Construction of a four megalitre reservoir to be built off Apex Road adjacent to the existing reservoir in Bottlebrush Park is set to begin, with the contractor, Hornicks Constructions, securing the site from January 29. The new reservoir is required to address water security and to cater for the predicted population growth within the town of Gunnedah. The project cost is $2.5 million and will be fully-funded by Council. The project involves the construction of a concrete reservoir, which will be approximately 27.5 metres in diameter and approximately eight metres high. The reservoir has been designed to have the same roof level as the existing reservoir and will incorporate aesthetic improvements, including white roof sheeting to reduce glare to surrounding residences. The project is expected to take 36 weeks. Working hours will be undertaken between 7:00am and 6:00pm, Monday to Friday and between 8:00am and 1:00pm on Saturdays.
The base slab for the 4ML Apex Road Reservoir was poured on Thursday, 14 June – comprising of 95m3 of concrete and approximately nine tonnes of reinforcing steel. Due to the cold weather a variety of measures have been put in place to allow the concrete to cure and to prevent it from shrinking, or cracks forming on the surface. The first concrete wall pour is scheduled for Monday, 16 July – approximately 70m3 of concrete. The aluminium roof framing and sheeting is scheduled for late August 2018, with the project on schedule to be completed by November 2018.
The three wall pours have been done, each approximately 70m3, 200m3 total of concrete for tank walls. Aluminium roof framing, sheeting and perimeter fencing scheduled for mid-October. Practical completion scheduled for early November. There will be an official opening in November.
The concrete construction is complete, which was followed by the installation of the roof. The enduro green (light green) colour chosen for the roof will minimise any reflection affecting properties in the vicinity and blend into the natural environment.
The structural integrity of the reservoir tank will be tested for leaks following internal cleaning and disinfection of the tank. Once the testing is complete the building of a perimeter fence, an external staircase and the construction of a service road and the restoration of the park will begin.
Completion is scheduled for November, with the project on budget and schedule.
The new reservoir has been filled up with water for stress testing. The new access ladder and electrical installation is in progress.
The concrete construction and roof installation is complete on Apex Rd reservoir. The reservoir has successfully undergone hydrostatic testing for water tightness. The road works are now to commence, with pavement, kerb and guttering and asphaltic concrete (AC) seal to be constructed.
The staircase has been completed and the next step is the perimeter fencing. The reservoir will go into service as soon as water quality can be confirmed.
