114 Eurobodalla Integrated Water Cycle Management Strategy Opportunity Social Environmental Enhanced management of existing onsite facilities Enhanced management of existing onsite facilities with greywater reuse Centralised management of effluent from onsite facilities Provision of full reticulated sewerage system Local treatment and management Transfer to Batemans Bay system Local treatment and management Transfer to Batemans Bay system Improves air quality and visual character Enhances aesthetic appeal for the local area, good for tourism and recreational activities Improves air quality and visual character Potential disturbance during construction period Enhances aesthetic appeal for the local area Decreases demand for water, increases security Solution would be tailored to match local requirements Potential short term disturbance during construction period Limited additional treatment infrastructure required Existing resources can be utilised Potential short term disturbance during construction period Solution would be tailored to match local requirements Larger capital investment required Short term inconvenience for residents during construction i.e. noise, vehicle movement Limited additional treatment infrastructure required Existing resources can be utilised Short term inconvenience for residents during construction i.e. noise, vehicle movement 9.2.4 Integrated Water Cycle Management Scenarios Reduces impact to local aquifer and the environment Reduces impact to local aquifer and the environment Maximises water resource use Would encourage local reuse and recycling Less overall environmental impacts than conventional gravity systems Possible environmental impact during construction Less overall environmental impacts than conventional gravity systems May allow for regional reuse Improves quality of effluent discharged to environment Increases opportunities for effluent reuse Possible environmental impact during construction Significantly reduces likelihood of groundwater contamination Improved quality of effluent discharged to environment Increased opportunities for effluent reuse Possible environmental impact during construction Significantly reduced likelihood of groundwater contamination Using the bundling process, the above water management opportunities can be combined into integrated scenarios. Table 9-3 presents examples of integrated scenarios. Other scenarios may be developed and considered in subsequent study phases.
Eurobodalla Integrated Water Cycle Management Strategy Table 9-3 Integrated Scenarios for South Durras Improved management of existing water supply Harvested roof water supplemented with reticulated water Provision of full reticulated water system Minimal Traditional Solution Integrated Scenarios 3 4 5 Local water source Regional water source Local water source Regional water source Improved management of existing on-site facilities Enhanced management of existing on-site facilities Enhanced management of existing on-site facilities with greywater reuse Centralised management of effluent from on-site facilities with local treatment Provision of full reticulated sewerage system Local treatment and management Transfer to Batemans Bay system Minimal Improved management of existing water supply and improved management of existing onsite facilities. Traditional Provision of reticulated water systems from the regional supply, and the provision of full reticulated sewerage systems with transfer to the Batemans Bay system. Integrated Scenario 3 Harvested roof water supplemented with reticulated water from the regional supply, and centralised management of effluent from on-site facilities with local treatment and management. Integrated Scenario 4 Harvested roof water supplemented with reticulated water from a local supply source and enhanced management of existing on-site facilities. Integrated Scenario 5 Harvested roof water supplemented with reticulated water from a local supply source and enhanced management of existing on-site facilities with greywater reuse. 115
