Water Resources Management Plan

• Balance between water supplies and water demands

– “Supply demand balance”

• WRMP updated every 5 years.
• 25 year planning period 2015-2040
• Sets out potential options to reduce deficit and

balance supply and demand.

• Central Region supplies

– 870Ml/d average & 1115Ml/d peak.

• Deficit estimated in order of

– 140Ml/d average & 130Ml/d peak by 2040.

Future Challenges

• Increased water consumption per person
• Population growth & increased single
• ccupancy
• Reducing abstraction to improve the

environment

– Sustainability Reductions

• Pollution
• Climate change

What does this mean for us?

• Increase supply capacity or reduce demand?
• Options

– Demand Management (Nic Gilbert’s workshop) – Transfers – Surface Water – Groundwater – Other

• Water recycling, desalination, catchment management

Workshop exercise

• How do you choose the best option?
• Split into 2 groups
• Discuss options
• Rank the options from 1 to 8
• Nominate someone to feedback

How do you choose the best option?
