The Department of Local Government, Water and Volunteers requires an experienced Design Consultancy to develop detailed designs for the Cherbourg Bert Button Water Reservoir. Timeframes are extremely tight due to funding conditions. The timeframes set out in the invitation documents are immovable.

Cherbourg is an Aboriginal community of the Wakka Wakka people. Located in Wakka Wakka tribal boundaries, near the border of Gubbi Gubbi territory. It is located 267 kms northwest of Brisbane and located in the South Burnett region. The community has an estimated population of 1,190 residents according to the 2021 census, though DASC suggests the actual population is closer to 1,800. With projected population growth to 4000 by 2070, the demand for essential services, including safe and reliable drinking water, is expected to increase significantly.

The Cherbourg Water Treatment Plant (WTP) is critical for supplying potable water to the Bert Button Reservoirs which supplies water to 5 houses, 1 business, 1 men’s shed and 1 Abattoir. Established in 1970s, the existing 2 Bert Button reservoirs are now completely deteriorated with extensive corrosion on the pipework and are currently inoperable. This has contributed to up to 20% loss of water. The cracks in the Mains have further introduced the risk of bacteria from soil contaminating water.

The scope of works is as follows.

Develop a detailed design for the following construction scope of work.

• Demolish & remove existing two reservoirs.

• New 150,000L concrete reservoir (with concrete roof). The reservoir is to have access to stairs and lockable access to hatch

• New clear water rising main from the WTP pressure pumps to new 150KL reservoir Approximately 800m in length

• New pump shed with room to accommodate new sodium hypo dosing system

• An automated system with an analyser that will test the outgoing reservoir water for chlorine and PH and additionally dose sodium hypo to maintain chlorine residual

• Provision to integrate the Reservoir level, sodium hypo dosing system and pressure pump status to existing/new Water Treatment Plant (WTP) SCADA system via digital network

• Upgrade the electrical system to booster pumps

• Replace fencing with 2.4m high security chain-link fencing with angled top to hold 3x strands of barbed wire (approx. 130m length) including twin hinged vehicle access gates

• In the Bert Button reservoir compound - Lay concrete mowing strip 300mm wide around base of fence & lay sealed driveway & hardstand 4.5m wide by 15m long = 68m2

• Install fire hydrant line for all properties ensure compliance with AS1850

• Install new water main from new Bert Button Weir reservoir to intersection between Lookout Road and Murray Road.

• Install new water main parallel to Murray Road running south-east to property boundary approx. 200m east of Abattoir

• Install new isolation valves (8).

• Connect the new water main via poly pipe to all homes on Murray Road including Men’s Shed and Kennels – 4 total

• Connect new reservoir to 2 houses and 1 business via poly water main near the Bert Button lookout.

• Connect the new water main via poly pipe to the house next to the Water treatment plant.

• Installation of smart water meters is required for all reconnection of existing water services.
