Point Boston Peninsula is a 10 year master planned community development that stretches over 750 hectares of natural peninsula just 12 kms from Port Lincoln in South Australia. Special covenants have been developed to ensure that a harmonious relationship between the natural environment and the development is maintained. Point Boston Peninsula will be developed in 4 grouped settlements, retaining much of the natural landscape in between. Each offers about 250 opportunities to build conventional homes or duplex accommodation.When dealing in remote locations, water recycling is a mandatory consideration for installations wanting to make the most of their available water resources.
Point Boston Peninsula is based on the highest of ecologically sustainable practices, with building guidelines designed to ensure all development is sensitive to the location. Ecological sustainability is a keystone principle of the development, particularly in respect of water cycle management. The development requires 174 ML of water per annum and is to be self sufficient in water resources except for the need for an average of 6% supplementation from the SA Water regional distribution network rising to 17% for the lowest rainfall year on record.
This high level of water self sufficiency is to be achieved by capturing as much roof rainwater runoff as practicable in tanks on each lot for potable use within the house; treating household wastewater to a high standard in an aerobic unit on each lot; collecting the treated effluent in a pressure reticulation network; passing part of the treated effluent through a tertiary polishing and disinfection plant and recycling it to houses for reuse in toilet flushing, clothes washing, garden watering and other non potable external uses.
Cullys and EcoNova were engaged to deliver the tertiary ultra-filtration, disinfection water recycling facility and system wastewater management (WRF) with a capacity of 24 kL/h, built in two 12kL/h stages. The plant will polish the secondary effluent collected from the household aerobic units to recycled effluent quality for unrestricted non-potable domestic uses specified in the Australian Guidelines for Water Recycling 2006 (AGWR). The purpose of EcoNova’s tertiary treatment plant is to remove pathogens to an extent that makes the water safe for household non-potable uses. The WRF is being supplied, installed & operated by EcoNova & includes the following process train:
- Secondary effluent inflow covered balancing tanks (by others).
- NovaUltra™ 0.01 ~im absolute ultra-filter.
- UV disinfection.
- Chlorine disinfection.
- Treated water balancing tanks and recycled water distribution pump station (by others).
- Stabilisation and reduction of the ultra-filter backwash suspended solids by aerobic digestion in a NovaPro™ Membrane Bioreactor (MBR) for periodic removal by tanker to an approved biosolids receival facility.
- Return of the MBR filtrate to the treated effluent inflow balancing tanks.
In addition to our involvement in the water and waste water component. Cullys was also responsible for the design, manufacturing, programming and integration of the electrical and control components. The plant operates fully automatically using a programmable logical controller (PLC) which also allows for remote monitoring and management to reduce onsite operator involvement.
