The Lagoon As An Environmental Preservation Concept
Conserving The Environment Attracts Visitors And Increases The Economic Value Of The Tourist Resort The approximately 4,000 hotel rooms and other facilities of Nusa Dua produce around 4,000 to 5,000 cubic meters of wastewater per day. To preserve the ecosystem within the zone, BTDC provides a lagoon which functions as a wastewater recycling plant with a capacity of up to 10,000 cubic meters per day. This lagoon was built in 1976. The quality of the water provided by the lagoon is acceptable for watering plants and gardens, common area landscapes, hotel landscapes and golf courses. The total land area of the lagoon used for wastewater processing is approximately 30 hectares. At present, 50% of the total allocated area has been utilized, including 15 hectares for wastewater installation (cell 1,2,3) and approximately 1 hectare for irrigation water installation (pool, sedimentation and filtering). The wastewater processing system used by BTDC at the lagoon is a Waste Stabilization Pond, which is a system that maximizes the occurrence of natural oxygen in the pond with assistance from wind and sunshine. The wastewater that is produced is ready to be used as irrigation water. To increase the quality of water after the natural oxygen process in the pond, the water is processed again in the pond with 8 aerators. The water is given supplementary oxygen for 5-8 hours per day in order to speed up the oxidation process and increase the quality of the irrigation water. The sedimentation pond is where the muddiness of the water is decreased before it enters the filters. The filter pond is where small particles are filtered out so that the irrigation water becomes clear. After the filter process the water is contained in a reservoir, where it is ready to be distributed to clients through pipes that have been installed to carry it to gardens and landscapes throughout the Nusa Dua Tourist Resort and hotels. |
