Stockland’s development of the Willowdale Estate in Leppington required Temporary Sewer Pump Out Tanks to facilitate and capture sewerage before trunk mains networks were commissioned. Jonishan were awarded the contract for installation of the facility which was monitored by a control panel with Sydney Water telemetry.
The project required the installation of 5 inline storage tanks with pump out facilities and construction of hard stand and access roadways to suit tankers. The facilities had a sewer overflow using 900 x 900 GSIP, a discharge headwall and customised galvanised grates and access hatches. Jonishan constructed the road using DGS40, DGB20 and z coat primer. The electrical panel was linked to level switching with telemetry for monitoring and warnings.
