Customer base snapshot 2014/2015

Demand Growth forecast

Demand Growth forecast

• Factors affecting growth– Major customers play dominant role– Domestic usage = 70% of total– Natural population growth, inward migration, system losses

• Projected growth in demand– Projected demands contractually based on customer forecasts– Projected population growth of 3 million from 2010 to 2030– With an annual growth of 1.75%:

The reality: AADD abstraction growth - excludes Authorised Users and WDM. Available raw water infrastructure is behind growth

Non Revenue water(15% in 15 yrs)

Response to Limitations

• WDM plans– Municipal customers required to submit WDM plans when applying for

new connections (offset WDM savings against new demand)– WDM initiatives not intended to restrict development– Typically, areas of saving and development nodes are geographically

separate– In future, customers will be measured on WDM performance

• Potential for deferral of some capital expenditure, but:– Major projects have long lead times– Some existing infrastructure approaching full utilisation at peak periods– Require ‘headroom’ to take major infrastructure out of service for renewal

• Response– First see effectiveness of WDM initiatives by location– Complete current projects but defer future projects

Augmentation & Renewal Planning

• Augmentation– Increase capacity to meet future demands (quantity & quality)– 20 year view of projects based on 35+ year view of demands

• Renewal– Extend life of existing assets (replace, refurbish, upgrade)

• Integrated asset management approach– Many projects combine augmentation and renewal (eg pipelines)– Integrate at plant, site and system level
