Effluent standards for developing countries: combining the technology- and water quality-based approach.

Area of Science:

• Environmental Science
• Water Resource Management
• Environmental Policy

Background:

• Developing countries face challenges in balancing socio-economic development with water resource protection.
• Effective effluent standards are crucial for controlling water pollution but are often poorly defined in developing nations.
• Existing standards may be too stringent or too relaxed, failing to ensure safe water use.

Purpose of the Study:

• To analyze and compare water quality management practices in various global regions.
• To develop a suitable approach for setting effluent standards in developing countries.
• To assess practices based on environmental protection, technical viability, economic feasibility, and institutional capacity.

Main Methods:

• Comparative analysis of water quality management practices in the USA, EU, New Independent States (NIS), and the Philippines.
• Evaluation of practices using four key criteria: environmental protection, technical viability, economic feasibility, and institutional capacity.
• Assessment of the suitability of these practices for the specific needs and resources of developing countries.

Main Results:

• Water quality management practices vary significantly across different regions.
• No single existing model perfectly fits the needs of developing countries.
• A combined approach appears most promising for balancing pollution control with affordability.

Conclusions:

• A hybrid approach combining Best Available Technology Not Entailing Excessive Cost (BATNEEC) and environmental quality standards is recommended.
• This approach aims to restrict water pollution effectively while remaining economically feasible for developing nations.
• Implementing appropriate effluent standards is vital for sustainable water resource management and development.
