Transcript of Water Demand Forecast
Projected water demand
Total projected water demand to 2029 is summarised in table 2.3 and further detailed in the financial
model. Estimated water demand for the year 2003 has been used as the baseline for the projections.
The water demand projections have been prepared on the following basis:
universal metering will be achieved by 2007;
continuity of supply (i.e. 24 hour service) will be achieved by 2007 for all towns.
in the long term, average domestic consumption will be no greater than 120 l/h/d (litres
per head per day), specifically
(a) where existing domestic consumption is less than 120 l/h/d, it has been
assumed to remain constant at existing levels until 2019 and then increase
linearly to reach 120 l/h/d by 2029;
(b) where existing domestic consumption is greater than 120 l/h/d, it has
been assumed that it will fall as a result of increased metering and tariff
increases to 120 l/h/d by 2007 and remain constant thereafter;
institutional consumption will remain constant in terms of equivalent litres per head day;
industrial and commercial consumption will remain constant in absolute terms with any
increase in water consumption as a result of increased industrial activity being offset by
further efficiency savings;
the use of private water sources by industry will remain as existing;
non-revenue water will decrease to approximately 20% of water into supply by the year
2022 as a result of the introduction of a pro-active leakage detection and management
programme and selective rehabilitation of the network. In towns where existing services
are discontinuous, some short term increase in non revenue water (specifically physical
losses) may be expected following the introduction of 24 hour services. In part this will be
offset by rehabilitation of the network;
service coverage will expand to approximately 100% of town by 2022.
