Ballarat Water Supply Network Model (CHW)

Purpose:

1) Develop population forecasts

2) Planning of pressure reduction works as part of an overall program to address unaccounted water

3) Planning for population & demand growth

System Complexities:• Three sources of supply (variable WQ)• Six main pressure zones plus sub-zones• 18 No. PRV’s plus 2 No. PCV’s• 22 No. storages and 8 No. pump sets• The model was validated against SCADA.

Township Development Plans (WW)Portland, Port Fairy, Hamilton & Heywood

Purpose:

1) Strategic and capital works planning

2) Efficient servicing and operations

System Complexities :• No. pipes ranged from 300 to 2000• Calibrated to monitored flows & pressures• One town under Stage 4 restrictions• Three towns under PWSM• Developed data monitoring and collection program

Bendigo Augmentation Strategy (Coliban)

Purpose:

1) Determine most effective and efficient means of operating the system

2) Develop future system improvement options:- 5 stages over 25 years

System Complexities :• Extension of the network to 5 satellite townships• Pressure, security of supply, fire flow• Water quality calibration & modelling• Leakage reduction• Develop strategy model user manual and training

WMP Hydraulic Design Review (Coliban)Purpose:1) Independent performance review of hydraulic design and as-

built system2) Confirmation that agreed levels of service can be supplied

System Complexities:• WMP system ~10% of Victoria (2M Ha), 8000km pipeline, 53

pump stations, 71 storage facilities• Review how models were used to size pipes and

their ratings, and design pump stations & storages• Identification of shortfalls, deferral opportunities

with verified via systematic consultative process• Improvement opportunities identified, e.g. security

of supply, trigger points, modelling potential
