Introduction
  • Singapore developed industrial base achieved
    high economic growth in short span
  • Programmes implemented at early stage to protect
    environment

3
  • Environment quality compares well with best
    cities in the world
  • Major air pollutants within international
    standards
  • Inland and coastal waters support aquatic life

4
Pollutant Standard Index (PSI)
5
Management Strategy
  • Prevention
  • Enforcement
  • Monitoring
  • Education

6
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

7
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

8
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

9
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

10
Land Use Zoning
11
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

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

17
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

21
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

25
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

26
Checking air emission levels at a factory
27
Management Strategy
  • Prevention
  • Enforcement
  • Monitoring
  • Education

28
Monitoring
  • Regular monitoring of ambient air quality, and
    inland and coastal waters
  • Assess adequacy and effectiveness of control
    programmes
  • Monitor the trend of air and water qualities
  • Carry out regular review of policies and emission
    standards with extensive consultations with the
    public and industries

  • Monitoring
  • Education

32
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
