The source of waste water is separated based on its types, those are black water and grey water. Black water comes from toilet waste, while grey water comes from sink, bathroom, laundry, pool, air conditioner, kitchen and all water used for hotel activities. For the kitchen waste, grease trap is necessary before the waste goes into the instalation of waste delivery. Every hotel / restaurant has collection pit as a place to temporary accomodate the liquid waste. Then the wastewater will flow in grafitation to the nearest lift Pump Station (LPS). There are 3 LPS’ in ITDC area. The LPS’ pumps will turn on automatically based on the height of the wastewater in the tank. The pump will throw the EM mixed wastewater into the Stabilization Pool, 2 km far from it.
From the LPS pump, the water will flow into Cell 1 pond, divided into 2 parts, Cell 1b. The function of this cell is to separate the oil layer and the floating solids that are still in the system of the stabilization pond. Both of the cells are separated by the fibreglass layer in the upper side, so it is easier for cleaning of floating grease / oil/dirt. The water then flows in gravitation to the Cell 2a and 2b. The java Tilapia and Nile Tilapia fishes are spread into the mini pool as the biologic indicator of wastewater. The maximal process is in the Cells 2b because it has bigger capacity, the work of bacteria is more maximal. Then the water flows into Cell 3. This pond will further neutralize the condition of wastewater before it goes into the next processing. The retention time of wastewater in the stabilization pond is at least 28 days. Nowadays the wastewater has been in the pond for 33 days, which means that the longer of the wastewater stays in the stabilization pond the cleaner wastewater will be.
the beauty of the beach of nusa dua has a special attraction for tourist who visit and provide an unforgettable experience. to maintain environmental sustainability is the itdc applied sustainable area management priciples in nusa dua area which includes : maintaining hygiene and cleanliness of the environment surrounding beaches and mangroves around area. area of waste grouping consisting of wastewater and solid waste (garbage). wastewater management system uses swimming stabilization, aeration area of about 15 hectares. the results of processing water redistributed as irrigation water for garden watering needs around the region, with sales highest in the dry season is 3,748 m3 / day. solid waste management (garbage) conducted by disaggregated by type of waste, inorganic waste is managed by a private provider of waste management services by the repective tourism facilities, and processed.

nusa dua reef foundation is a non-profit organization focused on research, education, and conservation of coral reefs. our vision is to create multi-stakeholder concerns to conserve coral reefs of the world, especially in bali, to reduce the global warming impact.
currently, we have placed 62 artificial reef sculptures, 117 artificial reef structures at six locations underwater off nusa dua and tanjung benoa beaches. furthermore, to ensure they grow well and healthy, we maintain the transplants through regular monitoring, aided by a number of volunteers. so far, badung underwater cultural park, a coral reef rehabilitation program has received global. up till now, these activities are still going.
together with government, tourism industry, and other key stakeholders, we initiated the development of a marine protected area (mpa) of badung. survey and various socialization activities and approach to stakeholders is being conducted in effort to build a common understanding of the mpa plan.
