Stage 2 also includes evaporative losses recharge basin is to be transferred to associated with the Stage 1 extraction pit being recycling pond where it will then be not backfilled and therefore leaving Evaporative Loss – 63 ML/yr Piped – primarily used for quarry processing groundwater exposed to evaporation. This 17 -18 ML/yr operations. Surplus water after this is to evaporative loss is 17 ML/yr. be discharged to the Murrumbidgee Evaporative Loss – 43 ML/yr River provided the solids content is <50 mg/L. Evaporative Loss – 3 ML/yr Active Existing Settling extraction Existing quarry pit – Pond (water stage functions as initial undergoes final Recharge settling pond sedimentation) basin (slimes dam) Piped Piped Piped – 243 ML/yr Infiltration – 240 ML/yr Groundwater inflows into extraction pit – varies with Stage. Ranges from 443 – 462 ML/yr. Surface Water Management – Stage 1 and 2 Surplus water after discharging to the recharge basin is to be transferred to recycling pond where it will then be primarily used for quarry processing operations. Surplus water after this is to be discharged to the Evaporative Loss – 106 ML/yr (includes losses Murrumbidgee River provided the solids content is <50 associated with rehabilitation leaving existing mg/L. If solids concentration of <50 mg/L cannot be quarry pit and existing settling pond not achieved prior to discharge then excess water is to be backfilled and therefore exposed to Piped – directed to the existing settling pond (active during groundwater evaporation. 219 ML/yr Stages 1-2) to undergo further sedimentation prior to discharging to the Murrumbidgee River. Evaporative Loss – 3 ML/yr Active Settling pond – extraction single settling pond stage Recharge incorporated into basin Stage 3 extraction area Piped Piped – 819 ML/yr Groundwater inflows into Infiltration – 816 ML/yr extraction pit – 1038 ML/yr. Surface Water Management – Stage 3 Surface Water Management – Stage 4 and 5 As per Stage 3 but whole of Stage 3 cell becomes settling pond and groundwater inflows are 678 ML/yr and 450 ML/yr respectively. Total evaporative loss from excavations exposing groundwater to evaporation for stages 4 and 5 is 169 ML/yr and 199 ML/yr respectively Surface water Management – All Stages (1 to 5) Treatment Wetlands – receives wastewater from process plant. Flows pass through wetland cells to Process Losses due to plant reduce solids concentration inefficiencies – 8 ML/yr to required level for re-use or discharge (50 ppm) Piped – 402 ML/yr Wetland evaporation – 7 ML/yr Seepage – 16 ML/yr (assuming 5 mm/d losses Murrumbidgee River – pump up to 100 ML/yr from river to Discharge of surplus water to process plant Process Plant – requires 410 ML/yr Piped as required – at least 49% Murrumbidgee River – 105 – 300 of water treated through ML/yr (depending on level of river wetlands to be reclaimed – 186 extraction) ML/yr. Water Recycling Pond – to receive water pumped from wetland. Supplies water to plant. Pipe to plant as required Water Recycling Pond – receives water from wetland and also surplus groundwater after application of groundwater to the groundwater recharge basin. 