Overview of Environmental Management in Singapore Poon Chiew Tuck Senior Engineer Pollution Control Department National Environment Agency
Introduction Singapore developed industrial base & achieved high economic growth in short span Programmes implemented at early stage to protect environment
Environment quality compares well with best cities in the world Major air pollutants within international standards Inland and coastal waters support aquatic life
Air Quality Descriptor 0 – 50Good 51 – 100Moderate 101 – 200Unhealthy 201 – 300Very Unhealthy Above 300Hazardous Pollutant Standard Index (PSI)
Management Strategy • Prevention • Enforcement • Monitoring • Education
Prevention • Planning Control • Land use planning • Judicious siting of industries • Environmental Infrastructure • Comprehensive sewerage system • Efficient solid waste system • Pollution Control • Air and water pollution control measures
Land Use Planning • Consultations between URA and NEA on land use planning • Land is zoned for specific uses such as residential, commercial, industrial, etc. • Environmental controls are factored into the planning
Environmental Control • Safeguarding land for drainage, and facilities for collection, treatment and disposal of wastewater and refuse • Protection of water catchments • Compatibility of land use
Siting of Industries To optimise land use • site industrial estates for clean and light industries close to residential areas • site general and special industries farther away from residential areas in Jurong and Tuas Industrial estates, and on Jurong Island
Sewerage System • Separate sewerage system for wastewater and open drainage for rain water • 6 water reclamation plants • 3,140 km sewers • More than 100 pumping stations • served all industrial estates & almost all residential premises except for isolated pockets of residential premises with on-site sewage treatment plants
SEWERAGE SYSTEM HOUSEHOLDS COMMERCIAL PREMISES WATER RECLAMATION PLANT INDUSTRIES EFFLUENT OUTFALL MANHOLE PUMPING STATION PRETREATMENT PLANT SEA SEWER
Sewerage System areas served
Solid Waste Management • Daily refuse collection service • 90% of wastes disposed off at 4 incineration plants • 10% of wastes disposed off at the off-shore Semakau sanitary landfill
Refuse Disposal Facilities Senoko IP Closed Lorong Halus Dumping Ground Ulu Pandan RIP Tuas IP Tuas South IP Semakau Landfill
Air Pollution Control • Licences for scheduled premises • Industries designed or provided with pollution control equipment to comply with allowable emission standards for air pollutants • Fuel burning equipment to use fuel of specified quality • Open fire prohibited
Vehicular Emission Control • Set stringent emission standards for registration of new vehicles • Require use of cleaner fuel • Require mandatory periodic inspection of in-use vehicles • Take stringent enforcement action against smoky vehicles • Promote education on proper vehicle maintenance to prevent smoke emission
Water Pollution Control • Trade effluent pre-treated to allowable discharge limits for discharge into a public sewer or watercourse • Industries may pay tariffs for the discharge of trade effluent containing biodegradable pollutants into the public sewer • Containment facilities provided for storage tanks of oil and chemicals
Management Strategy • Prevention • Enforcement • Monitoring • Education
Enforcement Conduct regular checks on industries • Air pollutants to comply with emission standards • Trade effluent to comply with standards for discharge into sewers/watercourses • Control, management and disposal of hazardous substances and toxic industrial wastes
Management Strategy • Prevention • Enforcement • Monitoring • Education
Monitoring • Regular monitoring of ambient air quality, and inland and coastal waters • Assess adequacy and effectiveness of control programmes • Monitor the trendof air and water qualities • Carry out regular review of policies and emission standards with extensive consultations with the public and industries
Management Strategy • Prevention • Enforcement • Monitoring • Education
Education • Work with industries as partners to move towards self-monitoring and co-regulation • Dialogues with industries, professional institutions, etc • Training courses for professionals, industries, etc • Seminars, workshops, etc, for industries, businesses, etc • Public campaigns, e.g. Clean and Green Week
