Sewage Option 3 -- Transfer of Southern Catchment to Tomakin Plant
- Transfer of sewage from North Batemans
Bay along Spine Road
- Inflow and infiltration minimisation
- Enhanced wet weather storage for priority
pump stations
- Transfer of sewage from Malua Bay area
through a new rising/gravity main to
Tomakin plant
- Optimise Tomakin STP to cater for the
Maula Bay load in addition to future local
growth requirement
Optimisation of
existing assets
Transfer of effluent
only from Northern
Batemans Bay to
outfall. Possibility of
reuse at growth
areas
Use of better outfall
More reuse
possibilities at
Tomakin than
Batemans Bay
