Hotels, hospitals told to improve waste management
The Bali Environmental Agency (BLH) have demanded that hotels and hospitals across the island manage their domestic waste better.
Based on the agency’s findings from 2012, most of the processed wastewater samples collected from hotels, hospitals, landfills and other businesses did not reach the standard of processed wastewater suitable for disposed to open waters.
The examinations of the quality of domestic waste were taken from 50 sample locations, including 14 private or government hospitals, 23 hotels, eight landfills, two fish processing centers, a slaughterhouse, a garment factory and a cattle ranch, which are all located near open waters.
“The wastewater did not qualify to be disposed into the sea and rivers,” said Anak Agung Satriya Dewi, unit head of quality control at Bali BLH’s laboratory.
Many of the businesses do not have their own waste management because of the financial implications of building such an installation, priced at least Rp 800 million (US$82,756) per unit, said Dewi.
Most of the hotels the samples were taken from are located in Badung, Gianyar, Karangasem, Buleleng and Denpasar regencies. Dewi said that the water was analyzed as soon as it was collected as well as later at a laboratory. Some of the key parameters include temperature, Total Suspended Solid (TSS), Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Ammonia (NH3) and phosphate (PO4).
The samples taken from the hospitals were recorded to contain BOD, COD, Ammonia and Phosphate above the threshold standards.
Thus, the government has been recommended to put regulations in place that make it a necessity for businesses to have their own waste management installation, this will specifically be mentioned in their business licenses.
The agency also promised to form a special team for environmental monitoring. The agency asked the businesses to cooperate with environmental NGOs to undertake waste management; including the areas of treatment and technology.
The agency also recommended the entities build conventional waste management systems that used chemicals substances like alum (tawas) and chlorine, or biological mechanism with microorganisms, so that the processed waster water could be used for watering plants.
Dewi said that the agency would perform up to 300 examinations this year — more than the 100 examinations taken annually — on the quality of water and air.
According to a Bali governor regulation there are four types of threshold standards for water: Level 1 for drinkable water without processing, level 2 for drinkable water with advanced processing — which can be used for fish farming — and level 4 for water that can be used for agriculture and animal husbandry.
The civil servant environmental investigators (PPNS Lingkungan), better known as the Bali environmental police, still lack the facilities to perform sufficient investigations to bring environmental violators to court.
Previously, I Made Teja, a PPNS investigator, who had worked with the organization for 18 years, acknowledged that not one case had reached court throughout his career.
