Typical international figure for headroom:10%, outage: 5-7.5%
Headroom/Outage reduced to 5% for Primary Schemes study because:-
2 inclusion of all available zoned residential lands results in 13.5% increase over projections planning publication projections;
2 high growth NSS’ EGS 2 Option 1 scenario would suggest that an underestimation of growth in the planning period would be most unlikely.
Headroom allowance of 10 % applied to all Secondary Schemes & Un-serviced areas due to greater uncertainty in these areas
Headroom applied to ‘Accounted For Water’ Demand only i.e. not UFW or Strategic Industrial Allowances
