Table 3.1 Project screening tool checklist for stormwater reuse in public, open- space irrigation Topic Question Response Purpose 1. Does the scheme involve stormwater irrigation of LJ Yes — (intended public parks and gardens, roadsides or sporting next question end uses of facilities (including golf courses)? LJ No see — the Appendix 6 stormwater) The 2. Is the catchment land use limited to residential or LJ Yes — commercial uses, with no significanta additional catchment next question pollution sources, such as: LJ No or not known agricultural or industrial land use see Section A5.1 — a significant proportion of the catchment comprising corroding roofs extensive construction activity, eroding stream banks or other significant sources of sediment on-site sewage management systems (eg septic tanks) wastewater (eg sewage) treatment plants discharging into the catchment contaminated sites or areas with acid sulphate soils? 3. Is the number of sewer overflows reported by the LJ Yes — local water utility in the catchment relatively low, next question that is, below 14 per 100 km of sewer pipe per LJ No or not known year as an average over the past five years? see Section A5.2 — LJ Yes or not known 4. Are there any other stormwater harvesting or water extraction schemes in the catchment? see Section A 5.3 — LJ No — next question The 5. Will the amount of stormwater withdrawn from LJ Yes — the scheme be less than 10% of the mean annual stormwater next question stormwater runoff volume from the catchment LJ No see — above the collection point? Section A5.3 6. Is the stormwater drain where the stormwater is LJ Yes — collected free from tidal influence, and is the next question catchment free from significanta areas of high soil LJ No see — salinity (eg > 2dS/m) or known salty lakes? Section A5.4
