Construction of a replacement sewer pump station and rehabilitation of earthenware pipes.
Pump Station and Sewer Installation: Construction of a 5.5 metre deep new pump station and change over from existing including all alterations to incoming pipework. Pipework uo to four metres deep in wet conditions required shielding and shoring. Refurbishment of existing three metre diametre eight metre deep pump station, which required re-fixing of discharge bends to base pum station and replacement of riser pipes from discharge bend through the valve chamber.
Environmental Management: Existing pump station flushed and sucked to waste with use of sucker trucks. All dewatering discharge pumped to nearby stream through decant system. No non-compliance notices on the contract.
Reinstatement: Contract undertaken through the winter months. Full reinstatement unable to be completed due to wet conditions – site made safe with silt fences and mulch until full grassing was able to be completed.
Dewatering: A six inch dewatering system and sump pumping was utilised to facilitate pipeline installation.
Public Liaison: Some of the work was completed through private property. Close liaison was kept with the landowner to achieve final sign-off.
Safety: Weekly toolbox meetings and safety plans were developed for different stages of construction.
