Abstract

The karst region of Maros has water system that is conducive both under the cave and emerge as the river surface, such as watershed Bantimurung. The upstream of DAS Bantimurung is used as a place of tourism , agriculture and irrigation for raw water in Maros PDAM. To that end, economic valuation needed to be done to water resource, in the form of total economic value. The amount of discharge water contained in Maros Karst area for 20 years (1990-2010) tended stands at 7,00 m 3/s, with the lowest water discharge occurred in September, approximately 1,00 m3/s and the highest in January at 20 m3/s. Direct use value amounted to Rp 385,479,052,214 then indirect use value was Rp 13,251,588,000 and the non-use value was Rp20,016,148,000, so the total economic value, TEV, of each year was Rp418,746,788,214. For sustainable use of river water underground of Karst Maros that acquired the entire agricultural irrigation water needed in Maros regency was 5,32 m3/s and the PDAM amounted 2,037,943 m3 then available water in Karst Maros was 220.8 milyar m3 per year, so there was still the water surplus of 15,10 milyar m3 for each year
