Broad StrategyNeed to strike a balance between• Promote economic and industrial

growth• Protection of the environment

Anti-Pollution Unit – 1970Ministry of the Environment – 1972Programmes implemented to protect the

environment

Key Elements of Strategy

• Long term planning• Preventive control of environmental threats• Monitoring of environmental quality• Effective legislation & enforcement• Provision of environmental infrastructure• Use of environmental technology

Land Use PlanningUrban Redevelopment Authority

• National Authority for land use planning

• Prepares Concept Plan and Development Guide Plans (DGPs)

• Land is zoned for specific uses such as residential, commercial, industrial, etc

• Environmental controls are factored in Concept Plan and DGPs Protection of water catchment Provision of environmental infrastructure Compatibility of land use

Preventive Controls

• Judicious siting of industries

• Development and building plan control

• Inspection of completed premises

Siting of Industries

• 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

Siting of IndustriesEvaluates pollution impact of new industries• do not pose unmanageable health and safety hazards

and pollution

• adopt clean technology to minimise the use of hazardous chemicals and the generation of wastes

• can comply with prescribed standards for the emission/discharge of pollutants

• wastes can be properly handled and disposed of

• compatible with surrounding land use

Building Plan Control

• Check building plans of new developments

• Check pollution control facilities of industrial developments

• Check completed developments for compliance with pollution control requirements before occupation and use of developments

Environmental Monitoring• Monitor ambient air quality and quality of

inland and coastal waters

• Detect trends so that control programmes can be formulated to prevent a problem from arising

• Assess adequacy and effectiveness of control programmes

• Keep abreast with monitoring technology

Telemetric Air Quality Monitoring & Management System

• Air monitoring stations are equipped with continuous automatic analysers for sulphur dioxide ozone carbon monoxide oxides of nitrogen particulate matter

Legislation & Policies

• Set up effective legislation to control pollution

• Carry out regular review of policies and standards with extensive consultations with the public and industries

Enforcement• Ensure air pollutant emission standards

and trade effluent standards comply with legal standards

• Control the proper management and disposal of hazardous substances and toxic industrial wastes

• Conduct regular checks on industries

• Take legal action against recalcitrant polluters

Environmental Infrastructure

• Comprehensive sewerage system

• Efficient solid waste system

Sewerage System• Separate sewerage system for both domestic

and industrial wastewater and open drainage for rain water

• 6 water reclamation plants• 2,800 km sewers• >100 pumping stations• 97% population served and remaining 3% by

on-site sewage treatment plants• Industrial wastewater pretreated to prescribed

standards prior to discharging into the sewerage system

Solid Waste Management• Daily refuse collection service• Toxic industrial wastes segregated at source

and collected by licensed toxic industrial waste collectors for treatment and disposal

• 90% of wastes generated is incinerated at 4 incineration plants

• Ash from the refuse incineration plants and 10% of wastes generated are disposed of at the off-shore Semakau sanitary landfill