21 Attachment J – Preliminary Wetland Designs Surface Water and Groundwater Assessment: Roach Road, Wagga Wagga Quarry, Wagga Wagga, NSW. martensconsulting engineers since 1989 P0802296JR01_V2 – November 2009 Page 107 1 7 4 1 7 1 1 7 3 7 2 3 N 1 71 1 7 2 1 1 7 2 7 0 4 7 1 177 3 7 7 1 1 1 7 5 4 1 7 1 1 1 6 1 7 W E 9 1 7 0 1 7 1 2 7 5 1 7 6 1 7 7 1 7 5 7 7 1 1 7 6 1 1 7 7 7 1 4 74 4 7 1 S 17 7 5 5 1 1 7 7 3 1 1 7 6 7 9 2 1 1 0 7 3 1 7 1 7 6 2 16 1 6 6 16 5 7 1 7 16 3 7 5 1 1 7 1 5 6 1 8 7 1 1 7 3 5 7 1 8 6 7 7 1 1 1 6 0 1 7 1 6 4 9 7 5 3 1 6 1 1 1 1 7 1 6 7 1 1 7 7 1 0 1 1 7 1 6 1 6 0 7 1 2 7 6 1 4 9 6 1 1 1 2 6 4 3 1 7 7 3 4 1 1 6 1 1 7 0 7 6 1 5 1 6 2 5 7 9 9 1 7 3 2 7 1 1 7 1 0 6 7 1 4 6 1 7 4 1 1 1 7 3 7 7 7 3 1 3 2 1 1 7 7 1 7 7 1 1 6 2 1 2 8 7 7 4 1 8 5 1 7 4 7 3 1 4 1 1 7 1 7 1 7 4 3 1 7 3 1 1 47 5 1 1 7 7 7 8 7 1 1 4 7 5 4 1 1 7 7 5 1 7 4 7 7 1 1 4 5 6 1 1 7 4 1 1 7 7 7 1 3 7 3 3 4 1 1 7 7 2 4 1 1 7 5 1 7 7 7 1 5 1 5 1 7 4 5 1 7 1 7 6 6 7 6 1 7 1 5 1 7 1 7 7 0 7 1 5 1 5 1 7 1 5 1 6 7 1 7 7 2 7 6 1 1 1 0 7 7 3 5 1 1 7 5 7 1 1 1 7 7 5 6 5 7 6 1 7 1 1 7 6 6 7 1 3 7 1 7 6 1 1 7 4 1 7 5 5 1 7 1 7 1 7 7 6 7 5 1 1 4 7 7 7 1 1 2 7 3 7 4 6 7 7 1 1 1 4 1 7 7 6 5 1 5 7 7 6 1 1 4 7 7 1 1 7 1 7 7 6 1 1 1 7 5 7 7 17 1 7 6 6 4 7 3 7 1 1 1 7 74 1 1 3 7 1 7 7 1 5 4 7 7 1 7 7 1 1 17 6 9 1 1 7 1 7 7 6 7 7 6 1 1 0 8 1 7 1 8 6 1 6 7 1 7 1 5 6 7 1 1 7 7 1 4 7 7 1 9 1 1 5 7 1 6 1 9 3 1 9 1 2 1 9 4 7 7 1 6 9 5 7 4 1 7 8 1 1 9 6 7 1 1 9 5 7 9 7 7 1 1 1 9 1 7 1 8 7 5 7 1 9 9 2 0 1 8 2 1 2 0 0 7 2 8 1 3 2 0 4 1 8 1 5 8 1 5 1 8 6 1 7 8 1 7 1 8 8 7 4 18 9 2 7 0 19 0 1 0 4 1 9 1 9 1 1 2 7 0 1 9 2 7 5 2 1 9 2 3 1 0 0 7 6 3 1 9 7 4 2 1 7 1 0 9 6 5 3 1 9 6 2 2 1 5 1 7 1 1 2 1 8 7 9 0 4 3 7 2 2 1 0 9 6 7 8 9 1 2 7 1 1 7 0 6 7 9 8 9 1 2 8 1 0 1 2 7 1 9 2 1 2 1 1 7 0 2 2 7 3 4 0 5 1 5 6 8 8 7 8 8 9 8 0 2 1 8 1 1 8 8 3 8 9 1 1 1 2 0 1 1 1 1 1 1 9 0 4 1 2 3 2 1 0 0 1 2 2 2 6 4 5 0 0 0 2 2 2 2 7 2 2 1 1 9 7 1 0 7 1 2 1 6 6 0 3 0 2 2 0 0 9 2 0 2 9 2 2 1 1 8 6 5 9 9 7 1 1 4 2 9 2 5 3 1 9 2 0 9 2 1 9 1 1 2 1 0 5 2 1 7 8 4 1 8 1 9 2 0 5 7 2 1 9 7 2 2 1 1 0 2 6 1 2 0 2 0 1 7 7 7 2 0 8 1 8 0 2 8 0 1 9 1 2 1 2 0 1 0 1 7 2 1 1 6 6 2 1 1 2 2 8 0 2 2 1 2 1 2 3 1 0 2 2 1 2 0 3 4 2 1 5 2 0 2 4 6 0 1 3 2 2 2 5 0 1 2 0 2 6 4 2 1 7 1 7 2 0 2 9 0 2 2 1 0 1 2 8 7 1 2 1 1 2 9 2 1 2 1 8 0 2 2 1 2 2 1 2 2 2 6 7 2 1 6 1 2 3 2 2 2 9 1 2 4 2 (C) Copyright Martens & Associates Pty.
