalent chromium and other metals from the surface water on sitedown to a non-detect limit of reporting and discharged the water to sewer in accordance with the client’s trade waste agreement.
Summary
Discharge to trade waster below the limit of reporting: total hexavalent chromium <0.001mg/L.
