Upgrade planned for sewage pumping stations
Gosford Council has accepted a tender to upgrade three sewage pumping stations in Woy Woy.
Another tender has been let to upgrade pumping stations at Daleys Point and Ettalong.
The "augmentation" will be carried out under Council's extensive Sewage Pumping Station Upgrade Program.
The upgrade will ensure that each pump station and associated catchment will be able to accommodate a minimum four hours emergency storage in the event of power failure during average dry weather flow conditions.
The four hours provides sufficient response time for Council's operations staff to implement contingency plans in the event of a pump failure, according to a council staff report.
The council was told that three Woy Woy sewage pumping stations needed upgrading.
WW3 would need a below-ground concrete retention tank to ensure the station would incorporate the minimum required storage.
Pumping stations WW6 and WW13B had sufficient emergency storage capacity of greater than four hours and did not require additional storage facilities.
However, their pumps, pipe work, valves and fittings were approaching or had exceeded their life expectancy and required immediate refurbishment.
The company chosen to undertake the construction of a retention tank at WW3 and refurbishment works at WW3, WW6 and WW13B was Carey Constructions Pty Ltd of Abbotsford.
The construction period is thirty weeks and the work is scheduled to commence in January 2012.
The second tender was let to Rivers Constructions Pty Ltd in West Gosford for the refurbishment of pumping stations DP2 at Daleys Point and E5 at Ettalong.
The work to be undertaken includes the establishment and maintenance operation of temporary sewage by-pass facilities, the removal and replacement of all pumps, pipe work, valves and fittings and the removal and disposal of decommissioned materials and fittings from the sites.
The construction period is 26 weeks and the work is expected to commence in January next year.
