(b) Using the given data and information for an area in NSW, estimate the following per year: (4 marks) Quantity of available runoff water (excluding roof water which is collected by rainwater system); Water demand by the residents of the area; Quantity of water collected from roofs Water shortage • Quantity of imported water Assume the stormwater generated is used for supplying the water to the domestic consumers. Given data: • For Scotland Island (nearest rainfall station is located at Palm Beach Coasters Retreat) • Rainfall = 1180 mm/yr • Area = 50 ha • No. of residential houses = 328 • Roof area = 35 m² Runoff coefficient = 0.14 . Average water demand = 2501/person/day Average size of the HH = 3.11 person Rainwater roof collection efficiency = 0.75
