1. STORMWATER NETWORK - DEMAND ASSUMPTIONS & CONVERSIONS

   1.1. Service Catchments
The Stormwater network in Noosa Shire is an open network divided into to a number of
catchments focussed on urban land within the Priority Infrastructure Area (PIA). The
catchments are identified on the Stormwater network maps and summarised in Table 1.1.

   1.2. Demand Assumptions & Conversions
The demand assumptions for the Stormwater network have been based on the ultimate
urban developable lot area obtained from GIS data for urban IPA Planning Scheme Zones
within each PIA service catchment. The respective conversion rate applicable for each urban
development zone is summarised in Table 1.2.
