Offline Water Storage Facility
Key Project Facts
Project Value: $29.6m
Construction Dates: February 2017 - mid 2018
Construction Hours: 6am – 6pm, Monday to Friday
The Offline Water Storage Facility is a small dam to be constructed in the valley at Toolooa Bends (O’Connell), adjacent to the existing 50ML concrete reservoir. Together with the Standby Pump System, the storage facility will have capacity to supply approximately two weeks of raw water to the Gladstone region.
The facility will operate the same was a dam does, using the surrounding hills and dam wall to hold water. The facility is designed for water storage and not planned to collect water from a catchment. Once constructed, the facility will be filled from the Lake Awoonga supply and maintained at a nearly full capacity ready for use.
The purpose of the Offline Water Storage Facility and Standby Pump System is to provide backup water capacity in the event Lake Awoonga has to be taken offline for periods of up to two weeks. Much of the mechanical equipment at Lake Awoonga is over 25 years old and will require longer periods of time offline for inspection and maintenance in the coming years.
Gladstone-Benaraby Road and Skyhill Road Intersection Upgrade
As part of approval to construct the Offline Water Storage Facility, GAWB is first required to upgrade the Gladstone-Benaraby Road and Skyhill Road intersection, which Golding Contractors will commence from 20 March 2017 and will take approximtely 16 weeks to complete.
The 3,600 daily users of the Gladstone-Benaraby Road should be prepared for some minor delays while works are conducted.
During construction, the speed limit along this 400m stretch of road will be reduced from the current 80km/hr down to 40km/hr from 6am to 6pm weekdays and 60km/hr outside of those hours.
Two-way traffic will be maintained during the peak traffic hours of 7am to 9am and 3pm to 7pm weekdays, but single lane traffic may be required outside those hours for some works.
Once complete, the intersection will have dedicated turning lanes from the north and south and increased visibility to the south.
